1.   DEFINITIONS

1.1.

‘Devices for indirect vision’ means devices to observe the traffic area adjacent to the vehicle which cannot be observed by direct vision. These can be conventional mirrors, camera-monitors or other devices able to present information about the indirect field of vision to the driver. 1.1.1. ‘Mirror’ means any device, excluding devices such as periscopes, intended to give a clear view to the rear, side or front of the vehicle within the fields of vision defined in point 5 of Annex III. 1.1.1.1. ‘Interior mirror’ means a device as defined in point 1.1, which can be fitted in the passenger compartment of a vehicle. 1.1.1.2. ‘Exterior mirror’ means a device as defined in point 1.1, which can be mounted on the external surface of a vehicle. 1.1.1.3. ‘Surveillance mirror’ means a mirror other than the ones defined in point 1.1.1, which can be fitted to the inside or outside of the vehicle in order to provide fields of vision other than those specified in point 5 of Annex III. 1.1.1.4. ‘r’ means the average of the radii of curvature measured over the reflecting surface, in accordance with the method described in point 2 of Appendix 1 to Annex II. 1.1.1.5. ‘The principal radii of curvature at one point on the reflecting surface (ri)’ means the values obtained with the apparatus defined in Appendix 1 to Annex II, measured on the arc of the reflecting surface passing through the centre of this surface parallel to the segment b, as defined in point 2.2.1 of Annex II and on the arc perpendicular to this segment. 1.1.1.6. ‘The radius of curvature at one point on the reflecting surface (rp)’ means the arithmetical average of the principal radii of curvature ri and r′i, i.e.: 1.1.1.7. ‘Spherical surface’ means a surface which has a constant and equal radius in all directions. 1.1.1.8. ‘Aspherical surface’ means a surface which has only in one plane a constant radius. 1.1.1.9. ‘Aspherical mirror’ means a mirror composed of a spherical and an aspherical part, in which the transition of the reflecting surface from the spherical to the aspherical part has to be marked. The curvature of the main axis of the mirror is defined in the x/y coordinate system defined by the radius of the spherical primary calotte with: R : nominal radius in the spherical part k : constant for the change of curvature a : constant for the spherical size of the spherical primary calotte 1.1.1.10. ‘Centre of the reflecting surface’ means the centre of the visible area of the reflecting surface. 1.1.1.11. ‘The radius of curvature of the constituent parts of the mirror’ means the radius ‘c’ of the arc of the circle which most closely approximates to the curved form of the part in question. 1.1.1.12. ‘The driver's ocular points’ means two points 65 mm apart and 635 mm vertically above point R of the driver's seat as defined in Appendix 6 to this Annex. ►M1  In the case of a seat with fixed seat-back angle, the location of the ocular points shall be adjusted in accordance with the provisions of Appendix 7 to this Annex. ◄ The straight line joining these points runs perpendicular to the vertical longitudinal median plane of the vehicle. The centre of the segment joining the two ocular points is in a vertical longitudinal plane which must pass through the centre of the driver's designated seating position, as specified by the vehicle manufacturer. 1.1.1.13. ‘Ambinocular vision’ means the total field of vision obtained by the superimposition of the monocular fields of the right eye and the left eye (see figure 1 below). 1.1.1.14. ‘Class of mirror’ means all devices having one or more common characteristics or functions.

ANNEX II

DESIGN SPECIFICATIONS AND TESTS REQUIRED FOR EC COMPONENT TYPE-APPROVAL OF A DEVICE FOR INDIRECT VISION

A.   MIRRORS

1.   General specifications

1.1.	All mirrors must be adjustable.

1.2.

The edge of the reflecting surface must be enclosed in a protective housing (holder, etc.) which, on its perimeter, must have a value ‘c’ greater than or equal to 2,5 mm at all points and in all directions. If the reflecting surface projects beyond the protective housing, the radius of curvature ‘c’ on the edge of the projecting part must be not less than 2,5 mm and the reflecting surface must return into the protective housing under a force of 50 N applied to the point of greatest projection, relative to the protective housing, in a horizontal direction, approximately parallel to the longitudinal median plane of the vehicle.

1.3.

When the mirror is mounted on a plane surface, all parts, irrespective of the adjustment position of the device, including those parts remaining attached to the support after the test provided for in point 4.2, which are in potential, static contact with a sphere either 165 mm in diameter in the case of an interior mirror or 100 mm in diameter in the case of an exterior mirror, must have a radius of curvature ‘c’ of not less than 2,5 mm. 1.3.1. Edges of fixing holes or recesses of which the diameter or longest diagonal is less than 12 mm are exempt from the radius requirements of point 1.3 provided that they are blunted.

1.4.

The device for the attachment of mirrors to the vehicle must be so designed that a cylinder with a 70 mm radius, having as its axis the axis, or one of the axes, of pivot or rotation which ensures deflection of the mirror in the direction of impact concerned, passes through at least part of the surface to which the device is attached.

1.5.	The parts of exterior mirrors referred to in points 1.2 and 1.3 which are made of a material with a Shore A hardness not exceeding 60 are exempt from the relevant provisions.

1.6.	In the case of those parts of interior mirrors which are made of a material with a Shore A hardness of less than 50 and which are mounted on a rigid support, the requirements of points 1.2 and 1.3 shall only apply to the support.

2.   Dimensions

2.1.   Interior rear-view mirrors (Class I)

The dimensions of the reflecting surface must be such that it is possible to inscribe thereon a rectangle one side of which is 40 mm and the other ‘a’ mm in length, where

and r is the radius of curvature.

2.2.   Main exterior rear-view mirrors (Classes II and III)

2.3.   ‘Wide-angle’ exterior mirrors (Class IV)

The contours of the reflecting surface must be of simple geometric form and its dimensions such that it provides, if necessary in conjunction with a Class II exterior mirror, the field of vision specified in point 5.4 of Annex III.

2.4.   ‘Close-proximity’ exterior mirrors (Class V)

The contours of the reflecting surface must be of simple geometric form and its dimensions such that the mirror provides the field of vision specified in point 5.5 of Annex III.

2.5.   Front mirrors (Class VI)

The contours of the reflecting surface must be of simple geometric form and its dimensions such that the mirror provides the field of vision specified in point 5.6 of Annex III.

3.   Reflecting surface and coefficients of reflection

3.1.	The reflecting surface of a mirror must be either flat or spherically convex. Exterior mirrors may be equipped with an additional aspherical part provided that the main mirror fulfils the requirements of the indirect field of vision.

3.2.

Differences between the radii of curvature of mirrors 3.2.1. The difference between ri or r′i, and rp at each reference point must not exceed 0,15 r. 3.2.2. The difference between any of the radii of curvature (rp1, rp2, and rp3) and r must not exceed 0,15 r. 3.2.3. When r is not less than 3 000 mm, the value of 0,15 r quoted in points 3.2.1 and 3.2.2 is replaced by 0,25 r.

3.3.

Requirements for aspherical parts of mirrors 3.3.1. Aspherical mirrors shall be of sufficient size and shape to provide useful information to the driver. This normally means a minimum width of 30 mm at some point. 3.3.2. The radius of curvature ri of the aspherical part shall not be less than 150 mm.

3.4.

Value of ‘r’ for spherical mirrors must not be less than: 3.4.1. 1 200 mm for interior rear-view mirrors (Class I); 3.4.2. 1 200 mm for Class II and III main exterior rear-view mirrors; 3.4.3. 300 mm for ‘wide-angle’ exterior mirrors (Class IV) and ‘close-proximity’ exterior mirrors (Class V); 3.4.4. 200 mm for front mirrors (Class VI).

3.5.

The value of the normal coefficient of reflection, as determined according to the method described in Appendix 1 to this Annex, must be not less than 40 %. In the case of reflecting surfaces with a changeable degree of reflection, the ‘day’ position must allow the colours of the signals used for road traffic to be recognised. The value of the normal coefficient of reflection in the ‘night’ position must be not less than 4 %.

3.6.	The reflecting surface must retain the characteristics laid down in point 3.5 in spite of prolonged exposure to adverse weather conditions in normal use.

4.   Tests

4.1.

Mirrors shall be subjected to the tests described in point 4.2. 4.1.1. The test provided for in point 4.2 shall not be required in the case of any exterior mirror of which no part is less than 2 m from the ground, regardless of the adjustment position, when the vehicle is under a load corresponding to its maximum technically permissible mass. This derogation also applies to the attachments of mirrors (attachment plates, arms, swivel joints, etc.) which are situated less than 2 m from the ground and which do not project beyond the overall width of the vehicle, measured in the transverse plane passing through the lowest mirror attachments or any other point forward of this plane if this configuration produces a greater overall width. In such cases, a description specifying that the mirror must be mounted so as to conform to the abovementioned conditions for the positioning of its attachments on the vehicle must be provided. Where advantage is taken of this derogation, the arm shall be indelibly marked with the symbol and the type-approval certificate shall be endorsed to this effect.

4.2.

Impact test The test according to this paragraph is not to be carried out for devices integrated in the bodywork of the vehicle and providing a frontal deflecting area of an angle not more than 45 ° measured in relation to the longitudinal median plane of the vehicle, or devices not protruding more than 100 mm measured beyond the circumscribing bodywork of the vehicle according to 74/483/EEC. 4.2.1.   Description of the test rig 4.2.1.1. The test rig consists of a pendulum capable of swinging about two horizontal axes at right angles to each other, one of which is perpendicular to the plane containing the ‘release’ trajectory of the pendulum. The end of the pendulum comprises a hammer formed by a rigid sphere with a diameter of 165 ± 1 mm having a 5 mm thick rubber covering of Shore A hardness 50. A device is provided which permits determination of the maximum angle assumed by the arm in the plane of release. A support firmly fixed to the structure of the pendulum serves to hold the specimens in compliance with the impact requirements specified in point 4.2.2.6. 4.2.1.2. The centre of percussion of the pendulum coincides with the centre of the sphere, which forms the hammer. It is at a distance ‘l’ from the axis of oscillation in the release plane, which is equal to 1 m ± 5 mm. The reduced mass of the pendulum is mo= 6,8 ± 0,05 kilograms. The relationship of ‘mo’ to the total mass ‘m’ of the pendulum and to the distance ‘d’ between the centre of gravity of the pendulum and its axis of rotation is expressed in the equation: 4.2.2.   Description of the test 4.2.2.1. The procedure used to clamp the mirror to the support shall be that recommended by the manufacturer of the device or, where appropriate, by the vehicle manufacturer. 4.2.2.2. Positioning of the mirror for the test 4.2.2.2.1. Mirrors shall be positioned on the pendulum impact rig in such a way that the axes which are horizontal and vertical when the mirror is installed on a vehicle in accordance with the applicant's mounting instructions are in a similar position. 4.2.2.2.2. When a mirror is adjustable with respect to the base, the test position shall be that in which any pivoting device is least likely to operate, within the limits of adjustment provided by the applicant. 4.2.2.2.3. When the mirror has a device for adjusting its distance from the base, the device must be set in the position in which the distance between the housing and the base is shortest. 4.2.2.2.4. When the reflecting surface is mobile in the housing, it shall be so adjusted that the upper corner, which is furthest from the vehicle, is in the position of greatest projection relative to the housing. 4.2.2.3. Except in the case of test 2 for interior mirrors (see point 4.2.2.6.1), when the pendulum is in a vertical position, the horizontal and longitudinal vertical planes passing through the centre of the hammer shall pass through the centre of the reflecting surface as defined in point 1.1.1.10 of Annex I. The longitudinal direction of oscillation of the pendulum shall be parallel to the longitudinal median plane of the vehicle. 4.2.2.4. When, under the conditions governing adjustment laid down in points 4.2.2.1 and 4.2.2.2 parts of the mirror limit the return of the hammer, the point of impact must be displaced in a direction perpendicular to the axis of rotation or pivoting in question. The displacement must be no greater than is strictly necessary for the execution of the test; it must be limited in such a way that: — either the sphere delimiting the hammer remains at least tangential to the cylinder as defined in point 1.4; — or the point of contact with the hammer is located at least 10 mm from the periphery of the reflecting surface. 4.2.2.5. The test consists in allowing the hammer to fall from a height corresponding to a pendulum angle of 60 ° from the vertical so that the hammer strikes the mirror at the moment when the pendulum reaches the vertical position. 4.2.2.6. The mirrors are subjected to impact under the following different conditions: 4.2.2.6.1. Interior mirrors — Test 1:The points of impact shall be as defined in point 4.2.2.3. The impact must be such that the hammer strikes the mirror on the reflecting surface side. — Test 2: Point of impact on the edge of the protective housing, such that the impact produced makes an angle of 45 ° with the plane of the reflecting surface and is situated in the horizontal plane passing through the centre of that surface. The impact must occur on the reflecting surface side. 4.2.2.6.2. Exterior mirrors — Test 1: The point of impact shall be as defined in point 4.2.2.3 or 4.2.2.4. The impact must be such that the hammer strikes the mirror on the reflecting surface side. — Test 2: The point of impact shall be as defined in point 4.2.2.3 or 4.2.2.4. The impact must be such that the hammer strikes the mirror on the side opposite to the reflecting surface. Where Class II or III rear-view mirrors are fixed to the same mounting as Class IV rear-view mirrors, the abovementioned tests shall be executed on the lower mirror. Nevertheless, the technical service responsible for testing may repeat one or both of these tests on the upper mirror if this is less than 2 m from the ground.

5.   Results of the test

5.1.

In the tests described in point 4.2, the pendulum must continue to swing after impact in such a way that the projection of the position assumed by the arm on the plane of release makes an angle of at least 20 ° with the vertical. The accuracy of measurement of the angle shall be within ± 1 °. 5.1.1. This requirement is not applicable to mirrors stuck to the windscreen, in respect of which the requirement stipulated in point 5.2 shall apply after the test. 5.1.2. The required angle to the vertical is reduced from 20 ° to 10 ° for all Class II and Class IV rear-view mirrors and for Class III rear-view mirrors which are attached to the same mounting as Class IV mirrors.

5.2.	Should the mounting of the mirror break during the tests described in point 4.2 for mirrors stuck to the windscreen, the part remaining must not project beyond the base by more than 10 mm and the configuration remaining after the test must satisfy the conditions laid down in point 1.3.

5.3.

The reflecting surface must not break during the tests described in point 4.2. However breakage of the reflecting surface will be allowed if one of the following conditions is fulfilled: 5.3.1. The fragments of glass still adhere to the back of the housing or to a surface firmly attached to the housing; partial separation of the glass from its backing is admissible provided this does not exceed 2,5 mm on either side of the cracks. It is permissible for small splinters to become detached from the surface of the glass at the point of impact; 5.3.2. The reflecting surface is made of safety glass.

Appendix 2

Test method for determining reflectivity

1.   DEFINITIONS

2.   APPARATUS

2.1.   General

The apparatus shall consist of a light source, a holder for the test sample, a receiver unit with a photodetector and an indicating meter (see Figure 4), and means of eliminating the effects of extraneous light.

The receiver may incorporate a light-integrating sphere to facilitate measuring the reflectance of non-flat (convex) mirrors (see Figure 5).

2.2.   Spectral characteristics of light source and receiver

The light source shall consist of a CIE standard source A and associated optics to provide a near-collimated light beam. A voltage stabiliser is recommended in order to maintain a fixed lamp voltage during instrument operation.

The receiver shall have a photodetector with a spectral response proportional to the photopic luminosity function of the CIE (1931) standard colorimetric observer (see table). Any other combination of illuminate-filter-receptor giving the overall equivalent of CIE standard illuminate A and photopic vision may be used. When an integrating sphere is used in the receiver, the interior surface of the sphere shall be coated with a matt (diffusive) spectrally non-selective white coating.

2.3.   Geometrical conditions

The angle of the incident beam (θ) should preferably be 0,44 ± 0,09 rad (25 ± 5 °) from the perpendicular to the test surface and shall not exceed the upper limit of the tolerance (i.e. 0,53 rad or 30 °). The axis of the receptor shall make an angle (θ) with this perpendicular equal to that of the incident beam (see Figure 4). The incident beam upon arrival at the test surface shall have a diameter of not less than 13 mm (0,5 in.). The reflected beam shall not be wider than the sensitive area of the photodetector, shall not cover less than 50 % of such area, and as nearly as possible shall cover the same area segment as used during instrument calibration.

When an integrating sphere is used in the receiver section, the sphere shall have a minimum diameter of 127 mm (5 in.). The sample and incident beam apertures in the sphere wall shall be of such a size as to admit the entire incident and reflected light beams. The photodetector shall be so located as not to receive direct light from either the incident or the reflected beam.

2.4.   Electrical characteristics of the photodetector-indicator unit

The photodetector output as read on the indicating meter shall be a linear function of the light intensity of the photosensitive area. Means (electrical and/or optical) shall be provided to facilitate zeroing and calibration adjustments. Such means shall not affect the linearity or the spectral characteristics of the instrument. The accuracy of the receptor-indicator unit shall be within ± 2 % of full scale, or ± 10 % of the magnitude of the reading, whichever is the smaller.

2.5.   Sample holder

The mechanism shall be capable of locating the test sample so that the axes of the source arm and receptor intersect at the reflecting surface. The reflecting surface may lie within or at either face of the mirror sample, depending on whether it is a first-surface, second-surface or prismatic ‘flip’-type mirror.

3.   PROCEDURE

3.1.   Direct calibration method

In the direct calibration method, air is used as the reference standard. This method is applicable for those instruments, which are so constructed as to permit calibration at the 100 % point by swinging the receiver to a position directly on the axis of the light source (see Figure 4).

It may be desired in some cases (such as when measuring low-reflectivity surfaces) to use an intermediate calibration point (between 0 and 100 % on the scale) with this method. In these cases, a neutral density filter of known transmittance shall be inserted in the optical path, and the calibration control shall then be adjusted until the meter reads the percentage transmission of the neutral density filter. This filter shall be removed before reflectivity measurements are performed.

3.2.   Indirect calibration method

The indirect calibration method is applicable in the case of instruments with fixed source and receiver geometry. A properly calibrated and maintained reflectance standard is required. This reference standard should preferably be a flat mirror with a reflectance value as near as possible to that of the test samples.

3.3.   Flat mirror measurement

The reflectance of flat mirror samples can be measured on instruments employing either the direct or the indirect calibration method. The reflectance value is read directly from the indicating meter.

3.4.   Non-flat (convex) mirror measurement

Measurement of the reflectance of non-flat (convex) mirrors requires the use of instruments which incorporate an integrating sphere in the receiver unit (see Figure 5). If the instrument-indicating meter indicates ne divisions with a standard mirror of E % reflectance, then, with a mirror of unknown reflectance, nx divisions will correspond to a reflectance of X %, in accordance with the formula:

If the vertical transverse plane passing through the leading edge of the vehicle bumper is less than 1 m in front of the vertical plane passing through the driver's ocular points, the field of vision shall be limited to that plane.

5.5.5.

In case the field of vision described in Figures 10a and 10b can be perceived through the combination of the field of vision from a Class IV wide-angle mirror and that of a Class VI front mirror, the installation of a Class V close proximity mirror is not compulsory. Figures 10a and 10b: Field of vision of Class V close-proximity mirror

5.6.   Front mirror (Class VI)

5.6.1.

The field of vision must be such that the driver can see at least a flat horizontal portion of the road, which is bounded by: — one traverse vertical plane through the outermost point of the front of the vehicle-cab — one traverse vertical plane 2 000 mm in front of the vehicle — one longitudinal vertical plane parallel to the longitudinal vertical median plane going though the outermost side of the vehicle at the driver's side and — one longitudinal vertical plane parallel to the longitudinal vertical median plane 2 000 mm outside the outermost side of the vehicle opposite to the driver's side. The front of this field of vision opposite to the driver's side may be rounded off with a radius of 2 000 mm (see Figure 11). The provisions for front mirrors are compulsory for forward-controlled (as defined in Directive 70/156/EEC, Annex I(a), footnote (Z)) vehicles of categories N2> 7,5 t and N3. If vehicles of these categories with other construction characteristics regarding the bodywork cannot fulfil the requirements by using a front mirror, a camera/monitor device shall be used. If either of these options do not provide the adequate field of vision then any other device for indirect vision shall be used. This device must be able to detect an object of 50 cm height and with a diameter of 30 cm within the field defined in Figure 11. Figure 11: Field of vision of Class VI front mirror

5.6.2.

However, if the driver can see, taking into account the obstructions by the A-pillars, a straight line 300 mm in front of the vehicle at a height of 1 200 mm above the road surface and which is situated between a longitudinal vertical plane parallel to the longitudinal vertical median plane going through the outermost side of the vehicle at the driver's side and a longitudinal vertical plane parallel to the longitudinal vertical median plane 900 mm outside the outermost side of the vehicle opposite to the driver's side, a front mirror of class VI is not mandatory.

5.7.

In the case of mirrors consisting of several reflecting surfaces which are either of a different curvature or make an angle with each other, at least one of the reflecting surfaces must provide the field of vision and have the dimensions (see point 2.2.2 of Annex II) specified for the class to which they belong.

5.8.

Obstructions 5.8.1.   Interior rear-view mirror (Class I) The field of vision may be reduced by the presence of headrest and devices such as, in particular, sun visors, rear windscreen wipers, heating elements and stop lamp of category S3 or by components of bodywork such as window columns of rear split doors, provided that all these devices together do not obscure more than 15 per cent of the prescribed field of vision when projected onto a vertical plane perpendicular to the longitudinal median plane of the vehicle. The degree of obstruction shall be measured with the headrests adjusted to their lowest possible position and with the sun visors folded back. 5.8.2.   Exterior mirrors (Classes II, III, IV, V and VI) In the fields of vision specified above, obstruction due to the bodywork and some of its components, such as other mirrors, door handles, outline marker lights, direction indicators and rear bumpers, as well as reflective-surface cleaning components, shall not be taken into account if they are responsible for a total obstruction of less than 10 % of the specified field of vision.

5.9.	Test procedure The field of vision shall be determined by placing powerful light sources at the ocular points and examining the light reflected on the vertical monitoring screen. Other equivalent methods may be used.

Devices for indirect vision other than mirrors

6.	A device for indirect vision shall give such performances that a critical object can be observed within the described field of vision, taking into account the critical perception.

7.	Obstruction of the driver's direct view caused by the installation of a device for indirect vision shall be restricted to a minimum.

8.	For the determination of the detection distance in case of camera-monitor devices for indirect vision, the procedure of the Appendix to this Annex shall be applied.

9.	Installation requirements for the monitor The viewing direction of the monitor shall roughly be the same direction as the one for the main mirror.

10.

Vehicles of category M2 and M3 and complete or completed vehicles of categories N2>7,5 t and N3 having a special bodywork for refuse collection may be equipped on the rear part of their bodywork with a device for indirect vision other than a mirror in order to ensure the following field of vision. 10.1. The field of vision (see figure 12) must be such that the driver can see at least a flat horizontal portion of the road, which is bounded by: — a vertical plane aligned on the furthest rear point of the complete vehicle and perpendicular to the longitudinal vertical median plane of the vehicle; — a vertical plane which is parallel to and positioned 2 000 mm to the rear of the previous plane (with respect to the rear of the vehicle); — two longitudinal vertical planes defined at the outermost sides of the vehicle and which are parallel to the longitudinal vertical median plane of the vehicle. 10.2. If vehicles of these categories cannot fulfil the requirements of point 10.1 by using a camera/monitor device, other devices for indirect vision can be used. In this case the device must be able to detect an object of 50 cm height and with a diameter of 30 cm within the field defined in point 10.1.

Appendix

Calculation of the detection distance

1.   CAMERA MONITOR DEVICE FOR INDIRECT VISION

1.1.   Resolution threshold of a camera

The resolution threshold of a camera is defined by the formula:

where:

ωc

:

resolution threshold of the camera (arc-min)

βc

:

angle of vision of the camera (°)

Nc

:

number of video lines of the camera

The manufacturer shall supply the values for βc and Nc.

1.2.   Determination of the critical viewing distance of the monitor

For a monitor having certain dimensions and properties, a distance to the monitor can be calculated within which the detection distance is dependent only on the performances of the camera. This critical viewing distance rm,c is defined by:

where:

rm,c

:

critical viewing distance (m)

Hm

:

height of the monitor image (m)

Nm

:

number of video lines of the monitor (-)

ωeye

:

resolution threshold of the observer (minutes of arch)

The number 60 is for conversion from minutes of arches to degrees.

The manufacturer shall supply the values for Hm and Nm.

ωeye = 1

1.3.   Determination of the detection distance

1.3.1.

Maximum detection distance within the critical viewing distance where, due to the installation, the distance eye-monitor is less than the critical viewing distance, the maximum attainable detection distance shall be defined by: where: rd : detection distance [m] Do : diameter of the object [m] f : threshold increasing factor ωc, βc and Nc according to item 1.1 D0= 0,8 m f = 8

1.3.2.

Detection distance greater than the critical viewing distance. Where, due to the installation, the distance eye-monitor is more than the critical viewing distance, the maximum obtainable detection distance shall be defined: where: rm : viewing distance to the monitor (m) Dm : diagonal of the monitor screen (inch) Nm : number of video lines of the monitor (-) βc and Nc according to point 1.1 Nm and ωeye according to point 1.2

2.   SECONDARY FUNCTIONAL REQUIREMENTS

Based on the installation conditions, a determination shall be made to discover whether the entire device can still satisfy the functional requirements listed in Annex II, especially the glare correction, the maximum and the minimum luminance of the monitor. It shall also be determined the degree to which the glare correction will be addressed and the angle at which sunlight can strike a monitor and these shall be compared to the corresponding measuring results from the system measurements.

This can be based on either a CAD-generated model, a determination of the angles of light for the device when mounted on the relevant vehicle, or by carrying out relevant measurements on the relevant vehicle as described in Annex II, part B, point 3.2.

( 7 ) A system for indirect vision is intended to detect relevant road users. The relevancy of a road user is defined by his or her position and (potential) speed. More or less in proportion with the speed of the pedestriancyclistmoped driver, the dimensions of these road users increase as well. For detection purposes a moped driver (D = 0,8) at 40 m distance would be equal to a pedestrian (D = 0,5) at a distance of 25 m. Considering the speeds, the moped driver would be selected as the criterion for the detection size; for that reason an object with a size of 0,8 m shall be used for determining the detection performance.
