This procedure shall be repeated until the illumination value has dropped to 15-20 per cent of the values measured for the following point under the conditions described in this annex:

Point of Emax in zone D.

2.   TEST FOR CHANGE IN VERTICAL POSITION OF THE CUT-OFF LINE UNDER THE INFLUENCE OF HEAT

This test consists of verifying that the vertical drift of the cut-off line under the influence of heat does not exceed the specified value for an operating front fog lamp.

The position of the cut-off line between a point situated 3,0 degrees left and a point situated 3,0 degrees right of the line v-v (see Annex 4 of the Regulation) shall be verified after three minutes (r3) and 60 minutes (r60) respectively of operation.

The measurement of the variation in the cut-off line position as described above shall be carried out by any method giving acceptable accuracy and reproducible results.

2.2.   Test results

(1)  When the tested front fog lamp includes signaling lamps, the latter shall be lit for the duration of the test, except for a daytime running lamp. In the case of a direction indicator lamp, it shall be lit in flashing operation mode with an on/off time ratio of approximately one to one.

(2)  Should two or more lamp filaments be simultaneously lit when headlamp flashing is used, this shall not be considered as being normal use of the filaments simultaneously.

If the horizontal part is not straight but slightly curved or inclined, the cut-off line shall not exceed the vertical range formed by two horizontal lines which are situated between 3° left and right of the v-v line at 0,2° above and below the nominal position of the cut-off (see Figure 1).

4.   MEASUREMENT OF THE QUALITY OF CUT-OFF

4.1.   Measurements shall be performed by vertically scanning through the horizontal part of the cut-off line in angular steps not exceeding 0,05°.

At either a measurement distance of 10 m and a detector with a diameter of approximately 10 mm.

Or at a measurement distance of 25 m and a detector with a diameter of approximately 30 mm.

The measurement of the cut-off quality shall be considered acceptable if the requirements of the paragraphs 4.1.1 to 4.1.3 of this annex shall comply with at least one measurement at 10 m or 25 m.

The measuring distance at which the test was determined shall be recorded in paragraph 9 of the communication form in Annex 2 of this Regulation.

The scanning is performed from downwards upwards through the cut-off line along the vertical lines at – 2,5° and + 2,5° from the v-v line. When so measured, the quality of the cut-off line shall meet the following requirements:

4.1.1.   Not more than one cut-off line shall be visible.

3.1.5.1.   Power supply

The power supply used for the starting and run-up tests shall be sufficient to secure the quick rise of the high current pulse.

3.1.5.2.   Burning position

The burning position shall be as indicated by the applicant. Ageing and testing positions shall be identical. If the lamp is accidentally operated in the wrong direction, it shall be re-aged before measurements begin. During ageing and measurements no electrically conducting objects shall be allowed within a space as indicated by the applicant. Moreover stray magnetic fields shall be avoided.

3.2.   Ageing

3.2.1.   LED modules or light-generators shall be aged.

3.2.2.   The tests below shall be carried out after ageing with the LED module(s) or light-generator(s) supplied by the submitted electronic light source control-gear at test voltage.

3.2.3.   LED module(s)

Upon the request of the applicant the LED module shall be operated for 15 h and cooled down to ambient temperature before starting the tests as specified in this Regulation.

3.2.4.   Filament lamps

Filament lamps shall first be aged at their test voltage for approximately one hour. For dual-filament lamps, each filament shall be aged separately.

3.2.5.   Gas discharge light sources

With the exception of the starting test, all tests shall be carried out with light sources which have been aged for a minimum of 15 cycles having the following switching cycle: 45 minutes on, 15 seconds off, 5 minutes on, 10 minutes off.

4.   SPECIFIC TESTS

Filament lamps approved according to Regulation No 37, gas-discharge light sources approved according to Regulation No 99 and LED modules are exempted from the tests indicated in paragraphs 4.3.1 and 4.3.2 below.

4.2.   Gas discharge light sources

The starting test shall be applied to light sources which have not been aged and have not been used for a period of at least 24 hours prior to the test. The light source shall start directly and remain alight.

4.3.   Run-up

4.3.1.   Filament lamps are exempted from this test.

4.3.2.   Gas discharge light sources

The run-up test shall be applied to light sources which have not been used for a period of at least 1 hour prior to the test. The front fog lamp shall reach at least in the point 0°, 2,5°D on the line 6 a luminous intensity:

4.4.   Hot re-strike

4.4.1.   Filament lamps are exempted from this test.

4.4.2.   Gas discharge light sources

The light source shall be started and be operated with the electronic light source control-gear at test voltage for a period of 15 minutes. The supply voltage to the electronic light source control-gear shall then be switched off for a period of 10 seconds, and be switched on again. The light source shall restart directly after being switched-off for a period of 10 seconds. After one second the light source shall emit at least 80 per cent of its objective luminous flux.

4.5.   Colour rendering

4.5.1.   Red content

The minimum red content of the light of a LED module or light-generator shall be such that:

where:

This value shall be calculated using intervals of one nanometre.

4.6.   UV-radiation

The UV-radiation of the LED module or light-generator shall be such that:

where:

(For definitions of the other symbols see paragraph 4.5.1)

This value shall be calculated using intervals of one nanometre. The UV-radiation shall be weighted according to the values as indicated in the UV table below.

UV Table

Values according to ‘IRPA/INIRC Guidelines on limits of exposure to ultraviolet radiation’. Wavelengths (in nanometres) chosen are representative; other values should be interpolated.

4.7.   Temperature stability

4.7.1.   Luminous intensity

4.7.2.   Colour

The colour of the light emitted, measured after 1 minute and measured after 30 minutes of operation, shall be within the required colour boundaries in both instances.
