Proposal for a EUROPEAN PARLIAMENT AND COUNCIL DIRECTIVE relating to the frontal impact resistance of motor vehicles and amending Directive 70/156/EEC /* COM/94/520FINAL - COD 94/0323 */

Official Journal C 396 , 31/12/1994 P. 0034


Proposal for a European Parliament and Council Directive relating to the frontal impact resistance of motor vehicles and amending Directive 70/156/EEC (94/C 396/02) (Text with EEA relevance) COM(94) 520 final - 94/0323(COD)

(Submitted by the Commission on 30 January 1995)

THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION,

Having regard to the Treaty establishing the European Community and in particular Article 100a,

Having regard to the proposal from the Commission,

Having regard to the opinion of the Economic and Social Committee,

Having regard to Council Directive 70/156/EEC of 6 February 1970 on the approximation of the laws of the Member States relating to the type-approval of motor vehicles and their trailers (1), as last amended by Commission Directive 93/81/EEC (2), and in particular Article 13 (4) thereof,

Whereas the internal market comprises an area without internal frontiers in which the free movement of goods, persons, services and capital must be ensured; whereas total harmonization of technical requirements for motor vehicles is necessary in order fully to achieve that objective;

Whereas in order to reduce the number of European road accident casualties it is necessary to introduce legislative measures for the improvement of vehicular crash worthiness as far as practicable; whereas this Directive introduces frontal impact test requirements, including biomechanical criteria, to ensure that a high level of frontal impact resistance is provided;

Whereas in the 'Outcome of Proceedings` the Council Working Party on Economic Questions, in reaching a coordinated view prior to the 101st meeting of the United Nations Economic Commission for Europe (ECE) Working Party on the Construction of Motor Vehicles (WP29), confirmed their preference for a two-stage approach, reiterated their agreement to comply with the dates of 1 October 1995 for the first stage and 1 October 1998 for the second, and called upon the Commission to monitor the parallelism between Community regulations and the regulations of the ECE in Geneva (3).

Whereas the aim of this Directive is to introduce requirements based on the results of research which will be published in 1995, allowing the establishment of test criteria more representative of actual road accidents;

Whereas lead times are necessarily required by vehicle manufacturers for the implemention of acceptable test criteria as recently developed by the UNECE (4);

Whereas the offset deformable barrier test criteria represents a significant enhancement of safety standards in respect of frontal impact; whereas the technical details are not yet finalized;

Whereas in the meantime an intermediate standard, the 30° angled rigid barrier test, will provide an improved level of safety pending the finalization of the technical requirements for the offset deformable barrier test;

Whereas this Directive will be one of the separate directives which must be complied with in order to conform to the EEC type-approval procedure established by Directive 70/156/EEC; whereas, consequently, the provisions laid down in Directive 70/156/EEC relating to vehicle systems, components and separate technical units apply to this Directive;

Whereas the procedure for determining the reference point for seating positions in motor vehicles is given in Annex III to Council Directive 77/649/EEC (5), as last amended by Commission Directive 90/630/EEC (6), and consequently it is not necessary to repeat it in this Directive; whereas reference is made to Council Directive 77/541/EEC (7), as last amended by Commission Directive 90/628/EEC (8), Council Directive 76/115/EEC (9), as last amended by Commission Directive 90/629/EEC (10) and Council Directive 74/297/EEC (11), as last amended by Commission Directive 91/662/EEC (12), whereas reference is made to Code of Federal Regulations 49 CFR Part 572 (13),

Appendix 2

DETERMINATION OF PERFORMANCE CRITERIA

1. HEAD PERFORMANCE CRITERION (HPC)

1.1. This criterion is considered to be satisfied when, during the test, there is no contact between the head and any vehicle component.

1.2. If that is not the case, a calculation of the value of HPC is made, on the basis of the acceleration (a), measured according to Annex II, Appendix 1, paragraph 5.2.1, by the following expression:

>START OF GRAPHIC>

>END OF GRAPHIC>

in which:

1.2.1. if the beginning of the head contact can be determined satisfactority, t1 and t2 are the two time instants, expressed in seconds, defining an interval between the beginning of the head contact and the end of the recording for which the value of HPC is maximum;

1.2.2. if the beginning of the head contact cannot be determined, t1 and t2 are the two time instants, expressed in seconds, defining a time interval between the beginning and the end of the recording for which the value of HPC is maximum.

2. THORAX PERFORMANCE CRITERION (ThPC)

2.1. This criterion is determined by the absolute value of the thorax deformation, expressed in mm and measured according to Annex II, Appendix 1, paragraph 5.2.2.

3. FEMUR PERFORMANCE CRITERION (FPC)

3.1. This criterion is determined by the compression load expressed in kN, transmitted axially on each femur of the dummy and measured according to Annex II, Appendix 1, paragraph 5.2.3.

Appendix 3

TECHNIQUE OF MEASUREMENT IN MEASUREMENT TESTS INSTRUMENTATION

1. DEFINITIONS

1.1. Data channel

A data channel comprises all the instrumentation from a transducer (or multiple transducers whose outputs are combined in some specified way) up to and including any analysis procedures that may alter the frequency content or the amplitude content of data.

1.2. Transducer

The first device in a data channel used to convert a physical quantity to be measured into a second quantity (such as an electrical voltage) which can be processed by the remainder of the channel.

1.3. Channel amplitude class: CAC

The designation for a data channel that meets certain amplitude characteristics as specified in this Appendix. The CAC number is numerically equal to the upper limit of the measurement range.

1.4. Characteristic frequencies FH, FL, FN

These frequencies are defined in Figure 1.

1.5. Channels frequency class: CFC

The channel frequency class is designated by a number indicating that the channel frequency response lies within the limits specified in Figure 1. This number and the value of the frequency FH in Hz are numerically equal.

1.6. Sensitivity coefficient

The slope of the straight line representing the best fit to the calibration values determined by the method of least square within the channel amplitude class.

1.7. Calibration factor of a data channel

The mean value of the sensitivity coefficients evaluated over frequencies which are evenly spaced on a logarithmic scale between FL and 0,4 FH.

1.8. Linearity error

The ratio, in per cent, of the maximum difference between the calibration value and the corresponding value read on the straight line defined in paragraph 1.6 at the upper limit of the channel amplitude class.

1.9. Cross sensitivity

The ratio of the output signal to the input signal, when an excitation is applied to the transducer perpendicular to the measurement axis. It is expressed as a percentage of the sensitivity along the measurement axis.

1.10. Phase delay time

The phase delay time of a data channel is equal to the phase delay (in radians) of a sinusoidal signal, divided by the angular frequency of that signal (in radians/s).

1.11. Environment

The aggregate, at a given moment, of all external conditions and influences to which the data channel is subjected.

2. PERFORMANCE REQUIREMENTS

2.1. Linearity error

The absolute value of the linearity error of a data channel at any frequency in the CFC, shall be equal to or less than 2,5 % of the value of the CAC, over the whole measurement range.

2.2. Amplitude against frequency

The frequency response of a data channel shall lie within the limiting curves given in Figure 1. The zero dB is determined by the calibration factor.

2.3. Phase delay time

The phase delay time between the input and the output signals of a data channel shall be determined and shall not vary by more than 0,1 FHs between 0,03 FH and FH.

2.4. Time

2.4.1. Time base

A time base shall be recorded and shall at least give 10 ms with an accuracy of 1 %.

2.4.2. Relative time delay

The relative time delay between the signal of two or more data channels, regardless of their frequency class, must not exceed 1 ms excluding delay caused by phase shift.

2.6. Calibration

2.6.1. General

A data channel shall be calibrated at least once a year against reference equipment traceable to known standards. The methods used to carry out a comparison with reference equipment shall not introduce an error greater than 1 % of the CAC. The use of the reference equipment is limited to the frequency range for which they have been calibrated. Subsystems of a data channel may be evaluated individually and the results factored into the accuracy of the total data channel. This can be done for example by an electrical signal of known amplitude simulating the output signal of the transducer which allows a check to be made on the gain factor of the data channel, excluding the transducer.

The accuracy of the reference equipment shall be certified or endorsed by an official metrology service.

2.6.2.1. Static calibration

2.6.3. Sensitivity coefficient and linearity error

The sensitivity coefficient and the linearity error shall be determined by measuring the output signal of the data channel against a known input signal for various values of this signal. The calibration of the data channel shall cover the whole range of the amplitude class.

For bi-directional channels both the positive and negative values shall be used.

If the calibration equipment cannot produce the required input owing to the excessively high values of the quantity to be measured, calibrations shall be carried out within the limits of the calibration standards and these limits shall be recorded in the test report.

A total data channel shall be calibrated at a frequency or at a spectrum of frequencies having a significant value between FL and 0,4 FH.

2.6.4. Calibration of the frequency response

The response curves of phase and amplitude against frequency shall be determined by measuring the output signals of the data channel in terms of phase and amplitude against a known input signal, for various values of this signal varying between FL and 10 times the CFC or 3 000 Hz, whichever is lower.

2.7. Environmental effects

A regular check shall be made to identify any environmental influence (such as electric or magnetic flux, cable velocity, etc.). This can be done for instance by recording the output of spare channels equipped with dummy transducers. If significant output signals are obtained corrective action shall be taken, for instance by replacement of cables.

2.8. Choice and designation of the data channel

The CAC and CFC define a data channel.

The CAC shall be 1, 2 or 5 to a power of 10.

3. MOUNTING OF TRANSDUCERS

Transducers should be rigidly secured so that their recordings are affected by vibration as little as possible. Any mounting having a lowest resonance frequency equal to at least five times the frequency FH of the data channel considered shall be considered valid. Acceleration transducers in particular should be mounted in such a way that the initial angle of the real measurement axis to the corresponding axis of the reference axis system is not greater than 5° unless an analytical or experimental assessment of the effect of the mounting on the collected data is made. When multi-axial accelerations at a point are to be measured, each acceleration transducer axis should pass within 10 mm of that point, and the centre of seismic mass of each accelerometer should be within 30 mm of that point.

4. RECORDING

4.1. Analogue magnetic recorder

Tape speed should be stable to within not more than 0,5 % of the tape speed used. The signal-to-noise ratio of the recorder should not be less than 42 dB at the maximum tape-speed. The total harmonic distortion should be less than 3 % and the linearity error should be less than 1 % of the measurement range.

4.2. Digital magnetic recorder

Tape speed should be stable to within not more than 10 % of the tape speed used.

4.3. Paper tape recorder

In case of direct data recording the paper speed in mm/s should be at least 1,5 times the number expressing FH in Hz. In other cases the paper speed should be such that equivalent resolution is obtained.

5. DATA PROCESSING

5.1. Filtering

Filtering corresponding to the frequencies of the data channel class may be carried out during either recording or processing of data. However, before recording, analogical filtering at a higher level than CFC should be effected in order to use at least 50 % of the dynamic range of the recorder and to reduce the risk of high frequencies saturating the recorder or causing aliasing errors in the digitilizing process.

5.2. Digitilizing

5.2.1. Sampling frequency

The sampling frequency should be equal to at least 8 FH. In the case of analogue recording, when the recording and reading speeds are different, the sampling frequency can be divided by the speed ratio.

5.2.2. Amplitude resolution

The size of digital words should be at least seven bits and a parity bit.

6. PRESENTATION OF RESULTS

The results should be presented on A4 size paper (210×297 mm). Results presented as diagrams should have axes sealed with a measurement unit corresponding to a suitable multiple of the chosen unit (for example, 1, 2, 5, 10, 20 mm). SI units shall be used, except for vehicle velocity, where km/h may be used, and for accelerations due to impact where g, with g = 9,81 m/s², may be used.
