1、INTERNATIONAL STANDARD IS0 10604 First edition 1993-02-01 Road vehicles - Measurement equipment for orientation of headlamp luminous beams V b) the vehicle preparation; c) equipment using a distant screen; d) optical equipment with installation and operating instructions; IS0 1176:1990, Road vehicle
2、s - Masses - Vocabu- lary and codes. 3 Definitions For the purposes of this International Standard, the following definitions apply. 3.1 test area floor: Delimited area on which the vehicles are placed to measure or to verify the orien- tation of the luminous beams emitted by their head- lamps. 3.2
3、reference plane: Plane characterizing the test area floor. 3.3 vehicle direction: Direction parallel to the refer- ence plane and to the median longitudinal plane of the vehicle standing on the test area floor. 3.4 headlamp: Lighting device able to emit at least a main beam, a dipped beam or a front
4、 fog beam but with a single aiming even if different beams can be emitted. e) photometric devices (see clause 12). 3.5 beam axis: Reference axis according to beam pattern requirements. NOTE 1 In the case of reciprocally incorporated lamps, the beam axes of the beams emitted by the same headlamp may
5、be different. 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publi- cation, the edition indicated was valid. All standards are subject to revision, and parties to agreements
6、based on this International Standard are encouraged to investigate the possibility of applying the most re- cent edition of the standard indicated below. Mem- bers of IEC and IS0 maintain registers of currently valid International Standards. 3.6 aiming screen: Screen on which the headlamp beam patte
7、rn can be observed. 3.7 optical block: Device focussing the headlamp beam on an aiming screen and allowing a vertical displacement of the aiming screen or of the beam image, calibrated on an inclination scale. 3.8 optical apparatus: Optical block mounted on a frame allowing positioning and alignment
8、 of the op- tical block in front of the headlamp. 1 Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=Defense Supply Ctr/9960866100 Not for Resale, 04/24/2007 10:06:16 MDTNo reproduction or networking permitted without license from IHS -,-,- IS0
9、 3.9 10604:1993(E) screen reference point: Intersecting point on the aiming screen of a light ray parallel to the vehicle direction originating from the lens centre of the headlamp under test, in the reference position in the case of an optical apparatus. 3.10 reference position of optical apparatus
10、: Position of the optical block and of the inclination scale so that the reference point on the aiming screen represents the vehicle direction. 3.11 inclination: Tangent, expressed in per cent of the up- or downward angle with regard to the vehicle direction.) a) maximum distance between the tracks
11、0.9 m bl minimum overall width: - for passenger cars 2m - for any motor vehicle 2,3 m c) minimum length - for passenger cars 4m - for any motor vehicle El,5 m However, in the case of equipment intended exclus- ively for checking one type or certain types of defined vehicles, the dimensions of the ro
12、lling tracks may be limited to the useful zones for this type(s) of vehicle. 3.12 lateral deviation: Tangent, expressed in per cent of the lateral angle with regard to the vehicle di- 4.3 The rolling tracks shall be sufficiently level in rectionll order not to deviate from the reference planea by mo
13、re than the following tolerances (see figure 2): 4 Test area floor - over a length of 2 m, the floor may not be lower than 4 mm under the reference plane, 4.1 The test area floor is composed of two rolling tracks which are clearly indicated on the floor. In the case of use for symmetrical three-whee
14、led ve- hicles, the test area floor will need a central rolling track for the third wheel. - beyond 2 m, the floor has to be situated between two limiting planes opening out in the form of a wedge with gradients of 2 mm/m. The slope of the reference plane (longitudinally as well as laterally) may no
15、t exceed 1 %. 4.2 The rolling track minimum dimensions shall be as follows (see figure 1): 4.4 The rigidity of the rolling tracks shall be suf- ficient to ensure that they stay within the tolerances when the heaviest vehicles are placed on the test area floor. Dimensions in metres 0.9 max. 8.5 min.
16、(6 min. for cars) Figure 1 - Test area floor dimensions 1) Inclinations and lateral deviations of light rays emitted by a headlamp can be measured directly on the aiming screen with regard to the reference point: for example, at 10 m in front of the headlamp, 1 % corresponds to a distance of 0.1 m o
17、n the screen. 2) The reference plane can, for example, be made of straight sections of 2 m placed on the first part of the rolling tracks and adjusted to have the same slope. The tolerance of 4 mm can thus be checked easily by 4 mm gauges. 2 Copyright International Organization for Standardization P

19、icle and fill the fuel tank to attain the complete vehicle kerb mass as specified in IS0 1176. Except for semi-trailers, disconnect any trailer. Remove any excessive accumulation of mud, snow or ice which could affect the vehicle attitude. Check that the headlamps are clean and dry. Seat a driver of
20、 approximately 75 kg on the drivers seat. Check the tyres and inflate them to the pressure pre- scribed by the vehicle manufacturer for normal driving conditions on the road. For vehicles in public or commercial use that have cargo that is generally located in the vehicle when driven, the vehicle sh
21、ould be left with this cargo in its normal location in the vehicle. 5.2 Bring vehicles with pneumatic suspension and seat corrector to the normal road position. Set any levelling device to the “0-position. Reference plane 1 % max. Horizontal plane Drive the vehicle on to the test area floor and brin

23、b) cl The reflectivity shall be sufficient and the ambient lighting low enough to be able to observe the lu- minous beams on the screen clearly. The distance in front of the headlamp shall be at least 7,5 m, the most practical distance being 10 m because a 1 % inclination then corresponds to 0,l m o
24、n the screen. The screen height shall be at least I,5 m and its width at least 3 m for a fixed screen at 10 m; movable screens can be smaller but at least 0,6 m by I,8 m. 6.2 Clearly indicate either the intersection with the reference plane or a line parallel to it with the indi- cation of its heigh
