Luminous intensities Sample Clauses
Luminous intensities. 4.8.3.1. If not otherwise specified, the intensity of light emitted by each of the two samples supplied shall:
(a) On the reference axis (HV), be not less than the minimum specified in the table of the pertinent function in paragraph 5.;
(b) In no direction where the lamp is visible, exceed the maximum, specified in the table of the pertinent function in paragraph 5.;
(c) Outside the reference axis, - be not less than the product of the minimum specified in the table of the pertinent function in paragraph 5., by the percentage specified in the pertinent light distribution figure reproduced in Annex 3 for each direction in question, or - be not less than the intensity value as specified in the pertinent light distribution figure reproduced in Annex 3 for each direction in question;
(d) Within the angles of geometric visibility defined in the tables in Annex 2, be not less than the minimum specified in the table of the pertinent function in paragraph 5. The provisions of the relevant paragraphs of Annex 3 on local variations of intensity shall be observed.
4.8.3.1.1. In addition, in order to verify the visibility of red light towards the front and/or white light towards the rear of a vehicle required in UN Regulation No.48, the applicant may request an additional test, to show that in the angular field from 165° to 180° outboard in horizontal direction and -2.5° to +5° in vertical direction, the maximum intensity is not more than 2.5∙10-1cd. This additional test may be conducted taking into account the influence of the vehicle body.
4.8.3.2. When an assembly of two independent lamps, to be type approved as lamps marked "D" and having the same function, is deemed to be a single lamp, it shall comply with the requirements for:
(a) Maximum intensity if all lamps together are lit;
(b) Minimum intensity if either lamp has failed.
4.8.3.3. An interdependent lamp system shall meet the requirements when all its interdependent lamps are operated together. However:
(a) If the interdependent lamp system providing the rear position lamp is partly mounted on the fixed component and partly mounted on a movable component, the interdependent lamp(s) specified by the applicant shall meet the outboard geometric visibility colorimetric and photometric requirement, at all fixed positions of the movable component(s). In this case, the inboard geometric visibility requirement is deemed to be satisfied if this (these) interdependent lamp(s) still conform to the photometric values ...
