TEST FOR STABILITY OF PHOTOMETRIC PERFORMANCE Clause Samples

The "Test for Stability of Photometric Performance" clause defines the requirement to verify that a lighting product maintains consistent light output and quality over a specified period or under certain conditions. In practice, this involves subjecting the product to operational or environmental stress—such as extended use, temperature fluctuations, or voltage variations—and measuring its photometric properties before and after the test. This clause ensures that the product will reliably perform as intended throughout its expected lifespan, thereby protecting users from premature degradation and ensuring compliance with performance standards.
TEST FOR STABILITY OF PHOTOMETRIC PERFORMANCE. The tests shall be carried out in a dry and still atmosphere at an ambient temperature of 23°C + 5°C, the complete headlamp being mounted on a base representing the correct installation on the vehicle.

TEST FOR STABILITY OF PHOTOMETRIC PERFORMANCE. 1.1. Clean headlamp The headlamp shall be operated for 12 hours as described in paragraph 1.1.1. and checked as prescribed in paragraph 1.1.2. 1.1.1. Test procedure1 The headlamp shall be operated for a period according to the specified time, so that: (a) In the case where only one lighting function (driving or passing-beam or front fog lamp) is to be approved, the corresponding filament and/or LED module(s) is (are) lit for the prescribed time2; (b) In the case of a headlamp with a passing-beam and one or more driving-beams or in the case of a headlamp with a passing-beam and a front fog lamp: 1 For the test schedule see Annex 8 to this Regulation. 2 When the tested headlamp includes signalling 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 mode with an on/ off time of approximately one to one. (i) The headlamp shall be subjected to the following cycle until the time specified is reached: 15 minutes, principal passing-beam filament or principal passing-beam LED module(s) lit; 5 minutes, all filaments and/or LED module(s) lit. (ii) If the applicant declares that the headlamp is to be used with only the passing-beam lit or only the driving-beam(s) lit3 at a time, the test shall be carried out in accordance with this condition, activating2 successively the passing-beam half of the time and the driving-beam(s) (simultaneously) for half the time specified in paragraph 1.1. above. (c) In the case of a headlamp with a front fog lamp and one or more driving-beams: (i) The headlamp shall be subjected to the following cycle until the time specified is reached: 15 minutes, front fog lamp lit; 5 minutes, all filaments and/or all LED modules lit. (ii) If the applicant declares that the headlamp is to be used with only the front fog lamp lit or only the driving-beam(s) lit3 at a time, the test shall be carried out in accordance with this condition, activating2 successively the front fog lamp half of the time and the driving-beam(s) (simultaneously) for half the time specified in paragraph 1.1. above. (d) In the case of a headlamp with a passing-beam, one or more driving- beams and a front fog lamp: (i) The headlamp shall be subjected to the following cycle until the time specified is reached: 15 minutes, principal passing-beam filament or principal passing-beam LED module(s) lit; 5 minutes, all filaments and/or all LED modules lit.
