Common use of Test conditions Clause in Contracts

Test conditions. 4.7.1. All measurements, photometric and colorimetric, shall be made: 4.7.1.1. In case of a lamp with replaceable light source, if not supplied by an electronic light source control gear or a variable intensity control, with an uncoloured or coloured standard light source of the category prescribed for the device, supplied with the voltage: (a) In the case of filament light source(s), that is necessary to produce the reference luminous flux required for that category of filament light source; (b) In the case of LED light source(s) of 6.75 V, 13.5 V or 28.0 V; the luminous flux value produced shall be corrected. The correction factor is the ratio between the objective luminous flux and the value of the luminous flux found at the voltage applied. 4.7.1.2. In the case of a light source, which is operated independently from vehicle supply voltage and fully controlled by the system, or in the case of a light source supplied by a special power supply, the test voltage as specified by the applicant shall be applied to the input terminals of the light source or 6.75 V, 13.5 V or 28.0 V shall be applied to the input terminals of that system/power supply. The test laboratory may require from the manufacturer this special power supply needed to supply the light sources. 4.7.1.3. In the case of a lamp equipped with non-replaceable light sources (filament light sources and other), with the light sources present in the lamp. 4.7.1.3.1. If operating directly under vehicle voltage system conditions all measurements on lamps equipped with non-replaceable light sources shall be made at 6.75 V, 13.5 V or 28.0 V, or at a voltage as specified by the applicant with respect to any other vehicle voltage system. 4.7.1.3.2. If operated independently from vehicle supply voltage and fully controlled by the system, or in the case of a light source supplied by a special power supply, the test voltage as specified in paragraph 4. 7.1.3.1. shall be applied to the input terminals of that system/power supply. The test laboratory may require from the manufacturer this special power supply needed to supply the light sources. 4.7.1.4. In the case of a system that uses an electronic light source control gear or a variable intensity control, being part of the lamp applying at the input terminals of the lamp the voltage declared by the manufacturer or, if not indicated, 6.75 V, 13.5 V or 28.0 V respectively. 4.7.1.5. In the case of a system that uses an electronic light source control gear or a variable intensity control, not being part of the lamp the voltage declared by the manufacturer shall be applied to the input terminals of the lamp. 4.7.2. However, in the case of light sources operated by a variable intensity control to obtain variable luminous intensity, photometric measurements shall be performed according to the applicant’s description. 4.7.3. The test laboratory shall require from the manufacturer the light source control gear or a variable intensity control needed to supply the light source and the applicable functions. 4.7.4. The voltage to be applied to the lamp shall be noted in the communication form in Annex 1. 4.7.5. The limits of the apparent surface in the direction of the reference axis of a light-signalling lamp shall be determined. However, in the case of category 5 and 6 direction indicators, the limits of the light emitting surface shall be determined. This requirement shall not apply to rear-registration plate illuminating lamps. 4.7.6. In the case of a category S3 or S4 stop lamp, which is intended to be mounted inside the vehicle a sample plate or sample plates (in case of different possibilities) as supplied (see paragraph 3.

Test conditions. 4.7.1. All measurements, photometric and colorimetric, shall be made: 4.7.1.1. In case of a lamp with replaceable light source, if not supplied by an electronic light source control gear or a variable intensity control, with an uncoloured or coloured standard filament light source of the category prescribed for the devicelamp, supplied with the voltage: (a) In the case of filament light source(s), that is voltage necessary to produce the reference luminous flux required for that category of filament light source; (b) In the case of LED light source(s) of 6.75 V, 13.5 V or 28.0 V; the luminous flux value produced shall be corrected. The correction factor is the ratio between the objective luminous flux and the value of the luminous flux found at the voltage applied., 4.7.1.2. In the case of a light source, which is operated independently from vehicle supply voltage and fully controlled by the system, or in the case of a light source supplied by a special power supply, the test voltage as specified by the applicant shall be applied to the input terminals of the light source or 6.75 V, 13.5 V or 28.0 V shall be applied to the input terminals of that system/power supply. The test laboratory may require from the manufacturer this special power supply needed to supply the light sources. 4.7.1.3. In the case of a lamp equipped with non-replaceable light sources (filament light sources and other), with the light sources present in the lamp. 4.7.1.3.1. If operating directly under vehicle voltage system conditions all conditions: All measurements on lamps equipped with non-replaceable light sources shall be made at 6.75 V, 13.5 V or 28.0 V, or at a voltage as specified by the applicant with respect to any other vehicle voltage system. 4.7.1.3.2. If operated independently from vehicle supply voltage and fully controlled by the system, or in the case of a light source supplied by a special power supply, the test voltage as specified in paragraph 43.7. 7.1.3.11.3.1. of this UN Regulation shall be applied to the input terminals of that system/power supply. The test laboratory may require from the manufacturer this special power supply needed to supply the light sources. 4.7.1.4. In the case of a system that uses an electronic light source control gear or a variable intensity control, being part of the lamp applying at the input terminals of the lamp the voltage declared by the manufacturer or, if not indicated, 6.75 V, 13.5 V or 28.0 V respectively. 4.7.1.5. In the case of a system that uses an electronic light source control gear or a variable intensity control, not being part of the lamp the voltage declared by the manufacturer shall be applied to the input terminals of the lamp. 4.7.2. However, in the case of light sources operated by a variable intensity control to obtain variable luminous intensity, photometric measurements shall be performed according to the applicant’s description. 4.7.3. The test laboratory shall require from the manufacturer the light source control gear or a variable intensity control needed to supply the light source and the applicable functions. 4.7.4. The voltage to be applied to the lamp shall be noted in the communication form in Annex 11 to this UN Regulation. 4.7.5. The limits of the apparent surface in the direction of the reference axis of a light-signalling lamp shall be determined. 4.7.5.1. However, in the case where a lamp is intended to be installed at a mounting height (reference axis specified by the manufacturer) of category 5 and 6 direction indicatorsequal to or less than 750 mm above the ground, the limits photometric intensity is verified only up to an angle of the light emitting surface shall be determined. This requirement shall not apply to rear-registration plate illuminating lamps5° downwards. 4.7.6. In the case of a category S3 or S4 stop lamp, which is intended to be mounted inside the vehicle a sample plate or sample plates (in case of different possibilities) as supplied (see paragraph 32. 1.4.6. of this UN Regulation) shall be positioned in front of the lamp to be tested, in the geometrical position(s) as described in the application drawing(s) (see paragraph 2.1.3.1. of this UN Regulation).
