Measured and recorded photometric characteristics Clause Samples
The "Measured and recorded photometric characteristics" clause defines the requirement for documenting and verifying the light-related properties of a product or system. In practice, this clause mandates that specific photometric data—such as luminous flux, intensity, color temperature, or distribution—must be measured using standardized methods and accurately recorded for reference. This ensures that the product meets specified performance criteria and provides a reliable basis for quality control, compliance, and comparison, ultimately solving the problem of ambiguity or inconsistency in lighting performance claims.
Measured and recorded photometric characteristics. The sampled lamp shall be subjected to photometric measurements for the minimum values at the points listed in Annex 4 and the chromaticity coordinates listed in Annex 5, provided for in the Regulation.
Measured and recorded photometric characteristics. The sampled headlamp shall be subjected to photometric measurements at the points provided for in the Regulation, the reading being limited to points Emax, HV 3/, HL, HR 4/ in the case of the driving beam, and to points B 50 L (or R), HV, 50 V, 75 R (or L) and 25 L (or R) in the case of the passing beam (see figure in annex 4).
