GB/T 22907-2008 in English

《GB/T 22907-2008灯具的光度测试和分布光度学》由TC224（全国照明电器标准化技术委员会）归口，TC224SC3（全国照明电器标准化技术委员会光辐射测量分会）执行，主管部门为中国轻工业联合会。
本标准规定了光度测试的标准条件，并推荐了测试程序，使所确定的灯具光度特性及其陈述报告有足够的准确度和复现性，这些规定为统一国家标准提供基础，并为光度实验室的试验和灯具性能数据的表达提供指导。对于实际测试条件不同于标准测试条件的灯具，标准给出了修正系数的测量要求。

Scope

This standard contains general requirements for photometric testing of most types of luminaires. This standard specifies the standard conditions for photometric testing and recommends testing procedures to ensure that the determined photometric characteristics of lamps and their statement reports have sufficient accuracy and reproducibility. These regulations provide the basis for unifying national standards and provide guidance for photometric experiments. Provides guidance on laboratory testing and presentation of luminaire performance data. For lamps whose actual test conditions are different from the standard test conditions, the standard gives the measurement requirements for the correction coefficient. A detailed description of the photometric method is of utmost importance to laboratory personnel and engineers, but it is equally important to data users. Proper interpretation of data generally depends on a good understanding of the measurement processes involved, and this International Standard also provides the user with an understanding of the photometric procedure and presentation of the data. For special luminaire types involved in very specialized installations, specific recommendations relating to measurement and data presentation requirements are required, the characteristics of which cannot be covered by such general standards, and should be referenced in the appropriate chapters of this standard in a number of supplementary standards, and where necessary Define special requirements and measurement conditions at time. For luminaires not covered by a specific standard, the most appropriate standard and the requirements of this general standard can be used to guide the actual measurement procedure.
