本文件描述了荧光灯可在受控条件下运行的程序，以获得有关单个灯具寿命、光输出变化和灯具寿命期间变化的其他参数的最佳可比数据。它描述了在标准条件下对荧光灯进行寿命试验期间，在获得均匀且可再现的测量值时应遵循的程序和注意事项。它涉及在辅助设备上运行的线性、U形和圆形荧光灯的寿命测试，这些辅助设备的设计和认证符合灯具行业标准和公差。

This document describes the procedures by which fluorescent lamps can be operated under controlled conditions to obtain optimally comparable data on individual lamp life, changes in light output, and other parameters that vary during the life of the lamp. It describes the procedures to be followed and the precautions to be observed in obtaining uniform and reproducible measurements during life testing of fluorescent lamps under standard conditions. It addresses life testing of linear, U-shaped, and circular-shaped fluorescent lamps operated on auxiliary devices designed and certified to meet lamp industry standards and tolerance.
