本批准方法描述了在60 Hz交流电路和高频条件下（参考高频电路在25 kHz下工作）在标准条件下获得荧光灯电气和光度特性的均匀和可再现测量时应遵循的程序和注意事项。除线性荧光灯外，本文件还涵盖所有U形和圆形荧光灯。

This Approved Method describes the procedures to be followed and the precautions to be observed in obtaining uniform and reproducible measurements of the electrical and photometric characteristics of fluorescent lamps under standard conditions in 60-Hz alternating current circuits and under high-frequency conditions (reference high-frequency circuits are operated at 25 kHz). In addition to linear fluorescent lamps, this document covers all U- and circular-shaped fluorescent lamps.
