本文件描述了在60 Hz交流电（AC）电路中，在标准条件下，对高强度气体放电灯（HID）的电气和光度特性进行均匀且可重复测量时应遵循的程序和注意事项。本文件涵盖的HID灯包括一般照明应用中使用的灯组，通常称为汞蒸气、金属卤化物和高压钠。通常需要的光度信息是一个或多个方向上的总光通量（流明）和/或发光强度（坎德拉）以及颜色。通常测量的电气特性包括线电压、灯电压、灯电流和灯功率。

This document 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 high intensity discharge (HID) lamps under standard conditions in alternating current (AC) circuits at 60 Hz. The HID lamps covered by this document include the lamp groups commonly known as mercury vapor, metal halide, and high pressure sodium used in general lighting applications. The photometric information usually required is total luminous flux (lumens) and/or luminous intensity (candelas) in one or more directions, and color. The electrical characteristics usually measured are line voltage, lamp voltage, lamp current, and lamp power.
