本文件描述了光谱辐射测量仪器和程序的要求和建议，包括颜色性能、光谱辐照度、光谱辐射度和光谱总辐射通量（以相对或绝对单位表示）的要求和建议。光谱范围约为200 nm至1700 nm，其中光源、视觉显示器和发光二极管发出的光的表征是最常见的。

This document describes the requirements and recommendations of the instruments and procedures for spectroradiometric measurements, including those of color performance, spectral irradiance, spectral radiance, and spectral total radiant flux, either in relative or absolute units. The spectral range is from approximately 200 nm to 1,700 nm, where the characterization of light from light sources, visual displays, and light emitting diodes is most commonly done.
