1.1本规程涵盖了获得精确光谱数据以计算物体颜色所需的仪器测量要求、校准程序和材料标准。 1.2本规程列出了在特定方法、规程或规范中需要光谱测量时必须指定的参数。 1.3本规程的大多数章节适用于光谱仪和色度计，前者可以产生光谱数据作为输出，后者原则上类似，但只能产生色度数据作为输出。注意到这种适用性的例外情况。 1.4本规程的范围仅限于仅使用单个单色仪的光谱仪和光谱色度计。本惯例适用于待表征颜色的材料。 1.5 本标准无意解决与其使用相关的安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 This practice covers the instrumental measurement requirements, calibration procedures, and material standards needed to obtain precise spectral data for computing the colors of objects. 1.2 This practice lists the parameters that must be specified when spectrometric measurements are required in specific methods, practices, or specifications. 1.3 Most sections of this practice apply to both spectrometers, which can produce spectral data as output, and spectrocolorimeters, which are similar in principle but can produce only colorimetric data as output. Exceptions to this applicability are noted. 1.4 This practice is limited in scope to spectrometers and spectrometric colorimeters that employ only a single monochromator. This practice is general as to the materials to be characterized for color. 1.5 This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
