1.1 本试验方法涵盖卤化有机溶剂及其混合物颜色的目视测量。它适用于50铂钴（Pt-Co）单位或更少的值。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（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。 ====意义和用途====== 2.1 颜色可能表示溶剂的质量，因为任何颜色都是由于污染物的存在。

1.1 This test method covers the visual measurement of the color of halogenated organic solvents and their admixtures. It is valid for values of 50 platinum-cobalt (Pt-Co) units or less. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of 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. ====== Significance And Use ====== 2.1 Color may be indicative of the quality of the solvent because any color present is due to the presence of contaminants.
