1.1本标准描述了目视测定透明绝缘液体颜色的试验方法。 1.2以可接受的公制单位表示的值应视为标准。 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====== 颜色主要作为电绝缘液体污染的指标。这种污染通常是相关设备中溶剂作用的结果，或者可能表明可能存在污染。 颜色与液体的物理和电气特性之间无法建立明确的关系；因此，颜色本身作为条件的衡量标准具有有限的价值。为了更精确地测定颜色，可使用试验方法D 1209。

1.1 This standard describes a test method for the visual determination of the color of clear insulating liquids. 1.2 The values stated in acceptable metric units are to be regarded as the 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 ====== Color is significant chiefly as an indicator of contamination in electrical insulating liquids. Frequently this contamination is the result of solvent action in the apparatus involved or it may indicate possible contamination. No definite relationship can be established between color and the physical and electrical characteristics of the liquid; for that reason color in itself has limited value as a measure of condition. For more precise determination of color, Test Method D 1209 may be used.
