Scope

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 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

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 D1209 may be used.
