|Publication Date:||10 November 2000|
|ICS Code (Thermoplastic materials):||83.080.20|
1.1 This practice covers the determination of the color stability of a hydrocarbon resin by exposure to a specific temperature for a defined time period in a forced draft oven.
1.2 Color stability is measured by the change in color of the test resin, measured via the yellowness index color scale, in accordance with Practice E 313, or the procedure for Gardner Color, Test Method D 6166.
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.4 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.
