ASTM C681-14
(Test Method)Standard Test Method for Volatility of Oil- and Resin-Based, Knife-Grade, Channel Glazing Compounds
Standard Test Method for Volatility of Oil- and Resin-Based, Knife-Grade, Channel Glazing Compounds
SIGNIFICANCE AND USE
5.1 This test method provides a guide as to the amount of volatile matter that will be emitted from a channel glazing compound when tested by this test method.
SCOPE
1.1 This test method describes the determination of the volatility of oil- and resin-based, knife-grade, channel glazing compounds.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 The subcommittee with jurisdiction is not aware of any similar ISO standard.
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.
