ASTM D5642-09

Standard Test Method for Sealed Tube Chemical Compatibility Test

SIGNIFICANCE AND USE
This test method is useful for evaluating a combination of materials for potential use in an electrical insulation system.
SCOPE
1.1 This test method covers procedures for evaluating the interaction of electrical insulation components used, or intended to be used, in electrical insulation systems.
1.2 This test method is useful for determining compatibility but additional testing may be required depending upon application.
1.3 This test method may also provide useful information about the behavior of selected insulating materials when compared to a reference value as opposed to a reference system.
1.4 This test method does not cover systems which operate in liquids or gases other than air.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6 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. See also 8.2.4, 8.3.1 and 8.3.2.1
