ASTM D6493-99 - 10.12.1999
 
1. Scope

1.1 These test methods are intended for determining the softening point of hydrocarbon resins and similar materials by means of an automated ring-and-ball apparatus.

1.1.1 The ring and ball softening point of a hydrocarbon resin may be run with lower precision using the manual ring and ball softening point in Test Method E 28.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

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.
