ASTM D3944 Test Method for Solidification Point of Petroleum Wax
1. Scope
1.1 This test method describes a procedure for rapidly determining the solidification point of petroleum wax.
NOTE 1 - This test method is also applicable to similar materials such as synthetic waxes but the precision may vary.
1.2 The values in acceptable metric units are to be regarded as the standard. The values in parentheses are for information only.
1.3 This standard does not purport to address all of the safety problems, 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.
