ASTM D3235-06

1.1 This test method covers the determination of solvent extractables in petroleum waxes.

1.2 The values given in parentheses are for information only.

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.

1.3 This test method covers the determination of the acceptability of porous filter sticks used for filtration in Test Method D 3235. This method establishes the maximum pore diameter and also provides a means of detecting and measuring changes which occur from continued use.

The solvent extractables in a wax may have significant effects on several of its properties such as strength, hardness, flexibility, scuff resistance, coefficient of friction, coefficient of expansion, melting point, and staining characteristics. Whether these effects are desirable or undesirable depends on the intended use of the wax.
