Standard Test Method for Oil Content of Petroleum Waxes
ORDER

Scope

1.1 This test method covers the determination of oil in petroleum waxes having a congealing point of 30 °C (86 °F) or higher as determined in accordance with Test Method D938, and containing not more than 15 % of oil.2

Note 1: With some types of waxes, of oil contents greater than 5 %, there may be an incompatibility with MEK resulting in the formation of two liquid phases. If this occurs, the test method is not applicable to the material under test.

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 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.

Significance and Use

4.1 The oil content of 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 oil straining. The importance of these effects may be dependent upon the ultimate use of the wax.
