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

1.1This 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.

1.2The 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.

1.3This 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.

1.4This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
