Formerly under the jurisdiction of Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants, this test method was withdrawn in May 2025. This standard is being withdrawn without replacement because there was no response from industry indicating the method is in use when probed in early 2024 by email to the subcommittee and wax PTP participants. There has been no revision in over 35 years.

5.1 The coefficient of friction is related to the slip properties of many commercial articles that have been coated with petroleum wax (for example, butter cartons and wax-impregnated or hot melt coated corrugated board).

1.1 This test method covers the determination of the coefficient of kinetic friction for a petroleum wax coating or wax-based hot melt coating when sliding over itself.

1.2 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 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.
