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.
