Scope

1.1 This test method covers the determination of the blocking point and picking point of petroleum wax.

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.

Significance and Use

Blocking of waxed paper, because of the relatively low temperatures at which it may occur, can be a major problem to the paper-coating industry. For example, when the waxed surfaces in a roll of waxed paper stick together, upon separation the surface films are marred and the glossy finish is destroyed. The wax picking point and the wax blocking point indicate an approximate temperature range at or above which waxed surfaces in contact with each other are likely to cause surface film injury.
