1.1 This test method covers the determination of the weight of wax that has been applied for coating of corrugated board, and the amount of impregnating (saturating) wax in the same facing.

1.2 This test method is especially applicable to board that has a coated surface and also contains wax saturation within the facing structure.

Note 1—The amount of surface wax on board that may or may not contain impregnating (saturating) wax within its structure may be determined alternatively by Test Method D 3521. If it is known that the specimen has coating wax only, with no internal impregnating wax, the total coating wax applied may be determined by Test Method D 3344.

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.
