ASTM D3522 Standard Test Method for Applied Coating Wax and Impregnating (Saturating) Wax in Corrugated Board Facing
1. Scope
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 D3521. 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 D3344.
1.3 This standard does not purport to address all of the safety problems, 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. For specific hazard statements, see Note 4.

3. Terminology
3.1 Definitions:
3.1.1 weight percent impregnating wax - the weight percent of wax in the facing relative to the weight of unwaxed facing measured at 23°C (73°F) and 50 % relative humidity.
3.1.2 weight of applied coating wax - the weight of applied coating per unit area of board, usually grams per square metre or pounds per thousand square feet of board covered.
