ASTM D 3521:1986

1.1 This test method covers determination of the weight of wax that is present as a coating on the surface of corrugated board. This method is applicable to board to which wax has been applied by curtain coating, roll coating, or other methods; the substrate board may or may not contain impregnating (saturating) wax within its structure. Note 1 - If it is known that the specimen has coating wax only, with no internal saturating wax, the total coating wax applied may be determined by Test Method D 3344. 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.
