ASTM D590-93(2002)

1.1 This test method determines quantitatively the total amount of petroleum wax in wax-impregnated papers, including papers referred to as "dry waxed" or simply "waxed" papers, and paper products made from such papers.

1.2 This test method is not intended for use with wax-sized papers, because these generally contain such quantities of rosin or other materials soluble under the conditions of this test method, or both, that the accuracy for quantitatively measuring wax is seriously impaired.

1.3 This test method does not differentiate between "surface wax" and "total wax." It measures the total amount of wax materials extracted under the conditions specified.

1.4 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. Specific precautionary statements are given in Section 8.
