ASTM D3344 Standard Test Method for Total Wax Content of Corrugated Paperboard
1. Scope
1.1 This test method covers the determination of the weight of wax that is present in a specimen of wax-treated corrugated paperboard. The test method is applicable to specimens that have been waxed by either impregnation (saturation) operations or coating operations, or combinations of such operations.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 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. For precautionary statement, see 5.4 and 7.2.
2. Terminology
2.1 Definitions:
2.1.1 weight of applied wax coating - the weight of wax that has been applied to the corrugated board as a coating, expressed as weight per unit area, usually grams of coating per square metre or pounds of coating per thousand square feet of board covered.
NOTE 1 - When it is known that a wax-coated specimen has no impregnating wax present, this extraction procedure is normally calculated to express the data as "weight of applied wax coating".
2.1.2 weight percent wax content - the weight percent of wax present in and on corrugated board relative to the weight of unwaxed board substrate measured at 23 °C (73 °F) and 50 % relative humidity.
