(Test Method)Standard Test Method for Total Wax Content of Corrugated Paperboard
Standard Test Method for Total Wax Content of Corrugated Paperboard
SIGNIFICANCE AND USE
Many of the functional properties of wax-treated corrugated paperboard and cartons are dependent on the amount of wax present.
In the case of wax-saturated, or wax-impregnated, paperboard the principal concern is with the weight of wax used relative to the weight of paperboard present, that is, the weight percent content or pickup. In some applications the saturating wax may be deposited in the three elements of the corrugated board in such a way as to individually control the amount in each element, that is, the medium and the two facings.
In the case of wax-coated corrugated paperboard the principal concern is the weight of wax on the board surface per unit area. The functional values of the wax coating as a barrier or a decorative coating are dependent, in part, on the amount of wax in the continuous surface layer, relative to the area covered. The weight of coating relative to the weight of substrate is not usually a concern with regard to product quality.
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.
