(Practice)Standard Practice for Coating/Adhesive Weight Determination
Standard Practice for Coating/Adhesive Weight Determination
SIGNIFICANCE AND USE
5.1 Coating weight is an indicator of certain functional characteristics of coated substrates (for example, sealability, peelability, appearance). The methodology described in this practice is a means of determining coat weight.
5.2 This practice does not address acceptability criteria. These need to be jointly determined by the user and producer of the product.
5.3 The methodology described in this practice includes operator assessment of effective coating removal. This is a subjective assessment and requires operator training for consistent results.
5.4 This practice is applicable to coated substrates in which only the coating is soluble in the chosen solvent. The solvent used is critical to the success of the coating removal process. The coated substrate manufacturer must provide guidance in choice of solvent.
SCOPE
1.1 This practice covers a procedure for determining the amount of coating applied to a substrate, (for example, film, paper, nonwoven). The amount of coating is expressed as a weight per given area, (for example, g/m2, lb/ream).
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
