(Test Method)Standard Test Method for Thickness of Pressure-Sensitive Tapes
Standard Test Method for Thickness of Pressure-Sensitive Tapes
SIGNIFICANCE AND USE
4.1 Thickness is an important property of tapes, and this dimension is important for certain end uses. This test method is useful for quality control and for acceptance testing for conformance to specifications.
SCOPE
1.1 This test method covers the determination of the thickness of pressure-sensitive tapes at standard conditions.
1.2 This test method is intended to replace AFERA 40062 and PSTC 33.2
1.3 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.
1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 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.
