ASTM D1746-23 PDF

Scope: 1.1 This test method covers the measurement of the transparency of plastic sheeting in terms of regular transmittance (Tr). Although generally applicable to any translucent or transparent material, it is principally intended for use with nominally clear and colorless thin sheeting. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. NOTE 1—There is no known ISO equivalent to this standard. NOTE 2—For additional information, see Terminology E284 and Practice E1164. 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.
