Historical Standard: ASTM D1746-97 Standard Test Method for Transparency of Plastic Sheeting
SUPERSEDED (see Active link, below)
ASTM D1746
1. 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 and health practices and determine the applicability of regulatory limitations prior to use.
Note 1-There is no similar or equivalent ISO standard.
