ASTM C1375-00(2005)

Standard Guide for Substrates Used in Testing Building Seals and Sealants

SIGNIFICANCE AND USE
The guide provides recommendations for substrates and methods of surface preparation to be used in comparative tests of building seals and sealants.
SCOPE
1.1 This guide describes the recommended standard substrates and their recommended surface preparation for use in standard tests of building seals and sealants.
1.2 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.
