ASTM F147-87(2009)

Standard Test Method for Flexibility of Non-Metallic Gasket Materials

SIGNIFICANCE AND USE
This test method is designed to measure the ability of non-metallic gasket materials to withstand handling, as would be encountered before and during installation of cut gaskets.
SCOPE
1.1 This test method covers the determination of the flexibility of non-metallic gasket materials. It is designed for testing specimens cut from sheet goods or from the gasket in the finished form, as supplied for commercial use. Materials normally classified as rubber compounds are excluded since they are covered in Classification D2000.  
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.
