ASTM F146-01

Standard Test Methods for Fluid Resistance of Gasket Materials

SCOPE
1.1 These test methods cover the determination of the effect on physical properties of nonmetallic gasketing materials after immersion in test fluids. The types of materials covered are Type 1, Type 2, Type 3, and Type 7 as described in Classification F104. These test methods are not applicable to the testing of vulcanized rubber, a procedure that is described in Test Method D471. It is designed for testing specimens cut from gasketing materials or from finished articles of commerce.  
1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units in parentheses are for information only.
1.3 Refer to the current Material Safety Data Sheet (MSDS) and any precautionary labeling provided by the supplier of any materials referred to in these test methods.
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 and health practices and determine the applicability of regulatory limitations prior to use.
