ASTM F146-12
(Test Method)Standard Test Methods for Fluid Resistance of Gasket Materials
Standard Test Methods for Fluid Resistance of Gasket Materials
SIGNIFICANCE AND USE
4.1 These test methods provide a standardized procedure to measure the effect of immersion in specified fluids under definite conditions of time and temperature. The results of these test methods are not intended to give any direct correlation with service conditions in view of the wide variations in temperature and special uses encountered in gasket applications. The specific test fluids and test conditions outlined were selected as typical for purposes of comparing different materials and can be used as a routine test when agreed upon between the purchaser and the manufacturer.
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. These test methods may also be used as a pre-treatment for Multi-Layer Steel, MLS, or Metal Layer Gasket materials adhesion testing per Test Method D3359. The pre-treatment of MLS or Metal Layer Gasket materials pertains only as a pre-cursor to the adhesion test. Other physical property tests described in this standard are not applicable to MLS or Metal Layer Gasket materials.
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.

3. Summary of Test Methods
3.1 Appropriate test specimens are subjected to complete immersion in test fluids. After immersing the specimens in the various
test fluids, the effect on physical properties is expressed as change in tensile strength, compressibility in softened condition,
flexibility, volume change, and thickness and weight changes from the original condition.
