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.
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.
