1. Scope
1.1 This test method provides a means of determining the degree to which gasket materials under compressive load adhere to metal surfaces. The test conditions described are indicative of those frequently encountered in gasket applica- tions. Test conditions may also be modified in accordance with the needs of specific applications as agreed upon between the user and the producer. The maximum temperature recom- mended for this test method is 205°C (400°F). 1.2 The values stated in SI units are to be regarded as standard. The values 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 appro- priate safety, health, and environmental practices and deter- mine the applicability ofregulatory limitations prior to use. 1.4 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Summary of Test Method
3.1 The procedure described in this test method involves placing a specimen of a gasket material between flat platens of the desired metal, loading the assembly, and subjecting it to a specified set ofconditions. The tensile force required to part the platen is measured in newtons or pounds-force and is recorded along with the calculated stress (force per unit area) in megapascals or pounds-force per square inch ofgasket surface. N OTE 1—This tensile force required to separate the platens may be in excess of 8896 N (2000 lbf). N OTE 2—This fixturing also provides for the measurement of creep relaxation in accordance with Method B of Test Methods F38.
4. Significance and Use
4.1 This test method provides terms such as megapascals or pounds-force per square inch of gasket surface for expressing the extent of adhesion applicable to all materials within the scope of Classification System F104. Under certain conditions, adhesion develops when gasket materials are confined in a compressed state between metal flanges. Adhesion is important as an index ofease ofremoval ofa gasket material. Since other variables may enter into the performance in an application, the results obtained should be correlated with field results. A typical set of conditions is described in this test method. This test method may be used as an acceptance test when agreed upon between the user and the producer.
5. Apparatus
5.1 Circulating Air Oven, capable of maintaining 100 6 2°C (212 6 3.6°F) or other specified temperature as agreed upon between the user and the producer. 5.2 Test Fixture, 3 composed of two platens with holes 180° apart on the side of each platen, a calibrated bolt, washer, nut, (in accordance with the fixture in Test Method B of Test Methods F38) a dial indicator assembly, steel dowel pins, and a steel yoke or similar device to grip the dowel pins. The yoke, in turn, is attached to the grips of a test machine that will provide the capability of applying a tensile force perpendicular to the plane of the platen surface. See Fig. 1. Standard platen surface is smooth (as obtained using 8/0 dry garnet paper, refer to section 6.2), however, other surface finishes may be speci- fied as agreed upon between the user and the producer.
