(Test Method)Standard Test Method for Corrosion Testing of Gaskets
Standard Test Method for Corrosion Testing of Gaskets
SIGNIFICANCE AND USE
This test method is designed to compare all types of gaskets under simulated field operating conditions. Performance of a gasket can thus be measured prior to the start-up of chemical processes.5 The design of the test unit provides maximum range of corrosion resistance so that meaningful results are possible. This test method may be used as a routine test when agreed upon between the purchaser and the seller.
SCOPE
1.1 This test method covers the evaluation of gaskets under corrosive conditions at varying temperature and pressure levels. The test unit may be glass lined if the flanges are sufficiently plane (industry accepted), thus providing resistance to all chemicals, except hydrofluoric acid, from cryogenic temperatures to 260°C (500°F) at pressures from full vacuum to the allowable pressure rating of the unit, or made of other suitable material. The test unit described (Fig. 1) has an internal design pressure rating of 1034 kPa (150 psi) at 260°C (500°F).
1.2 The values stated in SI units are to be regarded as the standard.
1.3 his 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. For specific hazards statements, see Section 5.
