Standard Test Method for Sealability of Enveloped Gaskets
 N F112

Annotation

This test method covers the evaluation of the sealing properties of enveloped gaskets for use with corrosion-resistant process equipment.2 Enveloped gaskets are described as gaskets having some corrosion-resistant covering over the internal area normally exposed to the corrosive environment. The shield material may be plastic (such as polytetrafluoroethylene) or metal (such as tantalum). A resilient conformable filler is usually used inside the envelope. The design and construction of nonmetallic gaskets is covered in Practice F336.

The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.

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. For specific precautionary statements, see Section 6.

2 This test method is to be used in place of Test Methods F37, which apply only to single-component gasket materials and are not applicable to envelope-style gaskets.

This fixture may also be used for other gasket materials or designs, with or without modification. Supporting data have been filed at ASTM International Headquarters and may be obtained by requesting Research Report RR:F03-1000.
