This practice may be used to evaluate Classification F 104 gasket materials using saturated steam and standard ASME RF (raised face) flanges. This practice is intended for use as quality control or material comparison tool and should not be used to predict performance.

1. Scope

1.1 This practice provides a means of comparing various nonmetallic flat gasket materials, Classification F 104, in saturated steam service under controlled conditions. While the practice is designed primarily for flat gaskets, it also can be applied to various form-in-place gasket materials upon modification. The practice may be used for quality control or material comparison purposes as agreed upon between producer and user. This practice is consistent with Fluid Sealing Association test method, FSA-NMG-204-02, with regard to fixtures used and procedure.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

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 appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
