Significance and Use
4.2 Determining torque required to seal a given gasket is also part of this test method. By converting the torque at sealing to total bolt load, useful design information may be obtained for other standard and nonstandard openings.
4.3 This test method may be used as an incoming quality control test to evaluate similar gaskets from different suppliers. This test method may also be used as a quality control test when parameters are agreed upon between the producer and the user.
1.1 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.
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. For specific precautionary statements, see Section 6.
