【国外标准】 Standard Test Method for Testing of Pipe Thread Sealants on Pipe Tees

5.1 Many of the tests that have been employed in the past to evaluate thread sealant products have not consistently targeted the most significant product features of a thread sealant. For instance, one of a thread sealant's primary performance features is its ability to maintain a seal under a range of conditions. The procedures in this test method assess the important characteristic properties of a thread sealant.5.2 Because of the variability of the test specimens and the techniques employed by each operator, the assembly and test procedures and the testing apparatus have been designed to reduce the variability of the test results.1.1 This test method covers procedures used to assemble, evaluate and test pipe thread sealants.1.2 Test procedures included in this test method are cure speed versus temperature, primer cure, instant seal/sealability, heat aging, solvent resistance, hot strength, steam resistance, and specimen preparation for high pressure testing.1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
