ASTM D6396-99 (2020) pdf free.Standard Test Method for Testing of Pipe Thread Sealants on Pipe Tees.
This test method covers procedures used to assemble,evaluate and test pipe thread sealants.
Test procedures included in this test method are curespeed versus temperature， primer cure，instant seal/sealability,heat aging, solvent resistance，hot strength，steam resistance,and specimen preparation for high pressure testing.
The values stated in inchpound units are to be regardedas the standard. The values given in parentheses are forinformation only.
This standard does not purport to address all of thesafety concerns，if any, associated with its use. lt is theresponsibility of the user of this standard to establish appro-priate 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 TechnicalBarriers to Trade (TBT) Committee.
Pipe tee and plug fittings，assembled with the sealantunder test,are subjected to a variety of conditions and testedfor sealability and removal torque,in. cap，coupling andnipple assemblies are prepared with the sealant under test forhigh pressure testing (typically 10 000 psi).Many of the tests that have been employed in the past toevaluate thread sealant products have not consistently targetedthe most significant product features of a thread sealant. Forinstance，one of a thread sealant’s primary performance features is its ability to maintain a seal under a range ofconditions. The procedures in this test method assess theimportant characteristic properties of a thread sealant.
Because of the variability of the test specimens and thetechniques employed by each operator,the assembly and testprocedures and the testing apparatus have been designed toreduce the variability of the test results.ASTM D6396 pdf download.
