ActiveMechanical properties of fasteners--Preloading test for the detection of hydrogen embrittlement--Parallel bearing surface method
紧固件机械性能 检查氢脆用预载荷试验 平行支承面法
Application Summary AI generated
This standard specifies a preloading test method using parallel bearing surfaces to detect hydrogen embrittlement in fasteners. It is applied in quality control and material testing for bolts, screws, and studs, particularly in industries like automotive, aerospace, and construction where high-strength fasteners are used. The test ensures that fasteners subjected to plating or coating processes do not fail prematurely due to hydrogen-induced cracking.
