Steel structures — Structural bolting — Test method to determine parameters of bolt tightening proce...
This test method is to be used only if no rules and parameters for tightening exist, e.g. for pretensioning of stainless steel bolting assemblies, or when bolts are pretensioned by turning the head.
This test method establishes a bolt tightening qualification procedure (BTQP) which provides design and execution rules for pretensioning of stainless steel and carbon steel bolting assemblies with…
