High-strength structural bolting assemblies for preloading - Part 2: Suitability test for preloading

Test for verifying the suitability of high-strength structural bolting assemblies for preloading.

This European Standard specifies a tightening test to verify the suitability of high strength bolt/nut/washer assemblies for preloaded bolted connection in metallic structures. The purpose of this test is to check the behaviour of the fastener assembly so as to ensure that the required preload can be reliably obtained by the tightening methods specified in ENV 1090-1 with sufficient margins against over tightening and against failure.

This European Standard together with BS EN 14399-1:2005, BS EN 14399-3:2005, BS EN 14399-4:2005, BS EN 14399-5:2005 and BS EN 14399-6:2005, supersedes BS 4395-1:1969 and BS 4395-2:1969, which will be declared obsolescent in September 2007, and then, together with BS 449 and BS 5950, will be withdrawn upon publication of Eurocode 3. (BS 4395-1:1969 and BS 4395-2:1969 currently support BS 449 and BS 5950).
