MATERIAL TESTING REQUIRED FOR STEEL MATERIALS

Testing of steel materials shall be in accordance with the standards given in Table below:

Tests	Materials	Parameters testeda	Standards for reference
Tensile test	Steel plates Hot rolled sections Hollow sections Steel for cold forming Bolts Profiled steel sheets Stud shear connectors	Yield strength Tensile strength Elongation after fracture	BS EN 10002-1:2001
Charpy impact test	Steel plates Hot rolled sections Hollow sections Steel for cold forming	Impact energy	BS EN 10045-1:1990
Hardness test	Bolts Nuts Washers	Brinell hardness Vickers hardness Rockwell hardness	BS EN ISO 6506-1:2005 BS EN ISO 6507-1:2005 BS EN ISO 6508-1:2005
Proof load test	Nuts	Proof load stress	BS EN 20898-2:1994
All-weld metal tests	Welding consumables	Yield strength Tensile strength Elongation after fracture Impact energy	BS EN 1597-1:1997
Chemical analysis	Steel plates Hot rolled sections Hollow sections Steel for cold forming Bolts Profiled steel sheets	Carbon contentb Carbon equivalent valueb Sulphur contentb Phosphorous contentb Othersc	BS EN ISO 14284:2002
a)     To ensure the adequacy of non-certified steel materials, parameters tested shall be in compliance with the relevant material performance requirements given in Section 2. b)     Compared to the limits specified for ladle analysis in Section 2, limits for product analysis shall be:- 0.03 % higher for carbon content; 0.04 % higher for carbon equivalent value; 0.01 % higher for each sulphur and phosphorous content. c)      The content of the following elements shall also be determined and recorded:- silicon, manganese, copper, chromium, molybdenum, nickel, aluminium, niobium, titanium, vanadium, nitrogen and any other element intentionally added.
