The National Structural Steelwork Specification (NSSS) is a specification prepared by all sections of the steelwork industry that can be incorporated into all forms of contract covering the technical aspects of structural steelwork in buildings. The 5th edition of the NSSS was prompted by the development of the forthcoming European standard for the fabrication and erection of structural steelwork, BS EN1090-2. It is a halfway house between version 4 of the NSSS and this new European standard. The changes include updating the reference standards for bolts and welding,aligning the tolerances with the National Structural Concrete Specification, a reference to the welding quality standard BS EN ISO 2834-3 and by reference the welding coordination standard BS EN ISO 14731, a new section giving options for post-galvanising inspection to avoid Liquid Metal Assisted Cracking, a new Annex giving practical advice on the visual inspection of welds and a revision of the hold times in Annex AISBN: 0 85073 052 X
