3 Guide to the CE Marking of Structural Steelwork iii PREFACE PREFACE The CE Marking standard for fabricated structural steelwork, EN : A1:2011 'Execution of steel structures and aluminum structures: Part 1: Requirements for conformity assessment of structural components' has been cited in the European Commission's Official Journal (OJ). The Applicability Date is 1 st of January 2011, followed by a 42 months co-existence period. This means that CE Marking of fabricated steelwork can start and will become mandatory in all EU member and EFTA member states from 1 st of July TC9 is the technical committee within ECCS responsible for making recommendations concerning technical specifications for manufacturing and erection. The committee has prepared this publication to provide practical guidance on the CE Marking of structural steelwork in accordance with the Construction Products Directive (CPD), the Construction Products Regulation (CPR) and the transition period between CPD and CPR. It is hoped that this publication will assist the steelwork contractors, their purchasing clients and supply chain including stockholders, part fabricated products (curved steel), proprietary products (purlins, cellular beams etc.) designers, specifiers and construction managers.
