The United Kingdom Accreditation Service (UKAS) has recently awarded TWI Certification Ltd with status to carry out conformity assessment for steelwork manufacturing companies under the Construction Products Directive. With the new scope, TWI Certification is able to offer accreditation to ISO 3834 (Quality Requirements for Fusion Welding) and Factory Production Control (FPC), helping companies to gain the CE mark for their products.
Following assessment by UKAS and a subsequent recommendation to the Secretary of State for Business, Innovation and Skills, TWI Certification has been notified to the European Commission and other Member States as a body fulfilling requirements to carry out conformity assessment according to the Construction Products Directive (EN1090-1). The new status means that the company is able to offer a complete audit of welding operations associated with production of structural steelwork.
With full implementation of the EU Construction Product Regulation due in July 2013, manufacturing companies will be required to CE mark all steelwork produced for the construction industry. �The CE mark demonstrates compliance with the Construction Products Directive, meeting the minimum requirements of EU and EFTA member states and acting a 'passport' for a company to legally place their products on the construction market in all member states.
The route to achieving a CE mark involves a Factory Production Control (FPC) system audit of welding operations associated with production, which must be certified by an independent organisation or nominated body such as TWI Certification. The certification body will check that a manufacturer's welded construction products meet the technical requirements of BS EN 1090-2,(steel) and/or BS EN 1090-3 (aluminium).
The FPC system for structural steelwork is similar to the BS EN ISO 9001 Quality Management System but requires that a nominated welding coordinator is responsible for all welding activities, and that the manufacturing company keeps a documented Welding Quality Management System�meeting the requirements of ISO 3834. �
The Welding Quality Management System will group a company's products under four Execution Classes - Class 1 for farm buildings, Class 2 for other buildings, Class 3 for regular bridges, and Class 4 for nuclear power stations or long-span bridges. Each category has varying levels of quality and welding related requirements for compliance.
