Welding Fabrication Standards Page 10 On the basis of the above stated considerations, EN ISO 3834 should be referred to both as a system and a process standard, as it also identifies quality management requirements to obtain adequate control of the manufacturing process (e.g. the welding fabrication activities). In the chapter 2 the ISO 3834 - 2 requirements will be explained in detail ,giving practical guidance on the application and use, while in chapter 3 the differences from part 2, 3 and 4 will be outlined, and guidance is given on their selection criteria. 1.3 EWF Certification scheme for EN ISO 3834 The European Federation for Welding, Joining and Cutting (EWF), by virtue of its unique international expertise has developed a high integrity and specialised certification system to assure companies’ compliance with EN ISO 3834. Great care has been taken to detail the interpretation of the standard in terms of third party assessment, to specify and register properly trained scheme assessors, and to devise an operational structure so that certification of companies will be consistent wherever the scheme rules are applied. This is done by appointing one organisation in each country to act for EWF, and these organisations are assessed and monitored against Rules provided by EWF itself. These organisations are known as the EWF Authorised National Bodies for Company Certification (ANBCCs), and are responsible for ensuring that the standards of assessment and certification are maintained. In this, the objective is that EWF certified companies will have demonstrated that they have achieved an identified, minimum level of capability over a specified scope of activity, irrespective of the country in which they had been qualified. 1.3.1 The EWF ISO 3834 Certificate and Schedule The primary intention of EN ISO 3834 certification is to ensure that manufacturers are competent and exercise adequate control of the special process of welding so that customers or others may have confidence that the welded products they produce will comply with the regulatory and/or contractual requirements. Moreover, in the field of quality management in fabrication, the European trend is clearly moving toward a product/process approach. The European Directives and their supporting European harmonised standards (requiring the fulfilment of specific technical requirements, typical of any merchandise sector) are exhaustive examples of that. In order to help Companies in the fulfilment of such requirements, consistently to the product manufactured, EWF have produced specific supplementary guides for the processes/products considered (e.g. railway components, pressure vessels, construction products), taking into consideration the applicable standards (also considered in this book) and the best practice manufacturing procedures, already shared by the main European Manufacturers and Customers.

Welding Fabrication Standards Page 11 In order to give evidence of such specific technical capabilities of Manufacturers, the EWF Certificate, where the references, against which the certification has been got, are reported together with the issue and expiry date of the Certificate itself and the Company’s data, is supplemented with a Schedule, where technical information (reference standards, materials, welding processes, supplementary requirements, deviations, etc.) on the fabrication process adopted and the welded products manufactured is detailed and the name of the responsible welding co-ordinator reported. Therefore the advantages for the Manufacturers in getting a certification against the EWF ISO 3834 Certification Scheme, can be summarised as follows: − welded products are differently treated according to the specificity of their welding fabrication process; − manufacturers are guided to satisfy harmonised European Directives’ requirements through implementation of the Scheme; − the specific areas of competence (for Personnel and Companies) are explicitly encompassed and registered in the Schedule; − manufacturers can get visibility through the Register (www.ewf.be) of certified Companies. 1.3.2 The Integrated Management Certification System EWF realised also a certification Scheme dealing with the environmental management in welding fabrication, having as a basis the EN ISO 14001 (Environmental management systems- Specification with guidance for use) and its EWF interpretations toward welding and allied processes. The result of that has been the EWF Environment Management Scheme (EWF – EMS). More recently, a third Scheme has been introduced, related to health and safety management in welding and allied processes. The starting reference document has been the BSI 8800 (Guide to occupational heath and safety management system), interpreted and fitted on the specific technological operations, resulting in the EWF Safety Management Scheme (EWF – SMS). It’s anyway unquestionable that a Manufacturer can control the Environment, Health and Safety aspects of his welding fabrication process only if the welding and allied activities are already properly controlled from the production point of view, that is through implementation of the EWF EN ISO 3834 Scheme. The result of such an approach is the possibility for Companies to adopt the comprehensive EWF Integrated Manufacturer Certification System (EWF IMCS), covering all the management aspects in welding fabrication, that is: quality, environment and heath & safety.
