PD CEN ISO/TR 3834-6:2007 gives guidelines for the implementation of requirements given in the other parts of BS EN ISO 3834, and is intended to help manufacturers and users select the part of BS EN ISO 3834 appropriate to their needs. It is expected that they will already be familiar with BS EN ISO 3834 series as a whole.
Welding is a special process in that the final result may not be able to be verified by testing. The quality of the weld is manufactured into the product, not inspected. This means that welding normally requires continuous control or that specific procedures be followed, or both. BS EN ISO 3834 deals with quality requirements in welding and has been prepared in order to identify those controls and procedures.
BS EN ISO 3834 is not a quality system standard intended to take the place of ISO 9001, but a useful, additional tool for use when ISO 9001 is applied by manufacturers, in which case the meeting of its requirements needs to be recorded in certificates or documentation. However, BS EN ISO 3834 can be used independently of ISO 9001.
BS EN ISO 3834 is intended for the fusion welding of metallic materials, and its application is independent of the products manufactured. However, its principles and many of its detailed requirements are also relevant for other welding and welding-related processes.
Among other international standards covering resistance welding and thermal spraying are BS EN ISO 14554 and BS EN ISO 14922, respectively.
One of the aims of BS EN ISO 3834 is to define requirements in the field of welding so that contracting parties or regulators do not have to do it themselves. A reference to a particular part of BS EN ISO 3834 should be sufficient to demonstrate the capabilities of the manufacturer to control welding activities for the type of work being done. This concept also applies to committees responsible for drafting product standards.
BS EN ISO 3834 does not in itself require external assessment or certification. However, assessments by customers and certification by independent bodies are growing trends in commercial relations and the standard can serve as a basis for these purposes, as well as for the demonstration of performance by those manufacturers implementing it.
