welding quality management systems (ISO 3834)

TEC EUROLAB

what does the UNI EN ISO 3834 product scheme consist of and what can TEC Eurolab’s Certification Body do in this context?

TEC Eurolab is accredited by the Italian Accreditation Body (ACCREDIA) for the UNI EN ISO 3834 product scheme.

This certification is complemented by specific services in the field of welding, materials and processes, enabling our Certification Body to offer a complete service to companies in the engineering sector.

ISO 3834 provides a method for demonstrating a manufacturer’s ability to manufacture products of specified quality and, in addition, incorporates other different product and personnel certifications depending on the level required:

welding personnel certification according to ISO 9606-1 and/or ISO 14732
certification of welding co-ordinator according to ISO 14731
certification of non-destructive testing personnel according to ISO 9712
certification of welding procedures according to ISO 15614

ISO 3834 provides a general framework on the criteria to be considered when selecting the appropriate level of quality requirements for fusion welding of metallic materials, from among the three levels specified in:

ISO 3834-2: extended quality requirements
ISO 3834-3: normal quality requirements
ISO 3834-4: elementary quality requirements

A manufacturer who demonstrates conformity to a particular quality level is deemed to have achieved conformity to all lower levels without further demonstration.
