PN-EN ISO 3834-2:2021-09 Quality requirements for welding metallic materials

The PN-EN ISO 3834-2:2021-09 series of standards is intended for organizations that use welding processes in their own products. They contain quality requirements for welding metallic materials, although they can be adapted for other welding processes. They address the quality of products themselves, which may be affected by welding. Three standards are used for certification purposes:
• PN-EN ISO 3834-2:2021, which contains comprehensive quality requirements
• PN-EN ISO 3834-3:2021, which contains standard quality requirements
• PN-EN ISO 3834-4:2021, which contains basic quality requirements

ISO 3834 establishes a method for assessing an organization's ability to produce products of specified quality, regardless of design type. In addition to its universal application, the advantages of the standard include:
• Improved quality of welded products
• Confirmation of competence in the production of welded products
• Facilitated compliance with the requirements of the Pressure Equipment Directive 97/23/EC
