ISO 3834 certification: Quality requirements for fusion welding of metallic material

Compliance with  ISO 3834 is now mandatory for welding quality management in harmonised European standards for construction products, pressure vessels, pipework and boilers. One of the key elements of EN ISO 3834 is that it requires the manufacturer to demonstrate the competence of their welding coordinators.

Lloyd’s Register has a long history of certifying welders, welding operations and welding quality procedures according to several international standards, including EN and ISO standards. The technical expertise of our surveyors can help your welding coordinators achieve ISO 3834 certification. 

We offer accreditation to Parts 2, 3, and 4 of the ISO 3834 standard:

  • Part 2 – Comprehensive Quality Requirements
  • Part 3 – Standard Quality Requirements
  • Part 4 – Elementary Quality Requirements
