Company Certification

Company Certification enables organisations to demonstrate, product and/or process, compliance with national and international standards and regulations. TWI Certification Ltd (TWI CL) is accredited by the United Kingdom Accreditation Service (UKAS) to ISO/IEC 17065: Conformity Assessment - Requirements for bodies certifying products, processes and services.

Companies certified by TWI CL have seen changes in their success and profitability worldwide as our products enable them to show compliance with European and International product standards.

Under its ISO/IEC 17065 accreditation, and in accordance with international standards, TWI CL provides certification through its Welding Fabricator Certification Scheme (ISO 3834), Conformity Assessment of the Execution of Steel and Aluminium Structures scheme (EN 1090), and Certification for Welding of Railway Vehicles and Components Scheme (EN 15085).

Recently added to its product portfolio is its Certification of Manufacture of Special Materials Scheme (CMSM), which provides certification in accordance with ISO 17782 (and NORSOK M-650). A recent addition, but one of importance as it demonstrates the competence and capability of a manufacturer to produce a type of product, operate manufacturing processes, and/or work with various materials.

Our Certification Scheme for Welding Training Organisations (CSWTO) enables Further Education and Training Providers, to demonstrate the high standard of welding and fabrication training and development available and for those particularly capable, provide welder assessments as a CSWIP Approved Welder Examination Venue.
