Company and product certifications


IS certification, created in 2012 as part of the Institut de Soudure association, contributes to the certification of your welding products (application of EN 15085-2 standards for rail components, EN 1090-1 for metal structures and EN ISO 3834 for other activities)

In many cases, these certifications have become essential passports for any company wishing to become a supplier of the leading international customers.

IS Certification has already issued certification of the welding organisations of more than 70 companies in France and abroad.

Our organisation was created more specifically to meet the need for transparency, impartiality and confidentiality required by the new EN ISO/CEI 17065 standard. These measures for example include the letter of undertaking by the auditors, the Certification Committee and the Impartiality Committee.
