What is a Type 3.2 certificate? Customer Service

EN 10204:2004 is a European standard for material certificates, of which there are four different types. Type 3.1 certificates are commonly referred to as ‘Mill Certificates’ and confirm the originating production mill plus general mechanical, physical and chemical properties.

Type 3.2 certificates are commonly referred to as ‘Witness Testing’ or ‘3rd Party Inspection’ certificates. By using an outside agency to witness sampling and testing of the material, plus validate copies of the associated paperwork, they provide independent assurance of a material’s properties and greater confidence of its traceability.
