EN 10204 defines four types of inspection documents for metallic products, but only 3.1 and 3.2 matter for titanium procurement. A 3.1 certificate means the manufacturer own inspection department tested the material and certifies compliance with actual chemical and mechanical values traceable to the heat number. The manufacturer takes full legal responsibility. 90% of all titanium orders use 3.1, the industry standard for chemical processing, marine, automotive, and industrial applications. A 3.2 certificate includes everything in 3.1 plus verification by an independent third-party inspector who witnesses the testing and co-signs the certificate. Common agencies include SGS, Bureau Veritas, TUV, DNV. 3.2 is mandatory for aerospace, nuclear, North Sea NORSOK projects. It adds $500-1500 and 3-7 days lead time. Common mistakes: ordering 3.2 when 3.1 is sufficient, accepting 3.1 when 3.2 was specified, confusing third-party lab testing with witnessed 3.2 inspection. Ylasting Titanium provides EN 10204 3.1 certificates as standard on every shipment at no extra cost. 3.2 inspection available on request. Contact us for certification requirements.
