An increasing requirement in the energy industry is to provide proof that materials meet defined chemical and mechanical properties. This has led to the authentication of material certificate requirements under the standard EN 10204:2004.
EN 10204:2004 has its origin in the German standard DIN 50049, which specified certificate types. These types were adopted when EN 10204 was first published in 1991.
The European Commission revised the standard in 2004 and simplified the range of those certificate types. These are now:
• Type 2.1: Document issued by the manufacturer, stating compliance with the order
• Type 2.2: Test report issued by the manufacturer,
• Type 3.1: Inspection document endorsed by the manufacturer's authorised representative stating compliance with the order
• Type 3.2: Inspection document endorsed by the manufacturer's authorised representative and either an inspection representative named by the purchaser or an independent third-party inspection body
