MTC IN EN 10204.3

EN10204:2004 is for metallic products-and this norm tell us things about Types of inspection documents. There are no material standards. Mostly material is defined with its chemical composition and mechanical properties in a public standars like ISO, EN, JIS, ASTM etc.

Metallic materials. Types of inspection documents

What is it?

BS EN 10204:2004 is the European standard for inspection documents that authenticate materials used in metallic and non-metallic products. There is increasing pressure for manufacturers to prove that products meet certain chemical and mechanical properties. The documents detailed in BS EN 10204:2004 are a legal and regulatory requirement that must be provided to those purchasing products as proof of quality and product specification.

How does it work?

The standard applies to all metallic products, including plates, sheets, bars, forgings and castings. It may also apply to non-metallic products and is used in conjunction with information about the manufacturing conditions. technical delivery conditions of the manufactured products. Documents required to meet BS EN 10204:2004 include proof of conformity, reports on manufacturing processes, audit reports and technical specifications.

MTC: Mill Test Certificate

EN 10025 is a 6 part European standard relating to hot rolled structural steel.
EN 10025 – Hot rolled products of structural steels refers to a set of european standards which specify the technical delivery conditions for hot rolled products of structural steels. The standard consist of the following parts:
EN 10025-1: Part 1: General technical delivery conditions
EN 10025-2: Part 2: Technical delivery conditions for non-alloy structural steels
EN 10025-3: Part 3: Technical delivery conditions for normalized/normalized rolled weldable fine grain structural steels
EN 10025-4: Part 4: Technical delivery conditions for thermomechanical rolled weldable fine grain structural steels
EN 10025-5: Part 5: Technical delivery conditions for structural steels with improved atmospheric corrosion resistance
EN 10025-6: Part 6: Technical delivery conditions for flat products of high yield strength structural steels in the quenched and tempered condition


A mill test certificate can be a steel industry document that is used to certify the manufacturing standards of the products produced by the mill.
It can specify the following:
A recognized Standard specification number such as an ASTM or AISI number (Ex ASTM A106. The ASTM is the American Society for Testing and Materials. This identifies the type of product (sheet, plate, tube, bar, etc.) and the set engineering standards to which it is produced.
An analysis of the elements (%) that make up the content of the mill product. Ie. carbon, nickel, titanium.
Brief description of the goods such as galvanized carbon steel sheet, welded tube, seamless pipe, zinc coated, hot rolled or cold rolled plate, etc.
