An increasing requirement in the 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.
What is a true Type 3.2 certification?
An EN 10204 type 3.2 certificate declares the products or material supplied by the manufacturer are in compliance with the requirements of the order order. The certificate is prepared by the manufacturer's authorised inspection representative (such as Lloyd's Register).True EN 10204:2004 Type 3.2 certification is produced by the manufacturer, with test results supplied. The independent third-party inspector will have witnessed the test results and verified the material's identification and traceability through objective evidence.
Certification "to the intent of" Type 3.2
A common practice in the industry is for the purchaser to order material from an intermediate material handler or stockist. That handler may select material that has only been certified by the manufacturer using a Type 3.1 certificate. In the standard, this has not been verified by a third-party inspector.
However, it is widely accepted that material with a Type 3.1 certificate can be "validated" to the intent of Type 3.2. This happens when the material handler uses an independent third-party to validate the material by way of verification tests.
Lloyd's Register can provide "intent-of" Type 3.2 certification by visiting the material handler to identify the material to be verified. This includes:
- Visual examination
- Sample dimensional checks
- Confirmation the material is traceable back to the ladle chemical analysis which may be in the form of a Type 3.1 certificate.
Our surveyor also visits the test house to witness all additional testing of the material necessary to confirm compliance with the specification.
It is important in this instance that the purchaser knows and accepts an "Intent-of" Type 3.2 certificate.
