MTL offers material testing certificates in accordance with EN 10204, 3.1 and 3.2.
Companies often need to verify if a material “fit for use” or that it conforms to international specifications. These materials need to meet the requirements that are set out by the material’s specification. Specifications are a means of identifying what a material is and act like “dog tags” to a certain extent.
Should a customer wish to certify a material to a specific grade/specification, the extent of the testing is not up to the customer or the testing laboratory carrying out the tests. The material’s specification will have specific requirements and all of these requirements need to be measured and reported on, to certify this material.
A commonly known material SA 516M Grade 70 has chemical and tensile requirements and as such, to certify an unknown sample, one must carry out a tensile test and chemical spark. There are supplementary requirements for this grade, such as impact properties. Supplementary requirements are tested at the discretion of the customer and must be communicated through to the testing laboratory prior to, or at the time of the order (in writing).
