A Mill Test Certificate (MTC), or Mill Test Report (MTR), is issued by a manufacturer to certify the chemical and mechanical features of a product and its compliance to the applicable norms and technical specifications. Typically, Mill Test Certificates conform to the EN 10204 standard and are related to steel products.

A mill test certificate to EN 10204 shows, generally, the following information:

Type of certificate and standard (example EN 10204 3.1 or EN 10204 3.2)
Manufacturer name
Product name and dimensions
Quantity covered by the certificate (example: tons, with heat numbers)
Heat numbers and batch number (physically shown on the product as well)
Final test result
Dimensional measurements, to check compliance with allowed tolerances (example, for steel pipes: diameter, wall thickness, length, straightness)
Material grade and applicable specification, including results of chemical and mechanical tests
Results of additional tests, like hydrostatic, ultrasounds (UT), hardness, impact test, magnetic particles, metal graphic result etc.
Addenda useful to appraise the full features of the product.
