MTC Checker: check a mill test certificate against the standard.

It reads the certificate type, product, standard, grade, size, heat number, chemical analysis and mechanical test results, then compares each value with the reference range of the claimed grade and marks it within range, close to a limit (within 3 %), or out of range. It also lists the content EN 10204 requires for the stated certificate type, for example the heat number, test results and the authorised inspection representative's validation on a 3.1, and flags values that look like the wrong unit, such as ksi in an MPa column or boron in ppm.

ISO 898-1 property classes 4.6, 5.6, 8.8, 10.9 and 12.9; ISO 3506-1 stainless A2-70, A4-70 and A4-80; ASTM A193 B7, B7M, B8 and B8M (Class 1); A194 2H nuts (hardness); F3125 A325 (up to 1 in) and A490; A307 Grade A; F1554 Grades 36, 55 and 105. ISO 898-2 nut classes 8 and 10 are recognised, but their values are not checked yet. Any other grade is shown as not checked.

The file is sent to an AI provider in the USA only to read the values, through a route that excludes providers which store or train on the content. On our side it is held in memory for the duration of the check and is not stored afterwards, not saved to disk or to our systems, and not used to train AI models. Details are in our privacy policy.

No. It is an aid for reading a certificate quickly, not an inspection, a test or a legal conclusion on conformity. AI can misread a value, and the reference figures are minimums and maximums from the standards, not your order. The governing standard, its current edition and your contract or purchase order prevail; compare every value with the original certificate.
