Engineering basis

EN 10204 inspection documents include 2.1, 2.2, 3.1 and 3.2 types. Type 3.1 is commonly requested for critical engineering materials; 3.2 adds validation by an independent or purchaser-authorized representative depending on the arrangement.

Standards, grades or methods

MTCs typically identify heat/cast number, product, dimensions, standard, grade, chemistry, mechanical tests, heat treatment and inspection results.

Typical applications

Pressure piping, structural projects, oil and gas, power, marine, stainless fabrication and QA/QC dossiers.

Critical checks

Verify certificate authenticity, heat number against physical marking, standard edition, grade, delivery condition, dimensions, test temperatures, required NDT and any third-party endorsement.

Good engineering practice

Use the current governing code or specification and verify manufacturer data, material traceability and project-specific requirements. Where safety, pressure containment or structural integrity is involved, obtain approval from the responsible engineer before changing material, process or acceptance criteria.
