When material test reports (MTR’s) are requested by Xometry, they must state both mechanical and chemical properties of the material, lot or heat number, the specification which the material complies with (AMS, EN, ASME, ASTM, etc.). There also may be instances that the material must be DFARS and NAFTA approved by the USA or qualifying country, not counterfeit and also be mercury-free. These cases will be specified on the Purchase Order. The documentation must be uploaded to the job board and a copy must accompany the shipment.
