Anotace textu normy ASTM B94-18 :

This specification covers magnesium-alloy die castings. The magnesium alloys used for the manufacture of die castings shall conform to the chemical composition requirements of this specification. The producer or supplier is responsible for the performance of all inspection and test requirements when specified in the contract or purchase order. Samples for chemical analysis shall be taken from the material by drilling, sawing, milling, turning, or clipping a representative piece or pieces to obtain a weight of prepared sample the soundness of die castings which shall conform to standards or requirements agreed upon between the producer or supplier and the purchaser. Die castings shall have uniform quality that is free from injurious discontinuities that will adversely affect their serviceability. All castings shall be properly marked for identification with the part number, name or brand of the producer, as agreed upon the contract.
