Annotation of standard text ASTM B80-23 :

This specification covers magnesium-alloy sand castings. The castings shall conform to the chemical composition limits specified. The castings may be subjected to such heat treatment as deemed necessary to produce material that will conform to the requirements specified. Heat treatment shall be performed on the whole casting and never on a portion. Foundry control shall consist of examination of the castings by radiographic or other approved methods for determining internal discontinuities until the gating, pouring, and other foundry practices have been established to produce castings meeting the quality standards. The tension test specimens representing the castings shall conform to the requirements.
