精密铸造钢件的力学性能检验一般是测屈服点、伸长率及冲击韧性值。每次检查采用一个抗拉试样和两个冲击试样。铜合金铸件一般检查抗拉强度、伸长率和布氏硬度，每次检查采用一个抗拉试样和一个布氏硬度试样。
钢铸件力学性能试验通常用梅花形试样，试样毛坯应在每炉浇注中期单独铸出，并且要随同所代表的铸件一起热处理，其试验内容及要求应根据零件不同的工作条件和技术要求确定，并在工艺文件上注明。按统一标准进行试验。
钢铸件检验时，如果有一个试样不符合规定，则取加倍的试样复试不合格项目。如果其中再有一个试样不合格，则应将所代表的蜡模精密铸造件连同备用的试样再次热处理后试验。如其中又有一个试样不合格时，则试样再加倍复试不合格项目。若其中还有一个试样不合格时，该批试样及代表的铸件应予以报废。
