精密铸造配件里的锰含量的测量一直没有一个统一标准，各种各样方式各有不同，为了能行业标准的实施，这儿汇总储存，留之备用。
要测量精密铸件里的Mn，都可以找到有关的标准，例如：锰含量的检测GB/T5121.14-2008，都可以找到我需要的详尽回答，而且有很详尽的流程。
至于说什么牌子的721测量规范确，那你先参考一下哪一个标准，看一下具体的测量是在哪些光波长测量的，若是在360-1000以内，选择721能够解决困难，不然就需要紫外可见光度计。费用预算较为充沛得话，能够选择日本的；假如费用预算偏少得话，能够选择国产。
简单来说，不锈钢精密铸造配件中标钢的Mn含量是已知的、已知，将标钢加工后，你配出一系列浓度c不等的水溶液，随后测吸光度值A，做出一条标曲；再换你配制的试品水溶液测吸光度值，依据曲线图得到Mn的浓度值，就可以测算样品Mn含量。
