ISO/TS 10719:2016规定了在感应炉中燃烧后测定铸铁中非结合碳含量的红外吸收法。 该方法适用于1,0%（质量分数）至3,0%（质量分数）之间的非结合碳含量。 通常存在的元素不会干扰。然而，一些合金铸铁在经过广泛热处理后，含有在使用这种方法时不可溶的碳化物，可能会产生较高的非结合碳值。

ISO/TS 10719:2016 specifies an infrared absorption method after combustion in an induction furnace for the determination of non-combined carbon content in cast irons. The method is applicable to non-combined carbon contents between 1,0 % (mass fraction) and 3,0 % (mass fraction). Elements ordinarily present do not interfere. However, some alloyed cast irons, when extensively heat treated, contain carbides that are not soluble when using this method and may give high values for non-combined carbon.
