ISO 7627的后续部分规定了测定多种元素含量的方法(见表)。该方法适用于铬、铌、钽、钛、钨、钒、这些碳化物和粘结金属的混合物、由这些金属制成的所有等级的预烧结或烧结硬金属以及在完全去除涂层后的涂层硬金属,其元素如表所示。
Subsequent parts of ISO 7627 specify methods for determination of the content of a number of elements (see the table). The method is applicable to cabides of chromium, niobium, tantalum, titanium, tungsten, vanadium, mixtures of these carbides and binder metals, all grades of presintered or sintered hardmetals, produced from these cabides, and coated hardmetals, after total removal of coating, with the elements shown in the table.
