ISO 4492:2013规定了在类似条件下处理时，与金属粉末的压实和烧结相关的尺寸变化与参考粉末相比较的方法。 该方法适用于金属粉末处理涉及的三种尺寸变化的测定，不包括用于硬质合金的粉末

ISO 4492:2013 specifies a method by which the dimensional changes associated with compacting and sintering of metallic powders are compared with those of a reference powder when processed under similar conditions. The method applies to the determination of three types of dimensional changes involved with the processing of metallic powders, excluding powders for hardmetals.
