标准摘要
[中文适用范围]： 本国际标准规定了从一个或多个烧结零件制备样品以分析游离碳或总碳含量的方法。 结合碳被确定为总碳和游离碳之间的差值。 本标准涵盖了化学方法测定碳的样品制备，即根据 ISO 437 在氧气中燃烧并测量产生的二氧化碳。 它不包括物理方法测定碳的样品制备，例如金相学或光谱学。 [外文原描述]： ISO 7265:2012 specifies methods for preparing a sample from one or more sintered parts to be analysed for free or total carbon content. Combined carbon is determined as the difference between total and free carbon. This standard covers the preparation of samples for the determination of carbon by a chemical method, i.e. combustion in oxygen and measurement of the carbon dioxide produced, in accordance with ISO 437. It does not cover the preparation of samples for carbon determination by physical methods, such as metallography or spectroscopy.
英文名称Sintered metal materials, excluding hardmetals — Preparation of samples for chemical analysis for determination of carbon content
