标准摘要
[中文适用范围]： 这些方法适用于铸造未锻轧产品（精炼型材）形式的给定材料，例如饼、钢坯、线材和钢锭。 这些方法旨在确定是否符合化学成分的要求。 ISO 1811 的第一部分与 ISO 1811-2 和 1811-3 一起取消并取代了 ISO 建议 R 1811:1971，构成了该建议的技术修订版。 [外文原描述]： The methods are applicable to the given materials in the form of cast unwrought products (refinery shapes) such as cakes, billets, wire bars and ingots. The methods are intended to determine compliance with the requirements for chemical composition. Together with ISO 1811-2 and 1811-3 this first part of ISO 1811 cancels and replaces ISO Recommendation R 1811:1971, of which it constitutes a technical revision.
