这些方法适用于锻造产品（板材、薄板、带材、棒材、棒材、管材、型材、锻件等）和铸件（砂型铸件、冷铁铸件、压铸件、连续铸件、离心铸件）形式的给定材料。这些方法旨在确定是否符合化学成分的要求。ISO 1811的这一部分与ISO 1811-1和1811-3一起取消并取代了ISO建议R 1811:1971，它构成了ISO建议R 1811:1971的技术修订版。

The methods are applicable to the given materials in the form of wrought products (plate, sheet, strip, rod, bar, tube, profile, forgings, etc.) and castings (sand castings, chill castings, die castings, continuous castings, centrifugal castings).The methods are intended to determine compliance with the requirements for chemical composition. Together with ISO 1811-1 and 1811-3 this part of ISO 1811 cancels and replaces ISO Recommendation R 1811:1971, of which it constitutes a technical revision.
