标准摘要
[中文适用范围]： 这些方法适用于给定材料的锻件（板材、薄板、带材、棒材、棒材、管材、型材、锻件等）和铸件（砂型铸件、冷硬铸件、压铸件、连续铸件、离心铸件）。 该方法旨在确定化学成分是否符合要求。 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，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 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.
