National foreword

This British Standard is the English language version of EN ISO 3651-2:1998.

It is identical with ISO 3651-2:1998. It supersedes BS 5903:1980 which is

withdrawn.

The UK participation in its preparation was entrusted to Technical Committee

ISE/72, Methods of physical and metallographic testing, which has the

responsibility to:

— aid enquirers to understand the text;

— present to the responsible international/European committee any

enquiries on the interpretation, or proposals for change, and keep the UK

interests informed;

— monitor related international and European developments and

promulgate them in the UK.

A list of organizations represented on this committee can be obtained on

request to its secretary.

Cross-references

Attention is drawn to the fact that CEN and CENELEC Standards normally

include an annex which lists normative references to international

publications with their corresponding European publications. The British

Standards which implement these international or European publications may

be found in the BSI Standards Catalogue under the section entitled

“International Standards Correspondence Index”, or by using the “Find”

facility of the BSI Standards Electronic Catalogue.

A British Standard does not purport to include all the necessary provisions of

a contract. Users of British Standards are responsible for their correct

application.

Compliance with a British Standard does not of itself confer immunity

from legal obligations.

摘要：

BS EN ISO 3651-2-1998 是一项由英国标准化协会（BSI）采纳的欧洲标准，等同于国际标准 ISO 3651-2，专门用于不锈钢晶间腐蚀的测定方法。该标准详细规定了不锈钢在特定腐蚀介质中的试验程序，特别是针对铁素体、奥氏体及铁素体-奥氏体双相不锈钢的腐蚀敏感性评估。其核心内容包括：在硫酸铁(III)溶液（硫酸-硫酸铁法）中进行晶间腐蚀试验，通过评估试样在沸腾介质中暴露后的弯曲性能或金相微观组织变化，来判定材料是否具有晶间腐蚀倾向。该标准广泛应用于化工、石油、造船及核工业等领域，用
