标准范围

ISO 7539-6:2002涵盖了用于调查应力腐蚀敏感性的预裂试样的设计、制备和使用程序。它为研究应力腐蚀敏感性的预裂纹试样的设计、制备和使用提供了建议。ISO 7539本部分中使用的术语“金属”包括合金。由于需要限制裂纹尖端的塑性，预裂纹试样不适用于薄产品（如板材或线材）的评估，通常用于较厚的产品，包括板棒和锻件。它们也可用于通过焊接连接的零件。

ISO 7539-6:2002 covers procedures for designing, preparing and using pre-cracked specimens for investigating susceptibility to stress corrosion. It gives recommendations for the design, preparation and use of pre-cracked specimens for investigating susceptibility to stress corrosion.The term "metal" as used in this part of ISO 7539 includes alloys.Because of the need to confine plasticity at the crack tip, pre-cracked specimens are not suitable for the evaluation of thin products such as sheet or wire and are generally used for thicker products including plate bar and forgings. They can also be used for parts joined by welding.
