该文件为德国超声波检验规程
根据欧洲标准化协会/欧洲电工标准化委员会(CEN/ CENELEC)的内部规定,下列国家的国家标准化组织有义务采用本欧洲标准:奥地利、比利时、捷克共和国、丹麦、芬兰、法国、德国、瑞士、冰岛、爱尔兰、意大利、卢森堡、荷兰、挪威、葡萄牙、西班牙、瑞典、瑞士和英国。
1 Scope 第一章 适用范围
This European Standard describes a method for the ultrasonic testing of uncoated flat steel product for internal discontinuities. It is applicable to flat product in nominal thickness range of 6 mm to 200 mm of non-alloyed or alloyed steel, excluding austenitic or austenoferritic steels. However, this standard may be applied to the latter types of steels provided that the difference between the amplitude of the noise signal and that of the echo detection threshold is sufficient for the limit fixed.
本欧洲标准介绍了未经涂布的钢板的内部裂纹现象的超声试验测定方法,适用于厚度在6毫米至200毫米的除奥氏体或奥氏-铁素体以外的合金或非合金钢材产品的检验。但是,如果噪声信号和回声检测阈值之间的差异幅度足以限制固定的话,这一标准可以适用于后者。
This standard also defines four quality classes for the flat product body (classes S0, S1, S2 and S3) and 5 c1asses (E0, E1, E2, E3, E4) for the edges in accordance with the criteria specified in clause 9.
本标准同时为钢板规定了四个质量等级(S0, S1, S2 和 S3级)并根据第九章的质量条款为棱边规定了五个质量等级(E0, E1, E2, E3, E4)。
Other methods of testing (e.g. by transmission) or other test equipments may be used at the manufacturer's discretion provided that they give identical results to those obtained under the conditions of this standard. In the event of a dispute, only the method defined in this standard shall prevail.
