This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2000, and conflicting national standards shall be withdrawn at the latest by January 2000.本欧洲标准应以国家标准状态发布，或者发行同一的文件或者背书，最迟不得晚于2000年元月份，与本标准相悖的国家标准应在2000年元月份前废止。
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.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.在能够得到与根据本标准条件测得的相一致的结果的前提下，其它试验方法（例如在线测试）或者其它试验设备可以用于制造商对产品内部裂纹现象的判定。
在相左情况下，以本标准为准。
Testing of flat product of thickness less than 6 mm may be the subject of special agreements between the parties concerned.特殊合同的相关方也可以要求对厚度小于6毫米的钢板进行检验。
The inspection is normally carried out in the place of production or on the premises of the supplier. If specified on the order, the inspection may take place in the presence of the purchaser or his representative 1) 。
一般情况下，检验在产品生产地或者在供应商的仓库进行。
如果订单上有相关条款规定，也可以在购买商或其代表的监理下进行注解1）。
A list of equivalent terms in several European languages is given in annex A.附件A给出了相同术语的几种欧洲语言表达形式。
