本欧洲标准规定了轧制，拉伸，挤压和锻造的坯料，棒材和板材，轧制环和具有均匀正方形，矩形或圆形横截面的锻件的超声波检测程序。它不包括根据相关EN标准或内部规范的技术供应条件进行检查的钢，钛，钛合金，铝合金和耐热合金中的关键旋转部件。 对于具有上述以外几何形状的产品，测试条件和验收标准应由制造商和采购方商定

This European Standard defines the ultrasonic inspection procedure for rolled, drawn, extruded and forged billets, bars and plates, rolled rings and forgings with a uniform square, rectangular or round cross section. It does not cover critical rotating parts in steel, titanium, titanium alloys, aluminium alloys and heat resisting alloys that are to be inspected in accordance with the technical supply conditions of the relevant EN standards or internal specifications. For products with geometries other than those described above, the test conditions and acceptance criteria shall be agreed between the manufacturer and purchaser.
