This European Standard describes a method for the ultrasonic testing of uncoated flat steel product f
or 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.

For the purpos of this European Standard, the definitions given in pr EN 1330-4 and the following definitions apply:
为了确切地理解本标准,本欧洲标准采用下列术语定义和pr EN 1330-4定义的术语:
3.1 internal discontinuity 内部裂纹
any imperfection lying within the thickness of the flat product, e.g. planar or laminar imperfection, single-plane or multi-plane inclusion bands or clusters
任何存在于钢板产品厚度内的缺陷,例如平面或薄片状的缺陷,单层的或多层的,无论带状还是丛生状。NOTE It is referred in the text as discontinuity. 说明标准中称为裂纹。
3.2 defect 缺陷
unacceptable internal discontinuity, i.e. exceeding the specified maximum size or population density limits
不可接受的内部裂纹,也就是裂纹尺寸超出了规定的最大限度或密度分布超出了极限数量。
3.3 Population density 分布密度
the number of individual internal discontinuities of a size greater than a specified minimum size and less than a specified maximum size per specified area of body or length of edge zone
在规定的区域或一定的棱边长度范围内,那些大于最小尺寸、小于最大尺寸的单一裂纹的数量。
3.4 manual and assisted manual testing 手动检测和辅助手动检测

of the echo of a flat-bottomed hole of a given diameter and located at the same depth as the discontinuity.
通过比较来自平底孔和被测试区域的回声振幅来锁定裂纹缺陷的存在与否及其大小和深度。
