GB/T 11259-2015 in English

《GB/T 11259-2015无损检测 超声检测用钢参考试块的制作和控制方法》由TC56（全国无损检测标准化技术委员会）归口，主管部门为国家标准化管理委员会。
本标准规定了超声检测用钢参考试块的制作和控制程序,试块提供平面声波入射、形状为圆柱体,内含有平底孔(FBH),可用于超声检测仪器和探头的性能,以及合金产品超声检测的校准和控制。所述参考试块既适用于直接接触法也适用于液浸脉冲回波法。
虽然本标准基本上是论述碳钢及合金钢试块的制作和检验,以及这些材料的检测,但是其制作和检验方法也适用于其他材料,如镍基合金、某些铝合金等的试块制备。当制作除碳钢及合金钢以外的材料的参考试块时,也许需要一些附加的规程和检验。在特定应用场合,本标准不排除一些规范以及认为必要的一些附加补充要求。
其他形状的钢参考试块的制作和控制,可参照本标准使用。，以及这些材料的检测，但是其制作和检验方法也适用于其他材料，如镍基合金、某些铝合金等的试块制备。当制作除碳钢及合金钢以外的材料的参考试块时，也许需要一些附加的规程和检验。在特定应用场合，本标准不排除一些规范以及认为必要的一些附加补充要求。

Scope

This standard specifies the production and control procedures of steel reference test blocks for ultrasonic testing. The test blocks provide plane acoustic wave incidence, are cylindrical in shape, and contain flat-bottomed holes (FBH), and can be used for the performance of ultrasonic testing instruments and probes, as well as alloy products. Calibration and control of ultrasonic testing. The reference block is suitable for both the direct contact method and the liquid immersion pulse echo method. Although this standard basically discusses the manufacture and inspection of carbon steel and alloy steel test blocks, as well as the testing of these materials, its manufacturing and inspection methods are also applicable to test blocks of other materials, such as nickel-based alloys, certain aluminum alloys, etc. preparation. When making reference blocks of materials other than carbon and alloy steels, some additional procedures and inspections may be required. In specific applications, this standard does not exclude some specifications and some additional supplementary requirements that are considered necessary. The production and control of steel reference test blocks of other shapes can be used with reference to this standard.
