          有誰做過相控陣靈敏度試塊？加工方法如何？缺陷尺寸如何定

不知道您使用相控陣設備是用于何種行業的檢測，檢測何種工件。小弟這邊有的是ASTM E2700-09 Contact Ultrasonic Testing of Welds Using Phased Array中靈敏度試塊的加工方法。
          
標準原文如下：
          
10.3 Reference Reflectors:
          
10.3.1 Straight-Beam Standardization—Correction for straight beam examination may be determined by means of a side drilled hole reflector at 1?4 and 3?4 of the thickness. For thickness less than 50 mm (2 in.), the 1?4-thickness reflector may not be resolved. If this is the case, drill another hole at 1?2 thickness and use the 1?2 and 3?4-thickness reflectors for correction.
          

          
10.3.2 Angle-Beam Standardization—Correction for anglebeam examination may be determined by means of side-drilled hole reflectors at 1?4 and 3?4 of the thickness. The 1?2-thickness depth to a side-drilled hole may be added to the standardization or used alone at thicknesses less than 25 mm (1 in.). For certain combinations of thin wall and small diameter pipe side drilled holes may not be practical and surface notches may be used with agreement between contracting parties.
          

          
10.3.3 The size of the side-drilled hole used for setting sensitivity shall be agreed upon by the contracting parties.Other targets may be substituted for side-drilled holes if agreed upon by the contracting parties。

有前瞻性，比較前衛。國內可能暫時還沒有8
