標題: ASME V 鍛件校準試塊制作 不清楚

各位老師，
          
請教如下：ASME 第V卷第5章對鍛件材料檢測，校準試塊規定不詳。文章僅規定了管狀產品、鑄件、螺栓。
          
                假如需對軸檢驗，如何制作鍛件校準試塊？

鍛件按照SA-388/SA-388M或SA-745/SA-745M進行檢驗。
          
T-571.2 Forgings and Bars.
          
(a) Forgings and bars shall be examined in accordance with SA-388/SA-388M or SA-745/SA-745M, as applicable, except as amended by the requirements elsewhere in this Article.
          
(b) All forgings and bars shall be examined by the straight-beam examination technique.
          
(c) In addition to (b), ring forgings and other hollow forgings shall also be examined by the angle-beam examination technique in two circumferential directions, unless wall thickness or geometric configuration makes anglebeam examination impractical.
          
(d) In addition to (b) and (c), ring forgings made to fine grain melting practices and used for vessel shell sections shall be also examined by the angle-beam examination technique in two axial directions.
          
(e) Immersion techniques may be used.

A388規定貌似也不詳細：只是說了一下孔大小，沒有具體圖紙。

試塊的制作參照ASTM E428標準。
