本標準規定了一種利用X-Y-Z正交坐標系對相對于產品織構的試樣軸線進行標識的方法,可應用于無缺口(或預裂紋)金屬試樣。
本方法僅適用于可清楚地識別織構規律一致的金屬材料。
在試樣加工之前應確定試樣取向,按照本標準的規定對其標識并做記錄。This International Standard specifies a method for designating test specimen axes in relation to product
texture by means of an X-Y-Z orthogonal coordinate system.
The system applies equally to unnotched and notched (or precracked) test specimens.
The method is intended only for metallic materials with uniform texture that can be unambiguously determined.
Test specimen orientation is decided before specimen machining, identified in accordance with the
designation system specified in this International Standard, and recorded.
