本标准规定了一种利用X-Y-Z正交坐标系对相对于产品织构的试样轴线进行标识的方法,可应用于无缺口(或预裂纹)金属试样。
本方法仅适用于可清楚地识别织构规律一致的金属材料。
在试样加工之前应确定试样取向,按照本标准的规定对其标识并做记录。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.
