本文件规定了试样的尺寸和对圆柱形试样进行纵向拉伸试验的试验程序，以确定熔焊接头中焊接金属的机械性能。 本文件适用于所有形式产品的金属材料，其接头由任何熔焊工艺制成，接头尺寸足以获得符合ISO 6892-1尺寸的圆柱形试样。 除非本文件中对特定点另有规定，否则ISO 6892-1的一般原则适用。

This document specifies the sizes of test specimens and the test procedure for carrying out longitudinal tensile tests on cylindrical test specimens in order to determine the mechanical properties of weld metal in a fusion welded joint. This document applies to metallic materials in all forms of product with joints made by any fusion welding process, having joint sizes that are sufficient to obtain cylindrical test specimens with dimensions in accordance with ISO 6892？1. Unless specified otherwise for specific points in this document, the general principles of ISO 6892？1 apply.
