scope:

This document specifies the geometries and proposed finishing procedures of the inner surface of hollow test piece of metallic materials filled with a high-pressure gaseous medium. The document specifies a tensile testing procedure to evaluate the effect of high-pressure gaseous medium compared to a high-pressure inert gas or air.

NOTE 1 Temperature range and pressure range depend on the materials to be tested and test gas to be used.

NOTE 2 This document can be used for the screening of metallic materials by evaluating mechanical property changes due to the effects of various test gases, including hydrogen.
