REVISITING THE DISC TEST METHOD FOR THE STUDY OF HYDROGEN EMBRITTLEMENT IN STEEL

The ISO 11114 standard describes the disc test (method A) for selecting materials resistant to hydrogen embrittlement. However, the disc-shaped specimen geometry specified by this standard usually fails in the clamping area, making the test analysis more difficult. This work suggests two new sample geometries to obtain the disc rupture outside the clamping area.
