Current edition approved Sept. Work Item s – proposed revisions of this standard. This standard provides an accelerated method to measure the threshold stress or threshold stress intensity for the onset of hydrogen stress cracking in steel within one astmm on only one machine.

Testing shall be continued until crack growth is detected or rupture occurs. Our experts can also help you with statistical analysis and understanding of your testing results.

BoxDenver, Co For routine testing, we offer rapid turnaround using the Rising Step Load system developed by Lou Raymond and his colleagues at Fracture Diagnostics Inc. The RSL system they offer is uniquely capable and suited to performing these tests and can provide data in 24 hours in many cases. Fractographic analysis may be used to verify the existence of subcritical cracking.
