However, it should be noted that this practice may not be appropriate for forms aatm bimetallic construction or service conditions which have not been observed to cause HID in service. Note 1 Open symbolsno disbonding reported. The test temperature and hydrogen gas pressure are selected to simulate those conditions found in refinery hydrogencontaining environments. Open symbols—no disbonding reported.

Review of Hydrogen Induced Disbond Testing

No other units of measurement are included in this standard. We have no amendments or corrections for this standard. The procedures xstm herein, may also be appropriate for evaluation of hot roll bonded, explosive bonded, or other suitable processes for applying stainless alloys on steel substrates.

These procedures can asstm used to assess the effects of material composition, processing methods, fabrication techniques, and heat treatment as well as the effects of hydrogen partial pressure, service temperature, and cooling rate.

See Section 6 for additional safety information. The control system not pictured for the apparatus automatically purges the vessel with argon, performs a high pressure leak test with nitrogen and then sequences the main portion of the test. This system can be used over a broad range of pressures, temperatures, cooling rates, and gaseous hydrogen environments where HID could be a significant problem.

These tests can be used to assess the effects of material composition, processing methods, fabrication techniques, and heat treatment as well as the effects of hydrogen partial pressure, service temperature, and cooling rate.
