It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The test temperature and hydrogen gas pressure are astk to simulate those conditions found qstm refinery hydrogen-containing environments.

However, due to the broad range of possible materials, test conditions, and variations in test procedures, it is up to the user of this practice to determine the suitability and applicability of these procedures for evaluation of such materials. The test cell is then automatically vented, purged and cooled further so that the test samples can be safely retrieved.

Two gas booster pumps, one for nitrogen and the other for hydrogen, are used for pressurizing the test cell. The main test consists of filling the test cell with hydrogen, heating the vessel at a user defined temperature set point for a period of typically 48 hours. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Are you sure you want to empty the cart? The HID produced by these procedures may not correlate directly with service experience for particular applications. Typically, longer exposure times at the test conditions must be utilized to allow for the resistance to decarburization, internal blistering or cracking, or both, to be evaluated.

Disbonding Test

The procedures described herein, may also be appropriate for evaluation of hot roll bonded, explosive bonded, or other suitable processes for applying stainless alloys on steel substrates. This practice is applicable over a broad range of pressures, temperatures, cooling rates, and gaseous hydrogen environments where HID could be a significant problem. E3 Guide for Preparation of Metallographic Specimens. Copyright Compu-tecture, Inc. Significance and Use 5.

The HID produced by these procedures may not correlate directly with service experience for particular applications. The control system 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 practice is applicable over a broad range of pressures, temperatures, cooling rates, and gaseous hydrogen environments where HID could be a significant problem.

Additionally, this practice does not address the evaluation of high-temperature hydrogen attack in the steel substrate. However, due to the broad range of possible materials, test conditions, and variations in test procedures, it is up to the user of this practice to determine the suitability and applicability of these procedures for evaluation of such materials.
