1.1 This test method covers the procedure for measuring diffusible hydrogen in steels by an electrochemical method.
1.2 This test method is limited to carbon or alloy steels, excluding austenitic stainless steels.
1.3 This test method is limited to flat specimens to which the cell can be attached (see 4.6 and 4.8).
1.4 This test method describes testing on bare or plated steel after the plate has been removed (see 4.4).
1.5 This test method is limited to measurements at room temperature, 20 to 25°C (68 to 77°F).
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
