ASTM A1071/A1071M-11(2023)

1.1This test method covers the equipment, procedures, and measurement of the resistance of permanent magnet alloys against corrosion in high temperature, high pressure water vapor environments. This test is also known as the Bulk Corrosion Test (BCT).

1.2The values and equations stated in customary (cgs-emu and inch-pound) units or SI units are to be regarded separately as standard. Within this standard the SI units, when different from customary units, are shown in brackets, the values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with this standard.

1.3This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4This 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.
