ASTM International Standard Test Method for Evaluating Hygrothermal Corrosion Resistance of Permanent Magnet Alloys ASTM A1071/A1071M-11

1.1 This 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). 1.2 The 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. 1.3 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.
