适用范围:

5.1 This test method provides a controlled corrosive environment which can be utilized to produce relative corrosion resistance information for sintered permanent magnets.5.2 Although prediction of performance in natural environments has seldom been statistically correlated with corrosion test results, sufficient empirical results are available to support the usefulness of this test in quantifying relative resistance to corrosion from moisture and heat.5.3 The reproducibility of results in this test method is dependent on the type, size, and shape of specimens tested, and the control of the operating variables. In any testing program, sufficient replicates should be included to establish confidence limits. Replicates may be run simultaneously, in subsequent test runs, or in duplicate test chambers.5.4 When multiple test chambers and operators are utilized, efforts shall be made to perform a suitable repeatability and reproducibility study for the equipment, operators, and test method.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 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.
