• Phạm vi áp dụng / Scope of standard: 1.1 This practice describes sampling procedures and test practices for determination of various magnetic properties of both soft and hard magnetic materials. 1.2 This practice may be used either in conjunction with, or independent of, the standard test methods and materials specifications under the jurisdiction of ASTM Committee A06. In the former situation, the sampling and testing procedures listed herein shall not supersede those found in the individual test methods and materials specifications. In the latter situation, the sampling and testing procedures listed herein shall strictly apply. 1.3 The values stated in either customary (cgs-emu and inch-pound) units or SI units are to be regarded separately as standard. Within this practice, the SI units are shown in brackets except for the sections concerning calculations where there are separate sections for the respective unit systems. the values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with this practice. 1.4 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.
