ASTM A598/A598M-02(2022) 磁放大器芯磁性的标准试验方法

1.1 This test method covers the determination of the magnetic performance of fully processed cores for magnetic amplifier-type applications. 1.2 Tests may be conducted at excitation frequencies of 60 Hz, 400 Hz, 1600 Hz, or higher frequencies. 1.3 Permissible core sizes for this test method are limited only by the available power supplies and the range and sensitivity of the instrumentation. 1.4 At specified values of full-wave sinusoidal-current excitation, Hmax, this test method provides procedures of determining the corresponding value of maximum induction, Bmax. 1.5 At specified values of half-wave sinusoidal-current excitation, this test method provides procedures for determining the residual induction, Br. 1.6 At increased specified values of half-wave sinusoidalcurrent excitation, this test method provides procedures for determining the dc reverse biasing magnetic field strength, H1, required to reset the induction in the core material past Br to a value where the total induction change, ∆B1, becomes approximately one third of the induction change, 2 Bp. It also provides procedures for determining the additional dc reset magnetic field strength, ∆H, which, combined with H1, is the value required to reset the induction in the core material past Br to a value where the total induction change, ∆B2, becomes approximately two thirds of the induction change 2 Bp. 1.7 This test method specifies procedures for determining core gain from the corresponding biasing and induction changes, ∆H and ∆B. 1.8 This test method covers test procedures and requirements for evaluation of finished cores which are to be used in magnetic-amplifier-type applications. It is not a test for basicmaterial magnetic properties. 1.9 This test method shall be used in conjunction with Practice A34/A34M. 1.10 Explanations of symbols and abbreviated definitions appear in the text of this test method. The official symbols and definitions are listed in Terminology A340. 1.11 The values and equations stated in customary (cgs-emu and inch-pound) or SI units are to be regarded separately as standard. Within this test method, SI 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 test method. 1.12 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. 1.13 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.

ASTM A1070-16(2022) 铸造和烧结铝镍钴永磁体的标准规范

1.1 This specification covers technically important, commercially available, magnetically hard, cast and sintered permanent magnets known commonly as Alnico. 1.2 Alnico magnets have approximate magnetic properties of residual magnetic induction, Br, from 0.52 T (5200 G) to 1.35 T (13500 G) and coercivity, HcB, from 38 kA/m (475 Oe) to 175 kA/m (2200 Oe). Their specific magnetic hysteresis behavior (demagnetization curves) can be characterized using Test Method A977/A977M. 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to customary (cgs-emu and inch-pound) units which are provided for information only and are not considered standard. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 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.
