ASTM A341/A341M-00(2011)e1 使用直流磁导计和冲击试验方法的材料直流磁特性的标准试验方法

Permeameters require the use of yokes to complete the magnetic circuit and are therefore inherently less accurate than ring test methods. Refer to Test Method A596/A596M for further details on ring test methods. However, when testing certain shapes as bars or when magnetic field strength in excess of 200 Oe [15.9 or more kA/m] are required, permeameters are the only practical means of measuring magnetic properties. This test method is suitable for specification acceptance, service evaluation, research and development and design. When the test specimen is fabricated from a larger sample and is in the same condition as the larger sample, it may not exhibit magnetic properties representative of the original sample. In such instances the test results, when viewed in context of past performance history, will be useful for judging the suitability of the material for the intended application. 1.1 This test method provides dc permeameter tests for the basic magnetic properties of materials in the form of bars, rods, wire, or strip specimens which may be cut, machined, or ground from cast, compacted, sintered, forged, extruded, rolled, or other fabricated materials. It includes tests for determination of the normal induction under symmetrically cyclically magnetized (SCM) conditions and the hysteresis loop (B-H loop) taken under conditions of rapidly changing or steep wavefront reversals of the direct current magnetic field strength. 1.2 This test method shall be used in conjunction with Practice A34/A34M. 1.3 This test method covers a range of magnetic field strength in the specimen from about 0.05 Oe [4 A/m] up to above 5000 Oe [400 kA/M] through the use of several permeameters. The separate permeameters cover this test region in several overlapping ranges. 1.4 Normal induction and hysteresis properties may be determined over the flux density range from essentially zero to intrinsic saturation for most materials. 1.5 Recommendations of the useful magnetic field strength range for each of the permeameters are shown in Table 1 . Also, see Sections 3 and 4 for general limitations relative to the use of permeameters. 1.6 The symbols and abbreviated definitions used in this test method appear with Fig. 1 and in appropriate sections of this document. For the official definitions, see Terminology A340. Note that the term flux density used in this document is synonymous with the term magnetic induction. 1.7 WarningMercury has been designated by EPA and many state agencies as a hazardous material that can cause central nervous system, kidney, and liver damage. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury-containing products. See the applicable product Material Safety Data Sheet (MSDS) for details and EPA’s website (http://www.epa.gov/mercury/faq.htm) for additional information. Users should be aware that selling mercury or mercury-containing products, or both, in your state may be prohibited by state law. 1.8 The values and equations stated in customary cgs-emu and inch-pound or SI units are to be regarded separately as standard. Within this standard, 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 may not be exact equivalents; therefore, each system shall be used independently of the other. Combining valu......

Calibration Specification for Sets of Current Ratio Standards at Power Frequency

ASTM F1761-00(2005) 圆形磁射极板磁力线通过量的标准试验方法

It is standard practice to use magnetron cathode sputter deposition sources in manufacturing thin film magnetic data storage media. But a ferromagnetic sputtering target tends to shunt a sputtering cathodersquo; magnetic field, thus reducing the efficiency of the sputtering process. Makers of sputtering targets have developed various means of controlling alloy microstructure to minimize the undesirable cathode shunting effect. Because of their differing manufacturing methods, however, the targets of one supplier may have magnetic properties significantly better or worse than those of another, even when the alloy compositions are the same. This test method permits comparing the magnetic shunting power of magnetic targets under a standard test condition. The results are useful to sputtering target suppliers and buyers in predicting target performance, in specifying target quality, and in qualifying incoming target shipments. This test may also be useful in quantifying target improvement efforts. Manufacturing process steps that lower a target materialrsquo;magnetic permeability tend to increase the PTF, and vice versa. It would in principle be possible to predict the PTF by accumulating sufficient permeability data, and knowing the target thickness and the field intensity of the magnetic assembly used for magnetron sputtering.1.1 This test method covers measuring the dc magnetic field transmitted through a ferromagnetic sputtering target ("pass through flux" or "PTF"). In this test method the source magnetic field is in the test target's circumferential direction.1.2 Planar disk-shaped targets in the diameter range 5 to 8 in. inclusive (125 to 205 mm inclusive) and of thickness 0.1 to 0.5 in. inclusive (2.5 to 13 mm) may be characterized by this procedure.1.3 This test method is also applicable to targets having an open center, for example, to targets 5-in. outside diameter by 2.5-in. inside diameter by 0.25-in. thick (127-mm outside diameter by 63.5-mm inside diameter by 6.35-mm thick).1.4 Targets of various diameters and thicknesses are accommodated by suitable fixturing to align the piece under test with the source magnet mounted in the test fixture.

ASTM E1004-99 导电率的电磁(涡流)测量的标准规程

1.1 This test method describes a procedure for measuring the electrical conductivity of nonmagnetic metals using the electromagnetic (eddy current) method. The procedure has been written primarily for use with commercially available electrical conductivity instruments. General purpose eddy-current instruments may also be used for electrical conductivity measurements but will not be addressed in this test method. 1.2 This test method is applicable to metals that have a flat or slightly curved surface, and metals that may have a thin nonconductive coating. 1.3 Eddy-current measurements of electrical conductivity may be used in the sorting of metals with respect to variables such as: type of alloy, aging, cold deformation, heat treatment, effects associated with nonuniform heating or overheating, and effects of corrosion. The usefulness of tests of these properties is dependent on the amount of electrical conductivity change caused by a change in the specific variable. 1.4 Electrical conductivity, when measured by eddy-current instruments, usually is expressed as a percentage of the conductivity of the International Annealed Copper Standard (IACS). The conductivity of the Annealed Copper Standard (100% IACS) is defined to be 0.58 X 108 S/m at 20176C. 1.5 This standard does not purport to address the safety problems, if any, associated with its use.
