Doplňujúce informácie
| Significance and Use |
|
3.1 Lamination factor S indicates the deficiency of effective material volume which is due to the presence of oxides, roughness, insulating coatings, and other conditions affecting the strip surface. 3.2 This test method is used to predict the fraction of metal that is included in the volume of the firm coil wound from the specimen tape. |
| 1. Scope |
|
1.1 This test method covers measurements of lamination factor (Note 1) of a specimen composed of strips cut from amorphous magnetic material. It is suitable for the determination of lamination factor for thin, flat case, metallic strip ranging in width from 0.25 to 8.00 in. [6.35 mm to 203 mm] and in thickness from 0.0005 to 0.005 in. [12.7 to 127 μm]. 1.2 The values and equations stated
in customary (egs-emu and inch-pound) or SI units are to be
regarded separately as standard. Within this standard, 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 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. 1.3 The test method also provides procedures for calculating ac peak permeability from measured peak values of total exciting currents at magnetic field strengths up to about 2 Oe [159 A/m]. 1.4 Explanation of symbols and abbreviated definitions appear in the text of this test method. The official symbols and definitions are listed in Terminology A340. 1.5 This test method shall be used in conjunction with Practice A34/A34M. 1.6 The values stated in either 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. 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. 1.7 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. |
