ASTM A900/A900M-01

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].

Note 1—Lamination factor is also termed space factor or stacking factor.

1.2 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 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.
