1.1 本试验方法包括层压系数的测量( 注1 )由从非晶磁性材料上切下的条状物组成的试样。它适用于测定宽度在0.25至8.00英寸之间的薄扁平金属带的层压系数。[6.35 mm至203 mm]，厚度为0.0005至0.005 in。[12.7至127μm]。 注1: 叠层因子也称为空间因子或叠加因子。 1.2 以惯用（egs emu和英寸磅）或国际单位制表示的值和方程应单独视为标准。在本标准中，国际单位制显示在括号中。每个系统中规定的值可能不是精确的等效值；因此，每个系统应相互独立使用。合并两个系统的值可能会导致不符合本标准。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 3.1 层压系数 S 表示由于氧化物、粗糙度、绝缘涂层和其他影响带钢表面的条件的存在而导致的有效材料体积不足。 3.2 该测试方法用于预测从样品带缠绕的牢固线圈体积中包含的金属分数。

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 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 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. ====== 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.
