1.1 本试验方法建立了薄金属带材畸变测量程序，并将这些测量值应用于表示平面度偏差的等式。 1.2 本试验方法中测量的变形为碟形、波浪形边缘、屈曲、纵向波纹、线圈组和人字纹。 1.3 本试验方法不包括测量纵向卷曲、外倾角或边缘曲率或扭曲。 1.4 本试验方法仅限于金属带0.003 在里面至0.020 在里面(0.08 毫米至0.50毫米），厚度不超过6.0英寸。(150.0 mm）宽。 1.5 单位以英寸-磅单位表示的值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.6 以下安全危险警告仅适用于本试验方法中所述的试验方法: 1.6.1 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。 1.7 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====== 5.1 本试验方法旨在测量用于制造精密公差零件的带材中的变形。因为该带材中的变形会影响正在生产的零件的形状，并导致难以通过闭合件进给- 安装模具和其他制造设备时，这种材料必须平整。 5.2 本试验方法提供了测量导致平面度偏差的不规则性的通用程序。 5.3 该测试方法允许买方和制造商使用标准技术检查带钢，达到双方商定的可接受的平整度百分比偏差，如果是线圈组，则达到可接受的平整度距离偏差。

1.1 This test method establishes a procedure for the measurement of distortions in thin metal strip and the application of these measurements to an equation that will indicate the deviation from flatness. 1.2 The distortions to be measured in this test method are dish, wavy edges, buckle, longitudinal corrugation, coil set, and herringbone. 1.3 This test method is not intended to include the measurement of longitudinal curl, camber, or edgewise curvature, or twist. 1.4 This test method is limited to metal strip 0.003 in. to 0.020 in. (0.08 mm to 0.50 mm) thick and not more than 6.0 in. (150.0 mm) wide. 1.5 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units which are provided for information only and are not considered standard. 1.6 The following safety hazard caveat pertains only to the test method(s) described in this test method: 1.6.1 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. 1.7 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 ====== 5.1 This test method is intended for measuring distortion in strip used for making close tolerance parts. Since distortion in this strip would influence the shape of the part being produced and cause difficulties in feeding through close-fitting dies and other manufacturing equipment, it is important that this material be flat. 5.2 This test method provides a universal procedure for measuring the irregularities that cause the deviation from flatness. 5.3 This test method allows the purchaser and manufacturer to inspect strip with a standard technique to a mutually agreed upon and acceptable percentage deviation from flatness, and in the case of coil set, acceptable distance deviation from flatness.
