1.1 本试验方法包括软包装和包装材料的线性尺寸测量。建议使用允许公差范围为3 毫米( 1. / 8. 英寸）或更高，基于“精度和偏差”一节中所述的量具重复性和再现性。 1.2 以国际单位或英寸-磅单位表示的数值应单独视为标准值。每个系统中所述的值不一定精确相等；因此，为了确保符合标准，每个系统应独立于另一个系统使用，并且两个系统的值不应合并。 1.3 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====== 4.1 本试验方法提供了测量线性尺寸的方法。尺寸的准确测量对于满足规范和表征工艺性能至关重要。 4.2 本试验方法不适用于小于3 mm的公差范围( 1. / 8. 英寸）测试误差最好不超过30 % 公差范围。 有关量规重复性和再现性结果，请参见精度和偏差部分。 4.3 本试验方法不涉及验收标准。这些需要由产品的用户和生产商共同确定。

1.1 This test method covers the measurement of linear dimension of flexible packages and packaging materials. It is recommended for use with an allowable tolerance range of 3 mm ( 1 / 8 in.) or greater based on gauge repeatability and reproducibility presented in the Precision and Bias section. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.3 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 ====== 4.1 This test method provides a means for measuring linear dimensions. Accurate measurement of dimensions can be critical to meeting specifications and characterizing process performance. 4.2 This test method should not be applied to tolerance ranges of less than 3 mm ( 1 / 8 in.) when it is preferable that test error does not exceed 30 % of tolerance range. See Precision and Bias Section for gauge repeatability and reproducibility results. 4.3 This test method does not address acceptability criteria. These need to be jointly determined by the user and producer of the product.
