1.1 本试验方法包括使用接触测微计测量柔性包装材料的厚度。 1.2 该测试方法的精度和偏差声明是使用手持式和台式千分尺制定的，其英尺尺寸范围为4.8 毫米至15.9毫米 毫米( 3. / 16 在里面 到 5. / 8. 英寸）。 1.3 以国际单位制或英寸磅单位表示的数值应单独视为标准。每个系统中规定的值可能不是精确的等效值；因此，每个系统应独立于其他系统使用。将两个系统的值组合在一起可能会导致不符合标准。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 4.1 该测试方法提供了一种测量厚度尺寸的方法。厚度的精确测量对于满足规范和表征工艺、产品和材料性能至关重要。 4.2 此测试方法不涉及可接受性标准。这些需要由产品的用户和生产商共同决定。测量的重复性和再现性如“精度和偏差”部分所示。应注意被测材料的固有可变性，因为这可能会影响测量结果。

1.1 This test method covers the measurement of thickness of flexible packaging materials using contact micrometers. 1.2 The Precision and Bias statement for this test method was developed using both handheld and bench top micrometers with foot sizes ranging from 4.8 mm to 15.9 mm ( 3 / 16 in. to 5 / 8 in.). 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. 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 non-conformance with the standard. 1.4 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. 1.5 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 a thickness dimension. Accurate measurement of thickness can be critical to meeting specifications and characterizing process, product, and material performance. 4.2 This test method does not address acceptability criteria. These need to be jointly determined by the user and producer of the product. Repeatability and reproducibility of measurement is shown in the Precision and Bias section. Attention should be given to the inherent variability of materials being measured as this can affect measurement outcome.
