1.1本试验方法包括使用接触测微计测量软包装材料的厚度。 1.2本试验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，脚部尺寸为4.8至15.9 mm( 3. / 16 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值。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。将两个系统的值合并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）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 4.1本试验方法提供了测量厚度尺寸的方法。准确测量厚度对于满足规范以及表征工艺、产品和材料性能至关重要。 4.2本试验方法不涉及可接受性标准。这些需要由产品的用户和生产者共同确定。测量的重复性和再现性如精度和偏差部分所示。应注意被测量材料的固有可变性，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 to 15.9 mm ( 3 / 16 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== 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.
