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.
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.
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 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.
