    Significance and Use

    5.1 This guide is intended to provide recommendations and suggested good practices to determine precise dimensions when necessary for the calculation of properties expressed in physical units. It is not intended to replace practical thickness measurements based on commercial portable tools, nor is it implied that thickness measurements made by the procedures will agree exactly.

    1. Scope

    1.1 This guide covers the determination of the thickness of plastic films where the thickness is used directly in determining the results of tests for various properties. Use this practice except as otherwise required in material specifications or in applicable test standards.

    Note 1Film is defined in Terminology D883 as an optional term for sheeting having a nominal thickness no greater than 0.25 mm (0.010 in).
    Note 2Alternative methods are acceptable if they meet the requirements of measurement precision as noted in this guide.
    Note 3This guide is not intended to address the sampling techniques or the measurement of film thickness for the commercial classification of commercial products or for quality control purposes.

    1.2 The values stated in SI units are to be regarded as the standard.

    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 requirements prior to use.

    Note 4This standard and ISO 4593 address the same subject matter but differ in technical content.
