Standard Test Method for Determining Plastic Film Thickness and Thickness Variability Using a Non-Contact Capacitance Thickness Gauge

Importancia y uso:

5.1 This test method provides precise dimensions necessary for the calculation of properties expressed in physical units.

5.2 This test method provides a means to characterize the variability of the material thickness in the transverse and machine directions for quality control purposes, production process support and analysis, incoming product inspection and for defining variability for buying/selling film.

5.3 This test method provides a method for instrument calibration utilizing traceable standards available from the National Institute of Standards and Technology (NIST).

5.4 It is not intended to replace other thickness measurements based on commercial portable tools, nor is it implied that thickness measurements made by different procedures will exactly agree.
