Significance and Use
Defects in film are not acceptable to the end-user as there is a reduction in the fitness-for-use in many applications. This document is intended to be a guide to assist users in the inspection and observation of defects.
This guide is applicable in a laboratory environment as a quality control or as a research tool. It is also appropriate for use in any commercial process used to produce film including calendering and solvent casting.
This guide is also suitable for use as an evaluation or screening tool for materials intended to be used in other processes where defects of this nature are also critical, such as fiber spinning and non-wovens.
The individual user must establish the relationship between the criteria and acceptance for fitness-for-use and the observed defects, as it varies by polymer and application. This is attained by the collection of data over a time-period to establish acceptable control limits.
1.1 This guide is intended to provide suggested approaches and criteria for the observation and reporting of defects in various types of plastic film, by means of an optical scanning system.
1.2 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.
Note 1—There is no known ISO equivalent to this standard.
