1.1 This practice describes the techniques used for detecting two different polymer entities such as:
1.1.1 Abnormal specks or spots on a surface or in the film that are objectionable as defects and
1.1.2 Layers of different polymeric sheets commonly used as barrier films made by coextrusion.
1.2 This practice utilizes through-transmittance optical and infrared techniques.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 7. NOTE 1—There is no known ISO equivalent to this standard.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
