Scope
This document provides guidance on the test mechanism, test equipment, sample preparation, test methods, result analysis, and test reports for the initial screening test of polypropylene (PP) packaging containers (hereinafter referred to as "containers") contaminated with recycled plastics. This document is applicable to the construction of initial screening test methods for packaging containers made from polypropylene resin as the main raw material and contaminated with recycled plastics. This document is not applicable to the construction of initial screening test methods for products made from other plastics and olefin-based composites contaminated with recycled plastics.
