ISO 18263-2:2015 specifies methods of preparation of test specimens and the standard test methods to be used in determining the properties of mixtures of polypropylene (PP) and polyethylene (PE) recyclate derived from PP and PE used for flexible and rigid consumer packaging for moulding and extrusion. Recyclate from packaging used for the transport, handling, or storage of hazardous goods is not to be used. Since it is impossible to get the information about stabilizer levels of recyclate, it is necessary to add stabilizer as needed. Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing are given in this part of ISO 18263.
