Scope

This Part of GB/T 39690 specifies methods of preparation of test specimens
and the standard 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.
This Part specifies the requirements for pretreatment conditions and
conditioning of the test specimens.

Summary	This standard specifies standard methods for sample preparation and performance determination of polypropylene (PP) and polyethylene (PE) recycled mixtures of flexible and rigid consumer product packaging for molding and extrusion. It is not suitable for transporting, handling or storing recyclables of dangerous goods. Since it is impossible to obtain information on the content of stabilizers in the recovered materials, it is necessary to add stabilizers as needed. This standard specifies the pretreatment conditions and condition adjustment requirements of the samples.
