This document is the general part of the series that describes the designation system for plastic recyclates. This document is dealing with recyclates after the recycling operation and prior to converting and compounding (when applicable). It is dealing with preparation of samples and determination of properties. NOTE 1 This document supports the underlaying standards of this series that, per polymer type, provide an overview of the relevant characteristics and typical values for recyclates for use in certain application groups (product families) in combination with the relevant converting technologies. NOTE 2 The overview of the relevant properties is based on and further extends the relevant properties given in EN ISO 10350-1.
