This document provides guidance and information for drafting product standards to specify characteristics and test methods for the utilisation of thermoplastics recyclates (PVC-U, PVC-C, PE, PP, ABS) in pipes, fittings and ancillaries for thermoplastics piping systems.
This document covers recyclates with an agreed specification from all sources.
Note 1: This document does not cover characteristics for reworked material
Note 2: This document does not cover recycling processes (e.g. chemical or mechanical)
Note 3: This document does not define if recycled material can be used in a specific application. The possible use of recyclates will be defined in the applicable product standard.
This document provides guidance about the relevant characteristics to be included in the agreed specification for recyclates.
This document is applicable without prejudice to any existing legislation.
For the recycling process, transport, the testing and the use of thermoplastics recyclates National and/or European regulations (e.g. hygienic aspects) may apply.
Note 4: For example threshold levels for substances of very high concern (SVHC) as defined in the REACH-legislation which can possibly be present in thermoplastic recyclates.
