This Technical Specification specifies definitions and recommended characteristics and test methods for the utilisation of PVC U, PP and PE non-virgin materials in pipes, fittings and ancillaries for both pressure and non-pressure piping systems. This Technical Specification specifies the conditions for utilisation of non-virgin material with and without agreed specification Non-virgin materials may be reformulated by the use of additives and processing techniques to meet an agreed specification. Typically the additives used would be stabilisers and pigments etc. The WG responsible for the product standard should consider the content of this document and only permit dosage levels which give compliance with the requirements of the product standard. Further, the WG should consider whether extra or more frequent product testing is relevant when using such material in the production of pipes and fittings in accordance with the relevant product standard. NOTE For the purpose of this specification the term pipes means extruded pipes, gutters and any parts of a fabricated fitting which is made from an extruded pipe. The term fitting means injection- and rotomoulded fittings and injection moulded parts of a fabricated fitting. For the recycling process, the testing and the use of the non-virgin material National and/or European regulations may apply.
