This document specifies definitions and recommended specifications and test methods for the utilisation of PVC-U, PP and PE non-virgin materials in components for non-pressure piping systems. This document specifies the use of material with agreed specification in case large quantities are to be used. This document gives information about the relation between relevant characteristics and their influence on processing/performance on pipes and/or fittings. NOTE 1 For the purpose of this specification the term pipes means extruded pipes and any parts of a fabricated fitting which is made from an extruded pipe. The term fitting means injection moulded fittings and injection moulded parts of a fabricated fitting. NOTE 2 The Working Group responsible for the product standard should specify the requirements and permitted deviations of the characteristics specified in the Tables 1, 2 and 3, as well as permitted dosage levels. NOTE 3 The WG responsible for the product standard should seriously consider those recommendations and only permit dosage levels which give a safe compliance with the requirements of the product standard. Further, the WG should seriously 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.
