Attention is drawn to the possibility that some of the elements of this document may be the
15、 subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes CEN/TS 14541:2007. The main changes are: definitions brought in line with common practice; application “Pressure piping systems” is introduced; a genera
16、l guidance has been added for utilisation of non-virgin materials; Annex A “Processing and performance of pipes and characteristics of recyclable material” is deleted. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to anno

PD CEN/TS 14541:2013CEN/TS 14541:2013 (E) 4 1 Scope This Technical Specification specifies definitions and recommended characteristics and test methods for the utilisation of PVC-U, PP and PE non-virgin materials i
19、n 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 tech
20、niques 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. Furt
21、her, 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 pa
22、rts 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 appl
