19、hnical Committee CEN/TC 107 “Prefabricated district heating pipe systems”, the secretariat of which is held by DS. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2009, and conflicting nation
20、al standards shall be withdrawn at the latest by July 2009. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document is one of a

In order to assure quality including product-related lifetime, to assure safety in
25、use, economical energy usage and to facilitate comparability in the market, CEN/TC 107 decided to set up standards for these products.

26、dard provides classification, general requirements and test methods for flexible, pre-insulated, directly buried district heating pipe systems. It is intended to be used in conjunction with parts 2, 3, 4, and 5. Depending on the pipe assembly (see Table 4), this European Standard is valid for maximu
27、m operating temperatures of 95 C to 140 C and operating pressures of 6 bar to 25 bar. The pipe systems are designed for a lifetime of 30 years. For pipe systems with plastic service pipes, the respective temperature profiles are defined in EN 15632-2 and EN 15632-3. NOTE For the transport of other l
28、iquids, for example potable water, additional requirements may be applicable. 2 Normative references The following referenced documents are indispensable for the application of this document.
