This document specifies classification, general requirements and test methods for flexible, factory made, buried district heating pipe systems. This document is intended to be used in conjunction with part 2 or 3, as applicable. This document is applicable to a maximum continuous media temperature of 80 °C (part 2 and 3) and design pressures of 0,6 MPa to 1 MPa. The pipe systems are designed for a service life of at least 50 years. For pipe systems with plastic service pipes, the respective temperature profiles are defined in EN XXXX-2 and EN XXXX-3. NOTE For the transport of other liquids, for example potable water, additional requirements can be applicable.
