This document specifies requirements and test methods for flexible, factory made, buried district heating pipe systems with plastic service pipes and no bonding between the layers of the pipe assemblies.
It is only applicable in conjunction with part 1.
This document is applicable to pipes, fittings, their joints and to joints with components made of non-plastics materials intended to be used for district heating installations.
This document is applicable to a maximum operating temperature of 95 °C and maximum operating design pressure up to 1,0 MPa for a design service life of at least 30 years.
This document does not apply to cover surveillance systems.
NOTE   For higher temperatures or for the transport of other fluids, for example potable water, additional requirements and testing is needed. Such requirements are not specified in this document.

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, 3 or 4, as applicable.
Depending on the pipe assembly (see Table 4), this document is applicable to a maximum operating temperature of 95 °C (part 2 and 3) and a maximum operating temperature of 120 °C (for part 4) and design pressures of 0,6 MPa to 2,5 MPa.
The pipe systems are designed for a service life of at least 30 years. For pipe systems with plastic service pipes, the respective temperature profiles are specified in EN 15632-2 and EN 15632-3.
NOTE   For the transport of other liquids, for example potable water, additional requirements can be applicable.
