This document provides requirements and test methods for flexible, factory made, buried district heating pipe systems with metallic service pipes and bonding between the layers of the pipe assemblies and thermal insulation materials of polyurethane or polyisocyanurate foam, the casing being made of polyethylene.It shall be used in conjunction with part 1.This document is valid for maximum media temperatures up to 120 °C and, occasionally peak temperatures up to 140 °C for maximum 300 h/a, and a design pressure up to 2,5 MPa for a design lifetime of at least 30 years.This document covers surveillance systems.In conjunction with the other parts of EN 15632, 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.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 European Standard provides requirements and test methods for flexible, pre-insulated, directly buriedheating pipes with plastics service pipes and bonding between the layers of the pipes.This European Standard is valid for maximum operating temperatures of 95 °C and maximum operatingpressures up to 10 bar for a design lifetime of at least 30 years.This European Standard does not cover surveillance systems.NOTE For higher temperatures or for the transport of other fluids, for example potable water, additional requirementsand testing is needed. Such requirements are not specified in this European Standard.

This document provides 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 valid for maximum media temperature of 95 °C (part 2 and 3) and maximum media 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 defined in EN 15632-2 and EN 15632-3.NOTE For the transport of other liquids, for example potable water, additional requirements may be applicable.

This document provides requirements and test methods for flexible, factory made, buried district heating pipes systems with plastic service pipes and no bonding between the layers of the pipe assemblies.It shall be used in conjunction with part 1.This document is valid for maximum operating temperature of 95 °C and maximum operating design pressure up to 1,0 MPa for a design lifetime of at least 30 years.This document does not cover surveillance systems.In conjunction with the other parts of EN 15632, 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.NOTE For higher temperatures or for the transport of other fluids, for example potable water, additional requirements and testing is needed.

This International Standard, in conjunction with ISO 11298-1, specifies requirements and test methods for cured-in-place pipes and fittings used for the renovation of underground water supply networks. It applies to the use of various thermosetting resin systems, in combination with compatible fibrous carrier materials and other process-related plastics components.

ISO 4918:2016 specifies methods for determining the change of appearance and stability of a textile floor covering or any damage caused by detachment of layers, opening of joints, or crazing of a resilient or laminate floor covering under the movement of a castor chair.

This document gives the recommended practise for underground open trench installation and commissioning of thermoplastics piping systems to be used for the conveyance of water under pressure (in addition to EN 805) and for the discharge of wastewater under gravity (in addition to EN 1610) . In the field of non-pressure underground drainage and sewerage this is reflected in the marking of products by application code "U" and "UD":- outside the building structure (U);- both buried in ground within the building structure (application area code "D") and outside the building (application area code "UD").This document covers also installation and/or connections to valves, manholes, inspection chambers, gullies and other ancillary components in piping systems.NOTE 1 Code of practise for pipelines for gas supply is covered by EN 12007-series [21].NOTE 2 Recommended practices for installation of plastic piping systems for soil and waste discharge within the building structure is covered by CEN/TR 13801 [12].NOTE 3 Practices for underground installation of rainwater infiltration and storage attenuation systems are covered by CEN/TR 17179 [13].NOTE 4 It is assumed that additional recommendations and/or requirements are detailed in the individual product standards.NOTE 5 If non-plastic components are part of the plastic system the manufacturer's instructions should be taken into account.Requirements and instructions concerning commissioning of systems can be found in EN 805 and EN 1610 and the relevant national and/or local regulations. This document gives specific additional recommendations for commissioning relevant for plastic piping systems.Attention is drawn to any relevant local and/or national regulations (e.g. health, safety and hygienic requirements).
