This document gives requirements and guidance for the assessment of conformity of compounds/formulations, products, joints and assemblies in accordance with the applicable parts of EN 17176 intended to be included in the manufacturer’s quality plan as part of the quality management system and for the establishment of certification procedures.NOTE 1 It is recommended that the quality management system conforms to or is no less stringent than the relevant requirements to EN ISO 9001 [1].NOTE 2 If certification is involved, it is recommended that the certification body is accredited to EN ISO/IEC 17065 [2] or ENISO/IEC 17021 [3], as applicable.NOTE 3 In order to help the reader, a basic test matrix is given in Annex A.In conjunction with EN 17176-1, EN 17176-2, CEN/TS 17176-3 and EN 17176-5, this document is applicable to oriented unplasticized poly(vinyl chloride) (PVC-O) plastics piping systems for water supply and for buried and above-ground drainage, sewerage and irrigation under pressure.

This document specifies requirements and test methods for factory made thermally insulated flexible pipe-in-pipe assemblies for directly buried district cooling distribution systems, comprising a service pipe and a casing of polyethylene. The pipe assembly can also include the following additional elements: measuring wires, spacers and diffusion barriers.This document is intended to be used in conjunction with FprEN 17414 2 or FprEN 17414 3.This document applies only to insulated pipe assemblies, for continuous operation with water at various temperatures (1 to 30) °C and a maximum operation pressure of 25 bar dependent on material specified.The design is based on an expected service life with continuous operation of a minimum 50 years. For pipe systems with plastic service pipes, the respective temperature profiles are defined in FprEN 17414 2 and FprEN 17414 3.NOTE For the transport of other liquids, for example potable water, additional requirements could be applicable.

This document specifies requirements and test methods for factory made thermally insulated bonded flexible pipe-in-pipe assemblies for directly buried district cooling distribution systems, comprising a service pipe and a casing of polyethylene. The pipe assembly can also include the following additional elements: measuring wires, spacers and diffusion barriers.This document is intended to be used in conjunction with FprEN 17414 1.This document applies only to insulated pipe assemblies, for continuous operation with water at various temperatures (1 to 30) °C and a maximum operation pressure of 25 bar dependent on material specified.The design is based on an expected service life with continuous operation of a minimum 50 years.This document does not cover surveillance systems.In conjunction with the other parts of FprEN 17414, 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 cooling installations.NOTE For the transport of other liquids, for example potable water, additional requirements could be applicable.

This document specifies requirements and test methods for factory made thermally insulated non bonded flexible pipe-in-pipe assemblies for directly buried district cooling distribution systems, comprising a service pipe from DN 15 to DN 200 and a casing of polyethylene. The pipe assembly may also include the following additional elements: measuring wires, spacers and diffusion barriers.This document is intended to be used in conjunction with prEN 17414-1 ).This document applies only to insulated pipe assemblies, for continuous operation with water at various temperatures (1 to 30) °C and a maximum operation pressure of 25 bar dependent on material specified.The design is based on an expected service life with continuous operation of a minimum 50 years.This document does not cover surveillance systems.NOTE For the transport of other liquids, for example potable water, additional requirements may be applicable.
