This European Standard specifies requirements for design, calculation and installation of factory made thermal insulated bonded single and twin pipe systems for directly buried networks for continuous operation with treated hot water at various temperatures up to 120 ºC and occasionally with peak temperatures up to 140 ºC and maximum internal pressure 2,5 MPA. Flexible pipe systems according to EN 15632 are not under the scope of this standard.The standard EN 13941, Design and installation of thermal insulated bonded single and twin pipe systems for directly buried hot water networks consists of two parts:a) EN 13941-1: Design;b) EN 13941-2: Installation.The requirements and stipulations in this part: prEN 13941-2, form an unbreakable unity with those of prEN 13941-1. This part shall therefore exclusively be used in combination with prEN 13941-1.The principles of the standard may be applied to thermal insulated pipe systems with pressures higher than 2,5 MPa, provided that special attention is paid to the effects of pressure. Adjacent pipes, not buried, but belonging to the network (e. g. pipes in ducts, valve chambers, road crossings above ground etc.) may be designed and installed according to this standard.This standard presupposes the use of treated water, which by softening, demineralisation, de-aeration, adding of chemicals, or otherwise has been treated to effectively prevent internal corrosion and deposits in the pipes.This standard is not applicable for such units as:a) pumps;b) heat exchangers;c) boilers, tanks;d) systems behind domestic substations.

This document specifies the definitions and requirements for unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP), polypropylene with mineral modifier (PP-MD) or polyethylene (PE) storm water road gullies intended for non-pressure use only in storm water and combined systems installed to a maximum depth of 4 m from ground level to the lowest point of the storm water road gully.Storm water road gullies complying with this document are intended to be used in pedestrian or vehicular traffic areas outside the building structure.NOTE 1 Products complying with this document can also be used in non-traffic areas.NOTE 2 Storm water road gullies may be subject to national regulation which limit the maximum installation depth and / or local provisions. The installer should check for compliance prior to installation.Storm water road gullies complying with this document are made from a prescribed set of components that are manufactured from unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP), polypropylene with mineral modifier (PP-MD) or polyethylene (PE) and assembled together.Storm water road gullies complying with this document may be equipped with optional devices (e.g. removable sand or silt bucket, leaf separator etc.), however the performance of these optional devices is not covered within the scope of this document.Storm water road gully components can be manufactured by various methods e.g. extrusion, injection moulding, rotational moulding, low-pressure moulding, blow moulding, thermoforming or fabricated.NOTE 3 Products complying with this standard can be installed in underground applications without additional static calculationNOTE 4 The complete storm water road gully assembly can also include items non-plastic items (near surface or surface components for example) which are not covered by this document.NOTE 5 The complete storm water road gully assembly can be supplied with covers, frame covers and gratings complying with the relevant part of EN 124 [1] which are not covered by this document. However, reference should be made to this document for geometrical characteristics where applicable.NOTE 6 Storm water road gullies can be site assembled from different components, but can also be manufactured as a single unit.- storm water road gullies with or without sand / silt trap;- storm water road gullies with or without water seal preventing odour release;- storm water road gullies where the traffic load will or will not be carried by the complete gully (resp. "Direct loaded storm water gullies" or "Indirect loaded storm water gullies").

This document specifies the definitions and requirements for unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP), polypropylene with mineral modifier (PP-MD) or polyethylene (PE) storm water manholes and storm water inspection chambers intended for non-pressure use only in storm water systems to a maximum depth of 6 m from ground level to the lowest point of the storm water manhole or inspection chamber.NOTE 1 Products complying with EN 13598-2 may also be used for storm water systems dependent on the requirement of the storm water system.Storm water manholes and inspection chambers complying with this document are intended to be used in pedestrian or vehicular traffic areas outside the building structure.NOTE 2 Products complying with this document can also be used in non-traffic areas.Storm water manholes and inspection chambers complying with this document are made from a prescribed set of components that are manufactured from unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP), polypropylene with mineral modifier (PP-MD) or polyethylene (PE) and assembled together.Storm water manholes and inspection chambers complying with this document may be equipped with optional devices (e.g. removable sand or silt bucket, flow regulators, ventilation parts, etc.), however the performance of these optional devices is not covered within the scope of this document.NOTE 3 Products complying with this standard can be installed in underground applications without additional static calculation. NOTE 4 The complete Storm water manhole or inspection chamber assembly can also include items which are not covered by this document (for example near surface or surface components).NOTE 5 Storm water manholes and inspection chambers can be supplied with covers, frame covers and gratings complying with the relevant part of EN 124 [1].Storm water manhole and inspection chamber components can be manufactured by various methods e.g. extrusion, injection moulding, rotational moulding, low-pressure moulding or fabricated.NOTE 6 Storm water manholes and inspection chambers can be site assembled from different components, but can also be manufactured as a single unit.NOTE 7 Storm water manholes and inspection chambers can be subject to national regulations and / or local provisions.

This document specifies a method for determining the longitudinal reversion of thermoplastics pipes, to be carried out in either a liquid or in air. In case of dispute, heated liquid is used as the reference. This International Standard is applicable to all thermoplastics pipes with smooth internal and external walls of constant cross-section. It is not applicable to non-smooth structured-wall thermoplastics pipes. The parameters appropriate to the pipe material and recommendations for the maximum levels of reversion as a function of the pipe material are given in Annex A. This method is applicable for pipes of wall thickness =16 mm.

The existing Annex ZB is still incorrectly referring to the old 97/23/EC Directive. Reference should be made to Directive 2014/68/EU for pressure equipment. To be done via this WI.
