This European Standard specifies the requirements for solid-wall polyethylene (PE) pipes with smooth internal and external surfaces extruded from the same compound/formulation throughout the wall, fittings and the system for:

— soil and waste discharge applications (low and high temperature) inside buildings (application area code "B");

— soil and waste discharge applications (low and high temperature) for both inside buildings and buried in the ground within the building structure (application area code "BD").

NOTE 1 The intended use is reflected in the marking of products by "B" or "BD.

NOTE 2 For use buried in the ground within the building structure are intended only those components marked with "BD", with a nominal ring stiffness of at least SN4 for dimensions equal to or greater than 75 mm.

This European Standard is also applicable to PE pipes and fittings and the system intended for the following purposes:

— ventilating part of the pipework in association with discharge applications;

— rainwater pipework within the building structure.

It also specifies the test parameters for the test methods referred to in this standard.

This European Standard covers a range of nominal sizes, a range of pipes and fittings series and gives recommendations concerning colours.

NOTE 3 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes, e.g. CEN/TR 13801 [1].

NOTE 4 Pipes, fittings and other components conforming to any of the plastics product standards listed in Annex B can be used with pipes and fittings conforming to this European Standard, provided they conform to the requirements for joint dimensions given in Clause 6 and to the requirements of Table 16.

It applies to pipes and fittings, marked with "B", which are intended to be used inside buildings and outside buildings fixed onto the wall.

It applies to pipes and fittings, marked with "BD", which are intended to be used for both inside buildings and buried in the ground within the building structure.

This standard is applicable to PE pipes and fittings of the following types:

— plain-ended;

— with integral elastomeric ring seal socket;

— for butt fusion joints;

— for electrofusion joints;

— for mechanical joints

where the fittings can be manufactured by injection-moulding or can be fabricated from pipes and/or mouldings.

NOTE 5 EN 476[2] specifies the general requirements for components used in discharge pipes, drains and sewers for gravity systems. Pipes and fittings conforming to this standard fully meet these requirements.

NOTE 6 For information about the chemical resistance of PE, guidance is given in ISO/TR 10358[3] and for rubber materials in ISO 7620[4].

This European Standard specifies methods for testing the sound power level of air/water, brine/water, water/water and direct exchange/water heat pump water heaters and heat pump combination heaters with electrically driven compressors and connected to or including a domestic hot water storage tank for domestic hot water production.

This European Standard comprises only the testing procedure for the domestic hot water production of the heat pump system.

NOTE 1 Testing procedures for simultaneous operation for domestic hot water production and space heating are not treated in this standard. Simultaneous operation means that domestic hot water production and space heating generation occur at the same time and may interact.

NOTE 2 For space heating function, the requirements are given in prEN 12102-1:2015.

This European Standard only applies to water heaters which are supplied in a package of heat pump and storage tank. In the case of water heaters consisting of several parts with refrigerant connections, this European Standard applies only to those designed and supplied as a complete package.

This European Standard does not specify requirements of the quality of the used water.

1.1 This European Standard deals with safety requirements for construction, manufacturing, installation, maintenance and dismantling of electrically operated stairlifts (chair, standing platform and wheelchair platform) affixed to a building structure, moving in an inclined plane and intended for use by persons with impaired mobility:

— travelling over a stair or an accessible inclined surface;

— intended for use by one person;

— whose carriage is directly retained and guided by a guide rail or rails;

— supported or sustained by rope (5.4.4), rack and pinion (5.4.5), chain (5.4.6), friction traction drive (5.4.7), and guided rope and ball (5.4.8).

1.2 The standard identifies hazards as listed in Clause 4 which arise during the various phases in the life of such equipment and describes methods for the elimination or reduction of these hazards when used as intended by the manufacturer.

1.3 This European standard does not specify the additional requirements for:

— operation in severe conditions (e.g. extreme climates, strong magnetic fields);

— operation subject to special rules (e.g. potentially explosive atmospheres);

— handling of materials the nature of which could lead to dangerous situations;

— use of energy systems other than electricity;

— hazards occurring during manufacture;

— earthquakes, flooding, fire;

— evacuation during a fire;

— stairlifts for goods only;

— concrete, hardcore, timber or other foundation or building arrangement;

— design of anchorage bolts to the supporting structure.

NOTE For the actual type of machinery, noise is not considered a significant nor relevant hazard.

1.4 This document is not applicable to power operated stairlifts which are manufactured before the date of publication of this document by CEN.

This European Standard defines the test methods and performance characteristics for rigid or semi-rigid non-metallic ductwork which are used for ventilation and air conditioning of buildings.

This standard does not include flexible ducts such as textile liners, spiral ductwork or others which are handled in EN 13180 or ductwork made from insulation duct board handled in EN 13403. Requirements for the air tightness of the ventilation system for non-residential buildings are given in EN 16798-3. For residential buildings, it is essential to apply national rules.

The standard is developed to test rigid or semi-rigid ventilation ducts and their components under laboratory conditions. It is essential to perform tests on site in accordance with EN 12599.

The test methods and performance characteristics are valid for ventilation ducts with circular, rectangular or other cross sections. This standard covers non-fire rated and fire rated ductwork. It is essential to also test fire rated ventilation ductwork in accordance with EN 1366-1.

This document, in conjunction with ISO 11296-1, specifies requirements and test methods for pipes which are formed on site by spirally winding and jointing a pre-manufactured profiled plastics strip, or a profiled plastics strip and integral locking joiner strip, and used for the renovation of underground non-pressure drainage and sewerage networks.

It applies to spirally-wound pipes of fixed or variable diameter made of profiled plastics strips, with or without steel stiffening elements, and installed by one of two methods.

The first method employs a dedicated winding machine in front of the open end of an existing pipeline, e.g. in a manhole. The pipes thus formed are simultaneously inserted into the existing pipeline by the winding forces, and by certain techniques can also be expanded in diameter after or during insertion.

The second method employs a dedicated winding machine which forms the pipe as it traverses the existing pipeline from one manhole to the next.

It applies to profile plastics strips of unplasticized poly(vinyl chloride) (PVC-U) with integral locking mechanism, or of high density polyethylene (HDPE) with integrally welded joints.
