This document specifies the emission limits in relation to electromagnetic disturbances and test conditions for lifts, escalators and moving walks, which are intended to be permanently installed in buildings. These limits however, may not provide full protection against disturbances caused to radio and TV reception when such equipment is used within distances given in Table 1.

This document is not applicable for apparatus which are manufactured before the date of its publication as EN.

This document specifies definitions, requirements and test methods for thermostatic radiator valves referred to hereafter as thermostatic valves.

This standard applies to two port thermostatic valves with or without pre-setting facility and thermostatic integrated valves with or without pre-setting facility for fitting to radiators in wet central heating installations up to a water temperature of 120 °C and a nominal pressure of PN 10.

This standard further specifies the dimensions, the materials and the connection details of four series of straight and angle pattern thermostatic radiator valves of nominal pressure ≤ PN 10.

This standard can be used as reference in a CEN/CENELEC Certification Mark System on thermostatic radiator valves.

This document specifies a communication protocol for networked control systems. The protocol provides peer-to-peer communication for networked control using web-services. The document describes services in layer 2 and layer 3.

The layer 2 (data link layer) specification also describes the MAC sub-layer interface to the physical layer. The physical layer provides a choice of transmission media. The layer 3 (network layer), as described in EN 14908-1, is integrated in UDP/IP communication using IPv4 and IPv6 protocols.

This document specifies the laboratory test methods and test requirements for the testing of aerodynamic, thermal, acoustic and the electrical performance characteristics of non-ducted mechanical supply and exhaust ventilation units used in single dwellings.

The purpose of this document is not to consider the quality of ventilation but to test the performance of the equipment.

In general, a ventilation unit contains:

— fans for mechanical supply and exhaust;

— air filters;

— air-to-air heat exchanger for heat and possibly humidity recovery;

— control system;

— inlet and outlet grilles.

Such equipment can be provided in more than one assembly, the separate assemblies of which are designed to be used together.

Such equipment can contain alternating heat exchangers which provide separate supply and exhaust air flows.

In certain cases, i.e. alternating ventilation unit, the manufacturer may declare that the equipment can be installed in such a way that it serves more than one room. For the purpose of this document, these products are assessed in a single room.

This document does not deal with ducted units or units with heat pumps.

Safety requirements are given in EN 60335-2-40 and EN 60335-2-80.

This document specifies the laboratory test methods and test requirements for the testing of aerodynamic, thermal, acoustic and electrical performance characteristics of ducted mechanical supply and exhaust ventilation units intended for single family houses.

This document is applicable to unit that contain at least, within one or more casing:

— fans for mechanical supply and exhaust;

— air filters;

— air-to-air heat exchanger and/or air-to-air heat pump for air heat recovery;

— control system.

Such unit can be provided in more than one assembly, the separate assemblies of which are designed to be used together.

The different possible arrangements of heat recovery, heat exchangers and/or heat pumps are described in Annex A.

This document does not deal with non-ducted units.

This document does not cover ventilation systems that may also provide water space heating and hot water.

This document does not cover units including combustion engine, driven compression heat pumps and absorption heat pumps.

Electrical safety requirements are given in EN 60335-2-40 and EN 60335-2-80.

This document specifies and classifies the component/product performance characteristics which may be necessary for the design, rating and dimensioning, placing on the market of residential ventilation products and systems to provide the predetermined performance, comfort conditions of temperature, air velocity, humidity, hygiene and sound in the occupied zone.

It defines those performance characteristics (mandatory or optional) which shall be determined, measured and presented according to relevant test methods. It provides a classification scheme which leads to a full definition of product properties based on test methods described in various EN Standards and gives an overview of the test standards. Distinction between mandatory and optional requirement is left to each European and national regulations.

The codification part in Annex A and the classification part in Clause 4 apply to the following products:

— unidirectional mechanical supply and exhaust residential ventilation units according to prEN 13141-4, EN 13141-6 and EN 13141-11;

— ducted mechanical bidirectional residential ventilation units according to prEN 13141-7;

— non-ducted mechanical bidirectional residential ventilation units according to prEN 13141-8.

This European Standard does not apply to other products such as filters, fire dampers, ducts, control devices and sound attenuators, which may also be incorporated in residential ventilation.

This European Standard specifies in Annex ZA and Annex ZB the requirements of EU 1253/2014 and EU 1254/2014 for residential ventilation units below 1 000 m3/h air volume flow.

This European Standard does not cover requirements raised by European Directives (e.g. low voltage directive, EMC directive) and other requirements such as corrosion, fire resistance and snow penetration.

This international standard specifies the evaluation method of life cycle analysis of ductile iron pipes used for water applications.

Studies on economic and environmental impacts are important for utility decision-makers as they seek to balance fiscal concerns over immediate and long-term needs across acquisition, operations and maintenance, and planned end of life. For authorities and engineers designing pipeline systems, the life cycle cost analysis serves as a tool to study various scenarios to determine the right solution for site-specific conditions and community values, as well as provide the necessary data to support those decisions.

Informative Annexes are included in this standard as a compilation of reference and consensual factors (pumping cost, leakage accident rate, etc.) but it is recommended to use local data when they are known and verifiable.
