DIN EN 13142:2013-06

A combination of components or products is required to provide ventilation. These components/products interact to achieve a renewal of the air in a dwelling. There are many possible arrangements of balanced ventilation units with heat exchanger intended for a single family dwelling (apartment or house) (EN 13141-7) or a single room (EN 13141-8). Additionally all kinds of units might have a heat exchanger, a heat pump or both. It is important to consider each product not only individually but also as part of the whole system: for example from the outdoor canopy of an externally mounted air transfer device to the roof outlet terminal at the end of an exhaust duct. To enable good design it is essential that certain performance characteristics for each product are available in a simple and comparable form. This new edition of DIN EN 13142 specifies and classifies the component/product performance characteristics which may be necessary for the design and dimensioning of residential ventilation systems to provide the predetermined comfort conditions of temperature, air velocity, humidity, hygiene and sound in the occupied zone. The standard 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 national regulations. The codification part in Annex A and the classification part in clause 4 apply to mechanical supply and exhaust ventilation units for single dwellings (apartment or house) according to EN 13141-7 and un-ducted mechanical supply and exhaust ventilation units for a single room according to EN 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 does not cover requirements raised by European Directives, for example: low voltage directive, EMC directive and other requirements such as corrosion, resistance and snow penetration. The following modifications have been made with respect to the previous version of DIN EN 13142:2004-04: - references to DIN EN 13141-1 to DIN EN 13141-10 have been updated; - reference to humidity controlled air transfer devices (DIN EN 13141-9 and DIN EN 13141-10) has been added; - un-ducted mechanical supply and exhaust ventilation units (including heat recovery) for mechanical ventilation systems intended for a single room (EN 13141-8) added in 4.10; - creation of new classification and codification system for mechanical supply and exhaust ventilation units (EN 13141-7 and EN 1341-8), described in 4.9 and 4.10 and in Annex A; - declaration of filters and materials used in the units has been added in 7.3 and - an example for a possible national annex has been added in Annex C. The standard EN 13142:2013 has been prepared within Technical Committee CEN/TC 156 "Ventilation of Buildings" (secretariat: BSI, Great Britain) at the European Committee for Standardisation (CEN). The responsible national Working Committee NA 041-02-51 AA "Lüftung von Wohnungen (SpA CEN/TC 156/WG 2 und CEN/TC 156/WG 16") ("Residential ventilation (Mirror committee CEN/TC 156/WG 2 and CEN/TC 156/WG 16)") of the Heating and Ventilation Technology Standards Committee (NHRS) at DIN, the German Institute for Standardization e. V. participated in the preparation of this standard.
