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 aerodynamic, acoustic and electrical power performance test methods for unidirectional ventilation units used in residential ventilation systems.

This document is applicable to ventilation units:

—    installed on a wall or in a window without any duct, A category;

—    installed in the upstream of a duct, B category;

—    installed in the downstream of a duct, C category;

—    installed in a duct, or with duct connection upstream and downstream, D category;

—    with one or several inlets/outlets;

—    installed in a system with a heat pump for domestic hot water or water for cooling or heating;

—    which can be used for supply or exhaust.

This document does not apply to:

—    fan assisted cowls which are tested according to EN 13141‑5;

—    mechanical supply and exhaust units which are tested according to prEN 13141‑7 or prEN 13141‑8.

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.
