What is BS EN 13142 about?
BS EN 13142 discusses residential ventilation with performance characteristics focus. BS EN 13142 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. The performance characteristics include aspects such as comfort conditions of temperature, air velocity, humidity, hygiene, and sound; in the occupied zone.
BS EN 13142 covers the following the codification classification:
- Unidirectional mechanical supply and exhaust residential ventilation units according to EN 13141-4:2021, EN 13141-6:2014, and EN 13141-11
- Ducted mechanical bidirectional residential ventilation units according to EN 13141-7:2021
- Non-ducted mechanical bidirectional residential ventilation units according to EN 13141-8:2020
Note 1: BS EN 13142 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.
Note 2: BS EN 13142 does not cover requirements raised by European Directives (e.g., low voltage directive, EMC directive) and other requirements such as corrosion, reaction to fire and snow penetration.
Who is BS EN 13142 for?
BS EN 13142 on ventilation for buildings (components/products for residential ventilation) is useful for:
- Manufacturers of ventilation systems and components
- Product design engineers
- Civil Engineers
- Architects
- Builders
Why should you use BS EN 13142?
Ventilation for buildings is necessary to balance temperature, moisture, odour, and air quality. Issues with ventilation systems can compromise the physical and mental health of building occupants.
A combination of components and/or products is required to provide ventilation. These components/products interact to circulate fresh air in a building. 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.
BS EN 13142 guides you with 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.
BS EN 13142 provides you with a classification for balanced ventilation units which may be used for the determination of minimum and optional product characteristics in national building regulations and standards.
What’s changed since the last update?
BS EN 13142:2021 supersedes BS EN 13142:2013, which is withdrawn. BS EN 13142:2021 includes some technical changes with respect to BS EN 13142:2013. These include:
- Aspects of outdoor and indoor mixing have been added in 5.1
- Unidirectional ventilation units have been added in 5.6 and fans used in residential ventilation units have been removed
- 8 has been updated with classification aspects for energy and acoustics
- 9 has been updated with data input, declaration, leakage in 5.9.4.2, energy in 5.9.6, nominal temperature performance factor, NTPF has been deleted, classification of humidity ratio has been reviewed and acoustic classification at a reference volume flow
- 5.10 has been updated with link to EN 13141-8:2020 with air flow sensitivity classification, classification of humidity ratio has been reviewed and nominal temperature performance factor, NTPF, has been deleted
