1254/2014 - Commission Delegated Regulation (EU) No 1254/2014 of 11 July 2014 supplementing Directive 2010/30/EU of the European Parliament and of the Council with regard to energy labelling of residential ventilation units

This European standard 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, prEN 13141 6 and prEN 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 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 European Standard specifies requirements and testing for ratings and performance of air handling units as a whole. It also specifies requirements, recommendations, classification, and testing of specific components and sections of air handling units. For many components and sections it refers to component standards, but it also specifies restrictions or applications of standards developed for stand alone components.
This standard is applicable both to standardised designs, which may be in a range of sizes having common construction concepts, and also to custom-design units. It also applies both to air handling units, which are completely prefabricated, and to units which are built up on site. Generally the units within the scope of this standard include at least a fan, a heat exchanger and an air filter.
This standard is not applicable to the following:
a)   air conditioning units serving a limited area in a building, such as fan coil units;
b)   units for residential buildings;
c)   units producing ventilation air mainly for a manufacturing process.

This document specifies requirements and testing for rating and performance of Non Residential Ventilation Units, NRVU’s, specifically Air Handling Units (AHU’s). It specifies requirements, classifications and testing of components and sections of air handling units.
This document applies to tests in a laboratory and in situ. This document is applicable both for mass produced air handling units and tailor-made Air Handling Units.
This document applies to AHU and individual sections of AHU with the designed air flow > 250 m3 · h−1. This document applies to UVU's with additional air treatment components in addition to filtration.
This standard does not include:
-   residential unidirectional and bidirectional ventilation units;
-   nonresidential unidirectional ventilation units which consist of only a casing, a fan with or without filter.
NOTE 1   Residential ventilation units are covered by EN 13142.
NOTE 2   Nonresidential unidirectional ventilation units which consists only casing, fan with or without filter are covered by EN 17291.

ISO 16890-3:2016 specifies the test equipment and the test methods used for measuring the gravimetric efficiency and resistance to air flow of air filter for general ventilation.
It is intended for use in conjunction with ISO 16890‑1, ISO 16890‑2 and ISO 16890‑4.
The test method described in this part of ISO 16890 is applicable for air flow rates between 0,25 m3/s (900 m3/h, 530 ft3/min) and 1,5 m3/s (5 400 m3/h, 3 178 ft3/min), referring to a test rig with a nominal face area of 610 mm × 610 mm (24 in × 24 in).
ISO 16890 (all parts) refers to particulate air filter elements for general ventilation having an ePM1 efficiency less than or equal to 99 % and an ePM10 efficiency greater than 20 % when tested as per the procedures defined within ISO 16890 (all parts).
Air filter elements outside of this aerosol fraction are evaluated by other applicable test methods. See ISO 29463 (all parts).
Filter elements used in portable room-air cleaners are excluded from the scope of this part of ISO 16890.
The performance results obtained in accordance with ISO 16890 (all parts) cannot by themselves be quantitatively applied to predict performance in service with regard to efficiency and lifetime.

ISO 16890-2:2016 specifies the aerosol production, the test equipment and the test methods used for measuring fractional efficiency and air flow resistance of air filters for general ventilation.
It is intended for use in conjunction with ISO 16890‑1, ISO 16890‑3 and ISO 16890‑4.
The test method described in this part of ISO 16890 is applicable for air flow rates between 0,25 m3/s (900 m3/h, 530 ft3/min) and 1,5 m3/s (5 400 m3/h, 3 178 ft3/min), referring to a test rig with a nominal face area of 610 mm × 610 mm (24,0 inch × 24,0 inch).
ISO 16890 (all parts) refers to particulate air filter elements for general ventilation having an ePM1 efficiency less than or equal to 99 % and an ePM10 efficiency greater than 20 % when tested as per the procedures defined within ISO 16890 (all parts).
NOTE The lower limit for this test procedure is set at a minimum ePM10 efficiency of 20 % since it will be very difficult for a test filter element below this level to meet the statistical validity requirements of this procedure.
Air filter elements outside of this aerosol fraction are evaluated by other applicable test methods, (see ISO 29463 (all parts)).
Filter elements used in portable room-air cleaners are excluded from the scope.
The performance results obtained in accordance with ISO 16890 (all parts) cannot by themselves be quantitatively applied to predict performance in service with regard to efficiency and lifetime.

ISO 16890-1:2016 establishes an efficiency classification system of air filters for general ventilation based upon particulate matter (PM). It also provides an overview of the test procedures, and specifies general requirements for assessing and marking the filters, as well as for documenting the test results. It is intended for use in conjunction with ISO 16890‑2, ISO 16890‑3 and ISO 16890‑4.
The test method described in this part of ISO 16890 is applicable for air flow rates between 0,25 m3/s (900 m3/h, 530 ft3/min) and 1,5 m3/s (5 400 m3/h, 3 178 ft3/min), referring to a test rig with a nominal face area of 610 mm × 610 mm (24 inch × 24 inch).

ISO 16890-4:2016 establishes a conditioning method to determine the minimum fractional test efficiency.
It is intended for use in conjunction with ISO 16890‑1, ISO 16890‑2 and ISO 16890‑3, and provides the related test requirements for the test device and conditioning cabinet as well as the conditioning procedure to follow.

The performance results obtained in accordance with ISO 16890 (all parts) cannot by themselves be quantitatively applied to predict performance in service with regard to efficiency and lifetime.
The results from this part of ISO 16890 may also be used by other standards that define or classify the fractional efficiency in the size range of 0,3 μm to 10 μm when electrostatic removal mechanism is an important factor to consider, for example ISO 29461.
