Foreword
This European Standard has been prepared by Technical Committee CEN/TC 156 "Ventilation for buildings",
the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by April 2002, and conflicting national standards shall be withdrawn at
the latest by April 2002.
This European Standard is a part of a series of standards for air handling units used for ventilation and air
conditioning of buildings for human occupancy. It considers the ratings and the performance of air handling
units as a whole, the requirements and performance of specific components and sections of air handling
units including hygiene requirements. It is supported by the standard for mechanical performance, EN
1886:1998. The position of this standard in the field of mechanical building services is shown in Figure 1.

Annex A is normative. Annexes B and C are informative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark,
Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal,
Spain, Sweden, Switzerland and the United Kingdom.
1 Scope
This European Standard specifies requirements and testing for ratings and performance of air handling units
as a whole.
It also specifies requirements, 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 standalone components.
This standard is applicable both to standardized 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.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications.
These normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply
to this European Standard only when incorporated in it by amendment or revision. For undated references
