European foreword
This document (prEN 12444:2020) has been prepared by Technical Committee CEN/TC 33 “Doors,
windows, shutters, building hardware and curtain walling”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 12444:2000.
Compared with EN 12444:2000, the following changes have been made:
— normative references were updated;
— references to the classification standard EN 12424:2000 were deleted as the classification of the
characteristic resistance to wind load has been transferred to prEN 13241:2020, and references to
prEN 13241:2020 have been added accordingly.
This document is one of a series of performance standards identified within the product standard
prEN 13421:2020.
This document as well as relevant national regulations and standards will enable the actual exposure
levels to be determined for the individual locations of the products.
As during the revision of this document the test procedures haven’t been changed, existing test results
remain valid (historical data).

1 Scope
This document specifies the test method and/or calculation of resistance to wind load for industrial,
commercial and garage doors and gates according prEN 13241:2020 in a closed position.
For the purposes of this document the term ‘door’ is used as a general term for ‘industrial, commercial
and garage doors and gates’ unless clearly stated.
2 Normative references

undated references, the latest edition of the referenced document (including any amendments) applies.

4 Principle of test
The principle of test is to apply a pressure differential across the test specimen, to determine failure.
Full size specimen shall be tested. If it is impossible or uneconomical to achieve full scale testing, parts
of door assemblies (elements E) shall be tested for calculating a result for a full door calculation.
Whether testing full door assemblies or elements of doors the maximum height/width dimension which
is critical to the wind load resistance (e.g. width for vertically operating doors) shall be tested for each
design criteria.
In order to provide information for the extrapolation of results for smaller sizes, at least one additional
test shall be completed on an alternative dimension for each design criterium.
5 Apparatus
A surround for the test specimen or elements shall be prepared, it shall be able to withstand the
pressures applied during the test without deflecting to an extent, likely to impair jointing or to impose
bending stresses, that might effect the performances of test specimen.
6 Preparation of test specimen or elements (E)
6.1 The test specimen or elements shall be installed in the test position as advised by the
manufacturer, taking into account the frame tracks and any wind resisting devices.
6.2 The test specimen or elements shall consist of parts that in detail conform to the production level
of quality. Whenever possible the test specimen should be newly made. Doors and parts in stock are to
be regarded as newly made if they fully comply with the specification of the running production.
7 Test procedure
7.1 Testing of complete doors
7.1.1 Loads applied to the sample should be in accordance with Annex B, Table B.1 and Figures B.1 to
B.3.
7.1.2 An evenly distributed load or pressure may be applied to the surface. This can be achieved in
various ways, for example, but not restricted to:
a) Air — pressurized chamber, in which case steps shall be taken to eliminate all air leakage on the
product and its attachment to the supporting construction;
b) Bags filled with sand or water distributed over the surface of the test sample, see Annex B;
c) Air — pressurized bags applied across the whole surface between a fixed rigid surface, for example
the floor and the surface of the test sample.
7.2 Testing of individual or collective elements
7.2.1 Uniformly distributed loads shall be applied in the same manner as described in 7.1.2 in gradual
steps and the effect upon deflection of the product, permanent distortion, engagement within the door
frame and ultimate failure shall be recorded after removing the loading when considered necessary
(see Annex A). The original sub-assembly mass and self-deflection shall be taken into account.
NOTE For elements which contain only completely homogenous material a central point loading can be used
as an alternative to uniformly distributed loading.
7.2.2 To calculate the resistance for the whole door assembly, according to the example in Annex A
the strength of components may be individually tested to failure by applying a load in the same
direction as will result from an applied windload.
NOTE The whole door can contain elements incorporating features such as windows or pass doors.
7.2.3 To ensure that production methods and material consi
