Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 162, Doors, windows and curtain walling.
This second edition cancels and replaces the first edition (ISO 6612:1980), which has been technically
revised.
The main changes are as follows:
— pedestrian door sets have been added to the scope;
— the title has been revised;
— this document has been adapted to the current state of the art using Reference [1];
— the technical content has been precised.
Any feedback or questions on this document should be directed to the user’s national standards body. A

INTERNATIONAL STANDARD ISO 6612:2023(E)
Windows and doors — Resistance to wind load — Test
method
1 Scope
This document specifies test method to determine the resistance to wind load of completely assembled
windows and pedestrian door sets of any materials when exposed to positive or negative test pressures.
This test method is designed to take account of conditions in use, when the window or door set
is installed in accordance with the manufacture's specification and the requirements of relevant
International Standards and codes of practice.
This document does not apply to joints between the window or door frame and the building construction.
This document is not intended to evaluate strength of the glass.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.
ISO 6613, Windows and doors — Air permeability — Test method
ISO 22496, Windows and pedestrian doors — Vocabulary
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 22496 and the following apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at https:// www .electropedia .org/
3.1
closed
closing condition where movable parts rest in or at the fixed parts in a way in which the movable parts
can be fastened (3.2) [latched (3.3) and/or locked (3.4)]
3.2
fastened
closing condition where the movable part is restrained at one or more points by latching and/or locking
3.3
latched
fastened (3.2) condition where the movable part is returned to its closed (3.1) position and restrained
Note 1 to entry: The movable part is restrained by either:
a) a self-engaging fastener, or
b) a roller catch, or
c) a latch.
3.4
locked
fastened (3.2) condition where the movable part is further restrained in the closed (3.1) position by
additional operations to engage integrated locking devices which affect the product’s characteristics
Note 1 to entry: The restraining in the closed position is done by additional operations of, for example, handle,
key, automatic devices or electronic devices.
Note 2 to entry: Integrated locking devices are, for example, nut bolts or deadbolts.
3.5
frontal displacement
movement of a point on a frame member measured normal to the member
3.6
frontal deflection
maximum frontal displacement (3.5) of a frame member minus half the sum of the frontal displacements
at each end of the member
3.7
relative frontal deflection
frontal deflection (3.6) of a frame member divided by the length of the member over which the frontal
deflection was measured
Note 1 to entry: The length of the member over which the frontal deflection was measured is for example, the
distance between the ends of the member.
3.8
test pressure
difference between the static air pressures inside and outside of the test chamber
Note 1 to entry: The test pressure is positive if the static air pressure inside the chamber of the test apparatus is
higher than that outside the test chamber.
Note 2 to entry: The test pressure is negative if the static air pressure inside the chamber of the test apparatus is
lower than that outside the test chamber.
Note 3 to entry: The intended “outside” of the specimen shall be facing to the side, from where the positive
pressure is applied.
For the purpose of these tests, three sets of test pressure are defined:
