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

This document was prepared by Technical Committee ISO/TC 162, Doors, windows and curtain walling.
This second edition cancels and replaces ISO 6613:1980 and ISO 8272:1985, which have 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 on the basis of 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 6613:2023(E)
Windows and doors — Air permeability — Test method
1 Scope
This document specifies the test method to determine the air permeability of completely assembled
windows and pedestrian door sets of any material, 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 manufacturer’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.
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.

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:

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
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.
3.6
air permeability
amount of air passing through all joints between casement or leaf and frame profiles of a test specimen
caused by the test pressure (3.5)
3.7
opening joint
line of discontinuity between either a frame and its matched component or two components which can
be opened by means of their building hardware
Note 1 to entry: Conventionally, this discontinuity is as seen from the opening face of the test specimen.
Note 2 to entry: See Figures 1 to 6.
3.8
length of opening joint
length of the line of discontinuity between either a frame and its matched component or two components
which can be opened by means of their building hardware
Note 1 to entry: The length of joint should be expressed in metres.
Note 2 to entry: Actual length of gaskets or seals fitted into the underlying profiles of the components or joints of
components built into opening parts are not relevant.
Note 3 to entry: See Figures 1 to 6.
3.9
overall area
area of the test specimen measured parallel to the glazing or the leaf
Note 1 to entry: The overall area should be expressed in square metres.
Note 2 to entry: See Figures 1 to 6.
4 Principles of test
The test consists of the application of a defined series of test pressures (positive and negative) and at
each test pressure measurement of the air permeability with a suitable test device.
5 Test apparatus
5.1 A chamber with an open side to which the test specimen can be fitted. It shall be constructed so
as to be able to withstand the test pressures without deflecting to an extent likely to influence the test
results.
5.2 Means for applying controlled test pressure to the test specimen.
5.3 Means of producing rapid changes in test pressure, controlled within defined limits.
5.4 Instrument suitable for measuring the quantity of air flow into or out of the chamber with an
3 3
accuracy of ±5 % of the measured value for air flows greater than 1 m /h and an accuracy of ±0,05 m /h
for air flows equal to or smaller than 1 m /h.
NOTE 1 Accuracy is equal to plus minus the sum of the amount of the error plus the amount of the expanded
measurement uncertainty. For values of both error and expanded measurement uncertainty, refer to the last
calibration certificate of the instrument.
NOTE 2 For vocabulary of metrology, see ISO/IEC Guide 99.
5.5 Means of measuring the test pressure applied across the test specimen, within an accuracy
of ±5 %.
5.6 Means of sealing all joints of the test specimen, when required.
6 Preparation of the test specimen
The test specimen shall be fixed as intended for use without any twists or bends which can influence
the test results. The test specimen shall be fully operable.
The test specimen shall be cleaned and its surfaces shall be dry.
Ventilation devices, if any, shall be taped over, except when it is required to determine the amount of air
flow through such devices.
7 Test procedure
7.1 Preliminaries
The ambient temperature and humidity close to the test specimen shall be within the range of 10 °C to
30 °C and 25 % to 75 % RH, and the test specimen shall be conditioned thus for at least 4 h immediately
before testing.
Temperature shall be measured to within ±3 °C and relative humidity to within ±5 %. Atmospheric
pressure shall be measured to within ±1 kPa.
The test pressure shall be applied in steps of 50 Pa up to 300 Pa and from 300 Pa in steps of 150 Pa.
