Windows and doors — Resistance to wind load — Test method

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.

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

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.
