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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 12567-2 was prepared by Technical Committee ISO/TC 163, Thermal performance and energy use in the
built environment, Subcommittee SC 1, Test and measurement methods.
ISO 12567 consists of the following parts, under the general title Thermal performance of windows and
doors — Determination of thermal transmittance by hot box method:
⎯ Part 1: Complete windows and doors
⎯ Part 2: Roof windows and other projecting windows.

ISO 12567-2:2005(E)
Introduction
This part of ISO 12567 should be read together with ISO 12567-1:2000 Thermal performance of windows and
doors — Determination of thermal transmittance by hot box method — Part 1: Complete windows and doors.
These two parts were jointly developed by ISO and CEN. They are designed to provide standardised thermal
transmittance test values, to enable product comparisons to be made. ISO 12567-1:2000 specifies
standardised specimen sizes and applied test criteria.
It is recognised that the thermal performance of products will vary with heat flow direction and so it is
preferable to test these products at the orientation in which they will be installed. However, as there are only a
few hot boxes capable of carrying out such measurements, this measurement procedure specifies that it is
acceptable to measure the thermal transmittance of roof windows mounted vertically to facilitate the fair
comparison of products.
It should be noted that measurements with the specimen mounted vertically will generally produce U-values
lower than those measured at other orientations with heat flow up. An alternative to measuring at the actual
orientation that will be used in practice is to carry out calculations of convective and radiant heat transfer using
the procedures specified in ISO 15099, ISO 10077-1, ISO 10077-2 and EN 673.
