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 12567-1 was prepared by Technical Committee ISO/TC 163, Thermal performance and energy use in the
built environment, Subcommittee SC 1, Test and measurement methods.
This second edition cancels and replaces the first edition (ISO 12567-1:2000), which has been technically
revised.
ISO 12567 consists of the following parts, under the general title Thermal performance of windows and
doors — Determination of thermal transmittance by the hot-box method:
⎯ Part 1: Complete windows and doors
1)
⎯ Part 2: Roof windows and other projecting windows

1) It is intended that, upon revision, the main element of the title of Part 2 will be aligned with the main element of the title
of Part 1.

Introduction
The method specified in this part of ISO 12567 is based on ISO 8990. It is designed to provide both
standardized tests, which enable a fair comparison of different products to be made, and specific tests on
products for practical application purposes. The former specifies standardized specimen sizes and applied
test criteria.
The determination of the aggregate thermal transmittance is performed for conditions which are similar to the
actual situation of the window and door in practice.

The uncertainty analysis for hot boxes is given in Annex F.

4 Principle
The thermal transmittance, U, of the specimen is measured by means of the calibrated or guarded hot-box
method in accordance with ISO 8990.
The determination of the thermal transmittance involves two stages. Firstly, measurements are made on two
or more calibration panels with accurately known thermal properties, from which the surface coefficient of the
heat transfer (radiative and convective components) on both sides of the calibration panel with surface
emissivities on average similar to those of the specimen to be tested and the thermal resistance of the
surround panel are determined. Secondly, measurements are made with the window or door specimens in the
aperture and the hot-box apparatus is used with the same fan settings on the cold side as during the
calibration procedure.
The surround panel is used to keep the specimen in a given position. It is constructed with outer dimensions
of appropriate size for the apparatus, having an aperture to accommodate the specimen (see Figures 1 to 4).
The principal heat flows through the surround panel and the calibration panel (or test specimen) are shown in
Figure 5. The boundary edge heat flow due to the location of the calibration panel in the surround panel is
determined separately by a linear thermal transmittance, Ψ.
The procedure in this part of ISO 12567 includes a correction for the boundary edge heat flow, such that
standardized and reproducible thermal transmittance properties are obtained.
The magnitude of the boundary edge heat flow as a function of geometry, calibration panel thickness and
thermal conductivity is determined by tabulated values given in Annex B or is calculated in accordance with
ISO 10211.
Measurement results are corrected to standardized surface heat transfer coefficients by an interpolation or
analytical iteration procedure, derived from the calibration measurements.
Measurements are taken (e.g. pressure equalization between the warm and cold side or sealing of the joints
on the inside) to ensure that the air permeability of the test specimen does not influence the measurements.

ISO 12567-1:2010(E)
5 Requirements for test specimens and apparatus
5.1 General
The construction and operation of the apparatus shall comply with the requirements specified in ISO 8990,
except where modified by this part of ISO 12567. To make heat transfer measurements on the specimen, the
specimen shall be mounted in a suitable surround panel and the heat flow shall be deduced through it by
subtracting that through the surround panel from the total heat input. Also, the test element and the surround
panel are usually of different thickness, such that there is disturbance of heat flow paths and temperatures in
the region of the boundary between the two. The test shall be carried out such that edge corrections can be
applied.
5.2 Surround panels
The surround panel acts as an idealized wall with high thermal resistance and holds the window or door in the
correct position and separates the warm box from the cold box. The surround panel shall be large enough to
cover the open face of the guard box in the case of a guarded hot-box apparatus or the open face of the hot
box in the case of a calibrated hot-box apparatus.
The surround panel shall be not less than 100 mm thick or the maximum thickness of the specimen,
whichever is the greater, and it shall be constructed with core material of stable thermal conductivity not
greater than 0,04 W/(m⋅K). An appropriate aperture shall be provided to accommodate the calibration panel or
test specimen (see Figures 1, 2, 3 and 4). Sealed plywood facing or plastic sheet on either side of the
surround panel to provide rigidity is permitted. No material of thermal conductivity higher than 0,04 W/(m⋅K)
(other than non-metallic thin tape) shall bridge the aperture. The surfaces of the surround panel and baffle
plates shall have a high emissivity (> 0,8).
5.3 Test specimens
For general applications, specimen sizes may be typical of those found in practice. To ensure consistency of
measurement, the specimen should be located as follows.
The window system shall fill the surround panel aperture. The internal frame face shall be as close to the face
of the surround panel as possible, but no part shall project beyond the surround panel faces on either the cold
or warm sides, except for handles, rails, fins or fittings which normally project (see Figure 1).
The door system may be mounted on either inside the surround panel (see Figures 2 and 4) or on the warm
face (see Figure 3), according to the instructions and specifications given by the manufacturer.
It is recommended that the aperture be placed centrally in the surround panel and at least 200 mm from the
inside surfaces of the cold and hot boxes, in order to avoid or limit edge heat flow corrections related to the
perimeter of the surround panel (see Figure 6).
For standardized test applications, the overall sizes recommended are indicated in Table 4, or they shall
conform to the size required by national standards or other regulations.

In any case, the area of aperture shall be not less than 0,8 m , for reasons of accuracy. The perimeter joints
between the surround panel and the specimen shall be sealed on both sides with tape, caulking or mastic
material.

5.4 Calibration panels
Calibration panels shall be of a size similar to the test specimen (within ± 40 % in height and width of the test
specimen). They are required to set up specified test conditions, to determine the surface coefficients of heat
transfer and to establish the th
