Foreword
This document (CEN/TS 15548-1:2011) has been prepared by Technical Committee CEN/TC 89 “Thermal
performance of buildings and building components”, the secretariat of which is held by SIS.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria, Croatia, Cyprus,
Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,
Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia,

Introduction
This technical specification is an interim solution to the need for a standard to complement EN 12667:2001 in
the approximate temperature range 100 °C to 850 °C.
The technical specification is chosen to publish the knowledge gained in the field of measuring thermal
conductivity at elevated temperature now, as the finalisation of a standard is a complex matter requiring
further investigations.
Among existing apparatus for steady state thermal testing, the guarded hot plate can be operated at selected
mean temperatures over the temperature range -100 °C to 850 °C. In general, these apparatus exist in three
forms covering roughly the following temperature ranges -100 °C to ambient, ambient to 100 °C and above
100 °C. However, it has been found that it is not possible to achieve the uncertainties of ± 2 % claimed as
achievable for the low and ambient temperature forms when using the high temperature version in accordance
with ISO 8302. More realistic figures adopting the method and procedures detailed in this document are ± 5 %
up to 450 °C and ± 7 % at temperatures above 450 °C.
Many issues are more difficult at high temperatures. There are design issues due to apparatus material
stability, the level of temperature measurement uncertainty is higher than at ambient temperatures and there
is also greater degradation in the performance of temperature sensors when operated at high temperatures,
requiring calibration checks to be more frequent. At high temperatures, it is more likely to get hot spots on a
plate due to non-uniformity of a heater; these could be near temperature sensors and give false readings. Any
air gaps will have greater heat flow across them due to radiation heat exchange and finally provisions for
specimen expansion or shrinkage are needed.
Due to the above considerations the following clauses of EN 12667:2001 have been expanded and detailed:
