Foreword
This European Standard (EN 14706:2005) has been prepared by Technical Committee CEN/TC 88 “Thermal
insulating materials and products”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by June 2006, and conflicting national standards shall be withdrawn at
the latest by June 2006.
This European Standard is one of a series of standards which specify test methods for determining
dimensions and properties of thermal insulating materials and products. It supports a series of product
standards for thermal insulating materials and products which derive from the Council Directive of
21 December 1988 on the approximation of laws, regulations and administrative provisions of the Member
States relating to construction products (Directive 89/106/EEC) through the consideration of the essential
requirements.
This standard contains the following 4 normative annexes:
Annex A — Modifications of and additions to the general test method for mineral wool products
Annex B — Modifications of and additions to the general test method for cellular glass products
Annex C — Modifications of and additions to the general test method for phenolic foam products
Annex D — Modifications of and additions to the general test method for polyethylene foam and flexible
elastomeric foam products
This European Standard has been prepared for products used to insulate building equipment and industrial
installations, but it may also be applied to products used in other areas.
A similar standard is available for testing of preformed pipe insulation EN 14707 Thermal insulating products
for building equipment and industrial installations — Determination of maximum service temperature for
preformed pipe insulation.

3 Terms and definitions
For the purposes of this European Standard, the following terms and definitions apply.
3.1
Maximum service temperature
highest temperature to which a thermal insulation product may be exposed at a given thickness and at which it
will continue to function within specified limits of performance
[prEN ISO 9229]
NOTE 1 The required performance may be in the areas of dimensional stability, thermal properties, and mechanical
properties as well as changes in appearance and resistance against creation of hazards such as internal self heating (see
Annexes A and C and possible requirements in the relevant product standard).
NOTE 2 In the present test procedure, which is used as a reference, the test specimen is exposed to a temperature
difference going from ambient to the maximum service temperature. This may not reflect the actual application conditions
when products are exposed to different temperatures on the two main faces, e.g. in multilayer systems or for faced
products where the facing may limit the maximum service temperature.
4 Principle
Measure thickness, length, and width after one sided heat treatment for a specified time period, at the
maximum service temperature, achieved using a specified rate of temperature increase. The thickness of the
test specimen is measured during heat treatment, and the length and width only after cooling to ambient
temperature.
NOTE The procedure may be an iterative process.

EN 14706:2005 (E)
Additional requirements for assessing the maximum service temperature of specific materials are described in
normative annexes to this European Standard or the relevant product standard or any other European
Technical Specification.
5 Apparatus
A general arrangement of the apparatus is indicated in figure 1 and comprises:
5.1 Flat square or circular hot plate, with a uniform temperature distribution in the measuring zone on the
hot face and a heat flux perpendicular to the face of the hot plate. The deviation from flatness of the hot plate
shall not exceed 1 mm in the measuring zone at ambient temperature.
The hot plate shall be capable of being controlled to within ± 2 % of a predetermined temperature or ± 10 °C
whichever is smaller.
The hot plate shall be capable of being heated at 50 °C/h and/or 300 °C/h.
5.2 Edge insulation, with a gap as small as possible (e.g. ≤ 1 mm/100 mm test specimen size) which will
permit free movement during the test of the test specimen and of the pressure plate.
5.3 Square or circular pressure plate, with the same dimensions as the test specimen exerting the
required load on the test specimen.
5.4 Device, e.g. electromechanical for measuring the thickness of the test specimen during the test to the
nearest 0,1 mm.
When determining the thickness of the test specimen the thermal movement of the apparatus (e. g. quartz
rod) shall be taken into account up to the maximum service temperature.
5.5 Temperature sensors (e.g. thermocouples) capable of recording the hot plate temperature to the
nearest ± 1 % in centigrade but not less than ± 1 °C, which are placed within grooves on the hot plate.
