General Information
Overview
EN ISO 13787:2003 (CEN) - Thermal insulation products for building equipment and industrial installations - defines the procedure for the determination and verification of the declared thermal conductivity of thermal insulating materials and products as a function of temperature. It specifies how manufacturers must present thermal conductivity values (curve or table), how measurements are made and verified, and includes informative annexes (A, B, C) with alternative comparison and statistical methods.
Key topics and technical requirements
- Declared thermal conductivity curve or table: Manufacturer provides a proposed curve or table showing thermal conductivity versus mean temperature, conditioned at standard atmosphere (23 °C, 50% RH).
- Measurement methods: Measurements performed in accordance with ISO 8301, ISO 8302 or EN 12667 for flat specimens, and EN ISO 8497 for cylindrical specimens.
- Temperature measurement rules:
- Measurements at a minimum of three mean temperatures.
- For mean temperatures up to 500 °C, measurements at intervals no greater than 100 K; for >500 °C, intervals up to 200 K.
- No extrapolation beyond measured range; round results to 0.001 W/(m·K).
- Test specimen conditioning: Specimens shall be aged where necessary or an ageing correction applied.
- Temperature difference: For flat specimens, hot–cold face difference 10 K to 40 K (choose for best accuracy); for cylindrical, at least 10 K.
- Verification procedure (summary):
- Select three random samples; measure first specimen and compare to proposed curve.
- If measured values ≤ proposed values → pass.
- If any measured value ≥ proposed value by ≥10% → fail.
- If intermediate exceedances (<10%), measure two more specimens (one from each remaining sample), convert/average results and re-evaluate per standard rules.
- Informative annexes:
- Annex A: curve-comparison alternative;
- Annex B: optional statistical method to establish declared curve from many measurements;

9229:1997 and the following apply.
3.1
reference mean temperature
mean temperature selected for use as the basis for physical property measurement and expression of data for
those materials where physical properties change with temperature
3.2
declared value
value declared by a manufacturer which is derived from measured values under specified conditions and rules
3.3
declared thermal value
expected value of a thermal property of a building material or product
— assessed from measured data at reference conditions of temperature and humidity;
— given for a stated fraction and confidence level according to the determination method in this standard;

3.4
declared thermal conductivity curve
curve giving the thermal conductivity at different temperatures for a material or product conditioned in equilibrium
with a standard atmosphere (23 °C, 50 % relative humidity) based on the declared thermal values
4 Principles for the determination of declared thermal conductivity
The manufacturer shall present his proposed declared thermal conductivity of the material or product in the form of
a curve as a function of the mean temperature or a table with a number of values in accordance with 5.1.
The product shall then be subjected to a test according to clause 5, with test specimens representative of the
product.
If the test is passed, the proposed declared thermal conductivity curve or table becomes the declared thermal
conductivity curve or table.
NOTE 1 An alternative procedure to the one given in the standard is given in annex A.
NOTE 2 An optional statistical method to establish the declared thermal conductivity curve is given in annex B.
5 Determination and verification of declared thermal conductivity
5.1 Measurement of thermal conductivity
The test specimens shall be aged, if necessary, before measurements are made. As an alternative, a correction
factor for ageing shall be applied.
NOTE Ageing procedures are found in product specifications, where relevant.
Measurements shall be carried out in accordance with ISO 8301, ISO 8302 or EN 12667 for flat test specimens and
EN ISO 8497 for cylindrical test specimens.
The temperature difference between the hot and cold faces shall range from 10 K to 40 K for flat test specimens.
The temperature difference shall be chosen to maximize the accuracy of the measurement. For cylindrical
specimens, tested in accordance with EN ISO 8497, these requirements on temperature difference do not apply,
but the temperature difference shall not be smaller than 10 K.
Measurements shall be made at three different mean temperatures at least.
For mean temperatures up to 500 °C, the curve determined in the test shall be based upon measurements at
intervals of a maximum of 100 K, over the whole service temperature range stated by the manufacturer.
Thermal conductivity shall also be measured at temperatures close to inflexion points or other irregularities of the
curve.
For mean temperatures greater than 500 °C, the curve determined in the test shall be based upon measurements
at intervals of a maximum of 200 K.
No extrapolation of test results beyond the measured temperature range is permitted. The measured thermal
conductivities shall be rounded up to the nearest 0,001 W/(m⋅K).
The results shall be expressed either by a temperature/thermal conductivity curve or by a table. The comparison
with the proposed curve or table is only made at the temperatures of measurement.
5.2 Procedure for verification
Select three different samples. Take the test specimens from these samples at random, as required.
Measure the thermal conductivity of the test specimen from the first sample in accordance with the method
described in 5.1.
Compare the results of the measurements with the values obtained from the proposed curve or table.
— If the measured values are all less than or equal to the thermal conductivities derived from the proposed curve
or table, the test is passed and the proposed curve or table becomes the declared curve or table.
— If one or more of the measured values exceeds the corresponding thermal conductivity of the proposed curve or
table by 10 % or more, the test has failed.
— If there are measured values above the values on the proposed curve or in the table but none of them exceeds
the corresponding thermal conductivity by 10 %, then two new test specimens shall be measured in accordance
with the method described in 5.1, one specimen being taken from each of the two remaining samples.
For temperatures £ below 100 °C, measure the thermal conductivities of the second and third specimen at
temperatures within ± 5 K of the values measured for the first specimen. Increase this to ± 10 K for temperatures
above 100 °C.
If none of the new measurements exceeds the proposed curve or table by 10 % or more, the measured thermal
conductivities shall be converted to the temperatures at which the measurements for the first curve were made,
using the slope of the first curve to make the conversion.
Results of the measurements above the proposed curve or the value in the table by 10% or more shall constitute a
failure of the test.
Calculate the values of thermal conductivity at the corresponding temperatures by calculating the mean of the three
values measured or converted at each temperature.
— If all these new mean values are lower than or equal to the corresponding thermal conductivities of the
proposed declared curve, the test has passed, in which event the proposed declared curve or table becomes
the declared curve or table.
—
If one or more of the new mean values is higher than the corresponding thermal conductivity of the proposed
declared curve or table, the test has failed.
The verification procedure is described in the flow chart in Figure 1 and illustrated in annex C.
