4 Requirements
4.1 General
Product properties shall be tested in accordance with Clause 5. To conform to this standard, products
shall meet the requirements of 4.2 and 4.3 as appropriate.
This European Standard gives an example of a manufacturer’s performance chart (declared thermal
resistance related to the declared density range) which can be adapted for any application, see Annex K.
NOTE Different applications can require different classes for settlement. One test result of a product property
is the average of the measured values on the number of test specimens given in Table 6.
4.2 For all applications
4.2.1 Thermal resistance and thermal conductivity
Thermal resistance and thermal conductivity shall be based upon measurements carried out in
accordance with EN 12667 and/or EN 12939 for thick products and 5.3.2.
The thermal values shall be determined in accordance with Annex A, 5.1 and 5.3.2 and declared by the
manufacturer, according to the following:
— the reference mean temperature shall be 10 °C;
— the values shall be measured in dry conditions but the values declared shall be given for the
product when conditioned at 23 °C and a relative humidity of 50 % (see 5.2);
— the thermal resistance, R , shall always be declared. The thermal conductivity, λ , shall be declared
D D
where possible;
— the thermal resistance, R , and the thermal conductivity, λ , shall be given as limit values
D D
representing at least 90 % of the production determined with a confidence level of 90 %;
— the measured values shall be expressed to three significant figures;
— the declared thermal resistance, R , shall be calculated from the declared thermal insulation
D
thickness and the corresponding λ taking into account the declared settlement s (see NOTE
D,
D
below);
— the value of thermal conductivity λ shall be rounded upwards to the nearest 0,001 W/(m × K) and
D
declared in levels with steps of 0,001 W/(m × K); the thermal conductivity value shall be declared;
— the value of thermal resistance, R , shall be rounded downwards to the nearest 0,05 m K/W and
D
declared in levels with steps of 0,05 m K/W; since LFCI can be installed at a variety of thickness
(e.g. in a void or cavity) a table giving declared R-values at different thickness shall be used for
marking and labelling.
NOTE The thermal resistance for loose-fill cellulose insulation is declared by the manufacturer in accordance
with the declared density range using thermal conductivity measurements taken at densities across the declared
density range and the worst result used as the declared value (see Annex K).

convection or when evaluating the sound insulation capability.
4.3.8 Continuous Glowing Combustion
!When declared, the continuous smouldering combustion shall be tested in accordance with
EN 16733.
If the product does not show propensity for continuous smouldering combustion, NoS shall be included
in the designation code.
If the product shows propensity for continuous smouldering combustion, S shall be included in the
product designation code."
4.3.9 Sound absorption
The sound absorption coefficient shall be determined in accordance with EN ISO 354 but always
without a plenum. The sound absorption characteristics shall be calculated in accordance with
EN ISO 11654 using the values for the practical sound absorption coefficient, α , at the frequencies:
p
125 Hz, 250 Hz, 500 Hz, 1 000 Hz, 2 000 Hz and 4 000 Hz and the single number value for α (weighted
w
sound absorption coefficient).
α and α shall be rounded to the nearest 0,05 (α > 1 shall be expressed as α = 1) and declared in
p w p p
levels with steps of 0,05. No test result (α and α ) shall be lower than the declared level.

4.3.10 Reaction to fire of product in standardized assemblies simulating end-use applications
Reaction to fire classification of products in standardized assemblies simulating end-use applications
shall be determined in accordance with EN 13501-1 with the basic mounting and fixing rules given in
Annex J.
This classification offers the opportunity to give a complementary and optional declaration on reaction
to fire for standard test configurations of assemblies which include the insulation product.
Detailed information about the test conditions and the field of application of the classification as stated
in the reaction to fire classification report shall be given in the manufacturer's literature.
5 Test methods
5.1 Sampling
Sufficient product should be sampled in order to perform all the required tests of the same batch of
product.
5.2 Conditioning
For test samples, no conditioning is needed unless otherwise specified in the test standard. In case of
dispute, the test samples shall be stored at (23 ± 2) °C and (50 ± 5) % relative humidity for at least
6 weeks prior to testing. For FPC no special conditioning of the test samples is needed.
Except for 5.3.2, test specimens shall be conditioned in an atmosphere of (23 ± 2) °C and (50 ± 5) %
relative humidity until stabilization at constant weight is achieved. Stabilization is obtained when the
relative change in weight does not exceed 0,5 % between two consecutive weekly measurements. In
case of dispute, the following stepwise procedure shall be carried out:
— step 1 (dry reference): The specimens are conditioned for 72 h at (70 ± 2) °C, in an oven
ventilated with an air taken at (23 ± 2) °C and (50 ± 5) % relative humidity, and then weighed. The
mass of the test specimen at step 1 is m .
23,dry
— step 2 (normal reference): After conditioning according to step 1, the specimens are further
conditioned in an atmosphere of (23 ± 2) °C and (50 ± 5) % relative humidity until stabilization,
and then weighed. Stabilization, by definition, takes at least 6 weeks with some additional time so
that the relative change in moisture does not increase by more than 5 % between two consecutive
weekly measurements. The mass of the test specimen at step 2 is m .
23,50
Moisture content, u , expressed in kilogram per kilogram, shall be determined by weighing the
23,50
specimens at each step with an accuracy of 0,1 g, and calculated using Formula (1)
