Annex A
(normative)
Determination of the declared values of thermal resistance and thermal
conductivity
A.1 Introduction
It is the responsibility of the manufacturer to determine the declared value of thermal resistance and thermal
conductivity. He will have to demonstrate conformity of the product to its declared value. The declared value of
thermal resistance and thermal conductivity of a product are the expected value of the property during an
economically reasonable working life under normal conditions, assessed through measured data at reference
conditions.
According to 4.2 and Clause 8 the declaration is given in the form of one or more performance charts worked
out according to Annex F, which requires the manufacturer to determine the conductivity as a function of
density.
A.2 Input data
The manufacturer shall have at least ten test results for thermal resistance and thermal conductivity, obtained
from external direct or from internal direct measurements in order to calculate the declared values. The direct
thermal resistance and thermal conductivity measurements shall be carried out at regular intervals spread
over a period of the last twelve months. If less than ten direct test results are available, that period may be
extended until ten test results are reached, but with a maximum period of three years, within which the product
and production conditions have not changed significantly.
For new products the ten thermal resistance or thermal conductivity test results shall be carried out spread
over a minimum period of ten days.
The declared thermal values and their corresponding densities shall be calculated according to one of the
methods given in A.3 at intervals not exceeding three months of production.

The minimum testing frequencies shall be understood as the minimum for each production unit/line under stable
manufacturing conditions. If for example the production per day is only 8 h, every day is a new start. In addition to the testing
frequencies given above, testing of the relevant properties of the product shall be repeated when changes or modifications are
made that are likely to affect the conformity of the product.
b
Under stable conditions (when the various parts of the assembly do not change in reaction to fire properties) no factory
production control is necessary

Frequencies are not given, as test methods are not yet available.

A minimum of 10 tests are needed statistically with a minimum of 4 from the PTD.

NOTE Not all Euroclasses may apply for the products conforming to this standard.
a
The minimum testing frequencies, expressed in test results, shall be understood as the minimum for a product or a product
group for each production unit/line under stable conditions. In addition to the testing frequencies given above, testing of relevant
properties of the product shall be repeated when changes or modifications are made that are likely to affect the conformity of the
product.
b
Direct testing may be conducted either by third party or by the manufacturer.
c
Indirect testing shall be either on the product or on its components.
d
Indirect testing is only possible in the case of products falling within the System 1 for attestation of conformity of reaction to
fire or by having a Notified Body verifying the direct testing.

Specimen preparation method for thermal resistance and thermal
conductivity test
C.1 Principle
The insulation product shall be placed or blown into a square rigid frame large enough to provide a test
specimen corresponding to the dimensions listed in Table 2.
C.2 Procedure
C.2.1 Specimen preparation method for masonry cavity walls and closed frame application
by placing beads into the frame.
C.2.1.1 General
The insulation product (bonded or unbonded) may be placed by hand into an insulating frame. The frame shall
be made of rigid insulating material, e.g. cellular plastic. The bottom of the frame shall be made of thin
material that will only give a negligible contribution to the total thermal resistance, e.g. perforated plastic foil
(13 ± 2) μm or perforated paper (75 ± 5) g/m . The foil may be
