Annex A
(normative)
Determination of declared thermal resistance and thermal
conductivity
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.
A.1 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 or indirect measurements In order to calculate the
declared value. The 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 obtained, but with a maximum period
of three years, within which the product and production conditions have not changed significantly. If
still less than ten direct test results are available, results from indirect tests can be used.
The mean thermal conductivity derived from thirty indirect measurements equals one direct
measurement (see note 2 under A.3). Each of the values derived from indirect measurements shall be
the mean value of mm. 30 individual λ-values derived from indirect test results. The tests for one final
λ-value may be performed over one month or over a longer period. No result must be used more than
once and no result must be excluded. The resulting ten results shall include at least three direct test
results.
For new products the ten thermal resistance and thermal conductivity test results shall be carried out
spread over a minimum period of ten days. The results shall include at least three direct test results.
The declared value shall be calculated according to the method given in A.3 and shall be recalculated
at intervals not exceeding three months of production.
A.2 Declared values
The derivation of the declared values R and λ from the calculated values R and λ shall use
D D 90/90 90/90
the rules given in 4.2.1, which include the rounding conditions.
A.2.1 Case where thermal resistance and thermal conductivity are declared
The declared value R and λ shall be derived from the calculated value, R and λ , which are

proportion between the minimum frequencies stated in Annex B).

Annex B
(normative)
Laboratory methods for the determination of settlement
B.1 Introduction
The purpose of the test methods described in this Annex is to determine the settling (long-term
change in thickness) of attic loose-fill thermal insulation and cavity applications by impact excitation,
vibration and acclimatization. They are accelerated laboratory methods and can be used for type
approval certificate testing. They can also be used for development of loose-fill thermal insulation
products.
The results of these tests give information of settling value for the loose fill product after a certain time
period under service conditions. The settling value is one property required for establishing design
thermal performance and for determining life time energy requirements.
The present accelerated test methods are based on the fact that the settling of attic loose-till thermal
insulation shall be determined under the same conditions as in real attic situation. It means that the
loose-fill materials are affected by the same main factors as in reality. It also means that the material
is tested as it is positioned in the real attic structure. Settling is accelerated by means of
 humidity changing more often than in reality,
 vibrations applied constantly,
 vibration shocks applied at regular intervals.
B.2 Principle
B.2.1 Settling of loose-fill insulation by impact excitation (method A)
An open-top box containing the loose-fill product is impacted to a rigid ground as a impact excitation.
The number of impacts and the height of drop is defined. The measured difference of the insulation
height before and after the impact excitation gives the settlement.
B.2.2 Settling of cavity insulation by vibration (method B)
A closed wooden box containing the cavity product is exposed to sinusoidal vibrations. The decrease
of the insulation height caused by the vibration is determined and the settlement calculated.
B.3 Apparatus
B.3.1 Apparatus for method A
B.3.1.1 General
The apparatus for method A shall consist elements indicated in B.3.1.2 to B.3.1.5.
prEN 15101-1:2005 (E)
B.3.1.2 Test box
The test box is an open top wooden box. It has a square cross section of 0,55 m 0,55 m. The height
of the box is 0,33 m.
B.3.1.3 Mass measuring equipment
For the determination of the mass use a scale with a dissolution of at least 50 g.
B.3.1.4 Insulation height measuring equipment
A measuring device comprising a tape measure and a square pressure plate. The tape measure shall
have an accuracy of at least 1 mm.
A pressure plate (200 ± 2) mm² which creates a total pressure on the test specimen of (20 ± 1,5) Pa.
Any test equipment, which provides the same results at least the same accuracy may be used.
B.3.1.5 Test equipment to produce the impact excitation
Stable steel-frame, on which a motor with a cam disk is assembled. A movable frame, which is led by
center bearings, so that it drops free of friction from the top point to the impact bed. The cam disk lifts
the movable frame by a ram stake to the top point. Behind the top point the movable frame drops
down to the impact beds. The drop height can be changed with adjusting-screws in the groundframe
with a top mounted rigid plastic bed. In order to automize the means, the motor should be controlled
by a counter. The test box is mounted on the movable frame. See Figure B.1.

The apparatus for method B shall consist of elements indicated in B.3.3.2 to B.3.3.5.
B.3.2.2 Test box
The test box is a pattern wall construction with a height of at least 1 m. The width of the pattern wall
shall be at least 0,625 m, the cavity depth should not less than 0,16 m. The frame of the construction
shall consist of at least 40 mm thick wood. On the side, there are any holes, closed by a punched
plate.
It is necessary to reduce the pressure inside the wall during installing the insulation. The top of the
frame should be a door to give the possibility to fill the insulation material by free-flowing.
The surface shall consist of minimum 16 mm thick multiplex sheets. Alternatively one surface can
consist of a 6 mm thick safety glass. In the wood surface, there is a blowing hole about 15 cm under
the top side in the middle of the surface. The diameter of the hole depends on the diameter of the
blowing tube. The front surface, for example the glass surface, should be a door to replace the
material after the tests and weight it.

For the determination of the mass use a scale with a dissolution of at least 50 g.
B.3.2.4 Insulation height measuring equipment
A measuring device comprising a tape measure and a square pressure plate. The tape measure
having a accuracy of at least 1 mm. A pressure plate (100 ± 2) mm², which experts a total pressure on
the test specimen of (50 ± 1,5) Pa . Any test equipment, which provides the same results at least the
same accuracy may be used.

B.4.3 Conditioning of test specimen
For preparing the test specimen taken from the sample of the material to be tested shall be stored for
a time specified by the relevant product standard but for at least 6 h at (23 ± 5) °C. In case of dispute
they shall be stored at (23 ± 2) °C and (50 ± 5) % relative humidity.

The test specimen shall be prepared as under working conditions. Either the material to be tested will
be filled into the boxes either manually or mechanically by special equipment. The surface of test
specimen will correspond with the surface of the test boxes.
When manually preparing the test specimen material should be carefully filled into the test box by
using a shovel. The quantity of the test material is selected in the way that the specimen is able to
achieve the required density.
When using a mechanical equipment, the test boxes should be filled using a tube of a diameter
similar to that used in working conditions. If its usual under working conditions to use a blowing nozzle,
the test specimen should also be prepared by means of a nozzle. The mechanical equipment shall be
adjusted in a way, so that the required density can be achieved in the test boxes.
