4 Product characteristics
4.1 General
Product characteristics shall be assessed in accordance with Clause 5. To conform with this document,
products shall meet the requirements of 4.2, and the requirements of 4.3 as appropriate.
This document gives requirements for two different groups of applications:
— roof, ceiling and floor insulation;
— insulation in ground floors.
The main difference between the two applications lies in the requirement for water suction height in
ground floors, whereas there should be no requirement for water suction height when the products are
used for roof, ceiling and floor insulation.
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.
The thermal values shall be determined in accordance with Annex A and declared, according to the
following:
oSIST prEN 14063-1:2016
prEN 14063-1:2016 (E)
— the reference mean temperature shall be 10 °C;
— the measured values shall be expressed with three significant figures;
— the declared thermal values, shall be given as limit values representing at least 90 % of the
production determined with a confidence level of 90 %;
— the declared thermal resistance, R , shall be calculated from the insulation thickness and the
D
declared thermal conductivity, λ (see NOTE 1);
D
— the value of thermal conductivity λ shall be rounded upwards to the nearest 0,001 W/(m·K)
90/90
and declared as λ in levels with steps of 0,001 W/(m·K);
D
— 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.
NOTE 1 The declaration of the installed thermal resistance for loose fill expanded clay LWA is described in
EN 14063–2.
NOTE 2 A correlation between thermal conductivity and loose bulk density / particle size distribution, specific
to the production and each product, can be used for indirect testing (see A.4).
4.2.2 Loose bulk density
Loose bulk density shall be measured in accordance with EN 1097-3 and declared in classes with steps
3 3 3 3
(0,005 Mg/m ) up to a density of 400 kg/m (0,400 Mg/m ) and thereafter with steps of
of 5 kg/m
3 3
10 kg/m (0,010 Mg/m ) and shall be in the range of ±15 % of the declared value. The value shall be
3 3
expressed in kg/m (Mg/m ).
NOTE The dry loose bulk density for expanded clay LWA products will normally be in the range
3 3 3 3
150 kg/m (0,150 Mg/m ) to 800 kg/m (0,800 Mg/m ).
4.2.3 Aggregate size
4.2.3.1 General
Aggregate sizes shall be determined using a pair of sieve sizes selected from the basic sets specified in
Table 1 of EN 13055:2016 and the upper and lower sizes declared as product designation.
NOTE 1 The declaration accepts the presence of some particles, which will be retained on the upper sieve
(referred to as (D)) and some, which will pass the lower sieve (referred to as (d)).
NOTE 2 Normally the aggregate size for expanded clay LWA products will be in the range 0 mm to 32 mm.
4.2.3.2 Undersize
The quantity of the undersize passing the lower sieve (d) shall not exceed 15 % by mass.
4.2.3.3 Oversize
The quantity of the oversize retained on the upper sieve (D) shall not exceed 10 % by mass. When
required, the sieve through which 100 % of the aggregate passes shall be declared.
4.2.3.4 Grading
When required, the particle size distribution shall be determined in accordance with EN 933-1 without
washing and a grading declared.
oSIST prEN 14063-1:2016
prEN 14063-1:2016 (E)
4.2.4 Reaction to fire
Reaction to fire classification (Euroclass) shall be determined in accordance with EN 13501-1.
NOTE Expanded clay LWA as described in 3.1.1 is classified without testing as a class A1 product in
accordance with Commission Decision 96/603/EC as amended by Commission Decision 2000/605/EC.
4.2.5 Durability characteristics
4.2.5.1 General
The appropriate durability characteristics have been considered and are covered in 4.2.5.2, 4.2.5.3 and
4.2.5.4.
4.2.5.2 Durability of reaction to fire against ageing/degradation
The reaction to fire performance of expanded clay does not change with time. The product is classified
without testing as a class A1 product in accordance with EN 13501-1.
4.2.5.3 Durability of thermal resistance against ageing/degradation
The thermal conductivity (4.2.1) of the product does not change with time and neither does the
insulation thickness since any settlement (4.3.5) is negligible.
4.2.5.4 Durability of compressive strength against ageing/degradation
The compressive strength of expanded clay does not change with time. The product is a clay mineral
product burnt to clinkers in a stable structure.
4.3 For specific applications
4.3.1 General
If there is no requirement for a characteristic, described in 4.3, for a product in use, then the
characteristic need not be determined and declared.
4.3.2 Specific heat capacity
When required, the specific heat capacity shall be determined in accordance with EN ISO 10456.
NOTE In accordance with EN ISO 10456, a typical value for specific heat capacity of 1 000 J/(kg K) can be
used.
4.3.3 Crushing resistance
When required, the bulk crushing resistance shall be determined in accordance with EN 13055:2016,
2 2 2
Annex C, shall be expressed in N/mm and declared in levels with steps of 0,05 N/mm up to 1,0 N/mm
and thereafter with steps of 0,1 N/mm .
4.3.4 Compressibility and confined compressive strength
When required, the compressibility and the compressive strength CS(10) shall be determined in
accordance with EN 1097-11 and values declared. A stiffness modulus shall be given as the tangent to
the stress-strain relationship curve and related to the level of deformation.
NOTE The compressive strength at 10 % strain is not a design value, it is used as a reference value for
material characterization only. For characterization of material properties the stiffness modulus and the load at a
strain level at maximum 2 % (CS(2)) is more relevant.
oSIST prEN 14063-1:2016
prEN 14063-1:2016 (E)
4.3.5 Settlement
Settlement for expanded clay LWA is negligible and needs no measurement.
4.3.6 Water vapour transmission
When required, the water vapour transmission shall be declared. The characteristic is not measured
because the open structure of the final product itself offers no substantial resistance to the free
movement of water vapour.
NOTE According to EN ISO 10456, a typical water vapour resistance factor μ is 2.
4.3.7 Water suction height
When required, water suction height shall be determined in accordance with EN 1097-10, and declared,
expressed in mm.
NOTE Declaration of water suction height is only relevant for applications in contact with the ground.
4.3.8 Dangerous substances
National regulations on dangerous substances may require verification and declaration on release, and
sometimes content, when construction products covered by this standard are placed on those markets.
In the absence of European harmonized test methods, verification and declaration on release/content
should be done taking into account national provisions in the place of use.
NOTE An informative database covering European and national provisions on dangerous substances is
available at the Growth website on EUROPA accessed through:
