5.3.1 Single lintels, combined lintels and composite lintels
5.3.1.1 General
The load bearing capacity shall be declared from the results of tests, using test methods specified in
this standard, or from their interpretation.
When calculation models are used to interpret and extend the results obtained from testing they
should be based on a mechanical approach and appropriate material properties. Historic test data
may be used to demonstrate the validity of the calculation model.
The ultimate demonstration of compliance with this standard shall be by testing, in accordance with
the methods in EN 846-9, on samples selected in accordance with Clause 8.
5.3.1.2 Load bearing capacity and load ratio
The requirements for flexural resistance in accordance with 5.3.1.3 and shear load resistance in
accordance with 5.3.1.5 shall be met in all cases.
NOTE The declared value of load bearing capacity is based on the lower of the flexural resistance
(see 5.3.1.3) and twice the shear load resistance (see 5.3.1.5).
The load bearing capacity in kN/m of the lintel shall be declared as a mean value. When required, the
characteristic value shall also be declared. Unless otherwise stated, these values shall be those
corresponding to the applicable maximum clear opening taking into account the declared values of
the minimum bearing length and the length of the lintel.
Where lintels are intended to support two or more leaves of masonry, any restrictions on the
distribution of load across the width of the lintel in terms of the range of load ratios that can be used
shall be declared.
5.3.1.3 Flexural resistance
When sampled in accordance with Clause 8 and tested by the method of EN 846-9, the flexural
resistance shall be greater than or equal to the declared value of load bearing capacity in accordance
with 5.3.1.2 and no individual value of flexural failure load shall be less than 90 % of the declared
value of load bearing capacity.
When it is required to declare a characteristic value in addition to declaring the vertical load capacity
according to EN 846-9 as a mean of the test results, the characteristic value should be taken as 0,9 of
the mean value.
5.3.1.4 Short term deflection
The short term vertical deflection, δ and also the horizontal deflection,δ , when relevant, at one
dv, dh
third of the declared load bearing capacity shall be declared. When sampled in accordance with
Clause 8 and tested in accordance with EN 846-9, for flexural resistance, the appropriate mean
deflections of the sample, as relevant, measured at one third of the declared load bearing capacity
shall be less than or equal to the declared deflections δ andδ .
dv dh
It is only necessary to declare the horizontal deflection δ if it is relevant.
dh
If it is required to know the long-term deflection, then the short term one may be increased according
to the loading regime, creep and shrinkage values given in the appropriate Eurocodes.
5.3.1.5 Shear resistance
When sampled in accordance with Clause 8 and tested by the method of EN 846-9, the shear
resistance shall be greater than or equal to 50 % of the declared value of load bearing capacity
evaluated in accordance with 5.3.1.2 and the shear failure load of any individual specimen shall be
not less than 45 % of the declared value of load bearing capacity.
When required, the shear resistance shall be declared additionally as a characteristic value.
When it is required to declare a characteristic value in addition to declaring the vertical load capacity
according to EN 846-9 as a mean of the test results, the characteristic value should be taken as 0,9 of
the mean value.
5.3.2 Prefabricated part of composite lintels
If the load bearing capacity of a composite lintel is not declared by the manufacturer, the following
parameters shall be declared for the prefabricated part:
 Geometry and configuration of the prefabricated part of the lintel including the position, diameter
and yield strength of the reinforcement.
 Characteristic tensile resistance, F , of the prefabricated part of the lintel in the ultimate limit
tkl
state. If relevant for durability, the tensile resistance shall also be given in the serviceability limit
state.
 Characteristic initial shear strength f between the prefabricated part of the lintel and the mortar
vk0i
in the bed joint above. The declaration may either be made on the basis of fixed values or tests.
The declaration shall indicate whether the initial shear strength has been obtained from fixed
values or from tests. When the declaration is based on fixed values the characteristic initial shear
strength may be declared by using the appropriate value of characteristic initial shear strength
given in Annex C of EN 998-2:2010. When the declared value is based on tests then the test
shall follow the procedure given in EN 846-14 and the initial shear strength of specimens when
sampled in accordance with Clause 8 and tested by the method given in EN 846-14 shall be
greater than or equal to the declared value.
5.4 Durability
5.4.1 General
The materials for the manufacture of the lintels and their corrosion protection systems shall be
selected in accordance with 5.4.2 or 5.4.3 and the material/coating reference in accordance with
Annex C shall be declared.
NOTE The durability of performance characteristics against corrosion is dependent on both the condition of
exposure of the masonry and the material/coating specification. This European Standard follows the state of the
art by giving material/coating specifications to suit.
5.4.2 Steel lintels
Steel lintels, other than those made from ferritic stainless steel, austenitic stainless steel or austenitic
ferritic stainless steel, shall be protected against corrosion in accordance with the requirements of C.1
in Annex C.
NOTE The corrosion protection required in any individual application will depend on the type of lintel,
whether a separate damp proof system is used, the degree of exposure and the climatic conditions and therefore
several grades of protection are given.
5.4.3 Concrete lintels and masonry lintels
The reinforcement of concrete and masonry lintels shall be protected against corrosion in accordance
with the requirements of C.2 and C.3 in Annex C.
The joints between the structural shell casing units and any grooves they contain shall be filled with
concrete or mortar. Where the joints are not filled, the units shall be considered to be non-structural.
5.5 Water penetration and installation
All necessary information on the correct procedure for installing the lintel to avoid the risk of water
penetration shall be provided.
NOTE For installation, see Annex B.
5.6 Thermal properties
Details shall be provided of the thermal properties of the materials from which the lintel is made by
reference to thermal conductivity values given in EN 1745, or, where not given in that standard, by
reference to thermal conductivity values given in European Standards for the materials of
construction.
5.7 Freeze/thaw resistance
5.7.1 General
When relevant to the uses for which the lintel is placed on the market and in all cases for lintels
intended to be used in external elements, the freeze/thaw resistance of lintels shall be declared.

Steel lintels may be classified as freeze/thaw resistant.
5.7.3 Concrete lintels
Lintels made with concrete conforming to EN 206-1 and meeting the requirements for exposure
class XF1 of EN 206-1:2000 may be classified as ‘freeze thaw/resistant’.
5.7.4 Masonry lintels
Masonry lintels may be classified as ‘freeze/thaw resistant’ where the following conditions are met:
a) the concrete part meets the requirements of 5.7.3 to be classified as freeze/thaw resistant; and
b) the masonry units in the lintel are freeze/thaw resistant according to the requirements of the
relevant part of EN 771.
5.8 Resistance to fire
Where relevant to the uses for which the lintel type is placed on the market, the resistance to fire shall
be classified on the basis of testing of a lintel, either as part of a wall with or without fire separating
function or as a beam, in accordance with EN 13501-2. Alternatively, the classification may be based
on tabulated values for the material type and form as given in the appropriate European Standards.
Where classification is relevant, a lintel type may be classified for use in particular forms of
construction, as verified from tabulated values or by the interpretation of test data.
All lintels can form part of a fire resisting construction when suitably protected. Where a lintel type is
intended for use in more than one form of construction, tests may need to be performed on one or
more test systems.
5.9 Water absorption
5.9.1 General
Where relevant to the uses for which the lintel is placed on the market and in all cases for concrete
and masonry lintels to be used in exposed external elements, the water absorption coefficient due to
capillary action or the initial rate of water absorption, as relevant, shall be declared.
5.9.2 Steel lintels
Steel lintels may be classified as having a water absorption coefficient of zero.
5.9.3 Other lintels
When lintels other than steel lintels are sampled in accordance with Clause 8 and tested by the
method of EN 772-11, for immersion times as specified in the relevant part of EN 771, the initial rate
of water absorption of clay masonry lintels and the coefficient of water absorption of other lintels shall
be not greater than the declared values.
5.10 Water vapour permeability
When relevant to the uses for which a lintel, other than a steel lintel, is placed on the market, the
water vapour diffusion coefficient (lower and upper values) in accordance with EN 1745 shall be
declared.
NOTE This characteristic is not relevant for steel lintels.
5.11 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 harmonised 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 Construction web site on EUROPA accessed through:
http://ec.europa.eu/enterprise/construction/cpd-ds/.
