5.3.1 General
The kerbs shall conform to the following requirements at the time they are declared suitable for use by the
manufacturer.
When complementary fittings or kerbs, because of their geometry, cannot be tested according to this standard,
they are considered to conform to this standard, provided they have at least the same concrete quality as kerbs
conforming to this standard.
5.3.2 Weathering resistance
5.3.2.1 Test methods
The weathering resistance is determined by tests according to annex D for freeze-thaw resistance or annex E
for water absorption and to the conformity criteria of 6.3.8.2.
5.3.2.2 Performances and classes
The kerbs shall conform to the requirements in Tables 2.1 or 2.2.

Slip /skid resistance is determined by testing in accordance with the test method as described in ENV 12633
NB If ENV 12633 is published separately as a CEN TS, the reference will need to be changed editorially
before final publication
5.3.5.2 Performance and classes
Requirements for slip/skid resistance are given in Table 5.3. Both the unpolished and polished values shall,
satisfy the requirements for the class

1 P No performance measured
2 Q > 35
3 R > 45
4 S > 55
Note 1 If the surface of a kerb contains ridges, grooves or other surface features which prevent testing by the pendulum
friction equipment, the product is deemed to satisfy the requirements of this standard without testing. Where the kerb is
too small to provide a test area, the manufacturer shall test a larger kerb having the same surface finish as the kerb in
question.
NOTE 2 The slip/skid resistance value relates to kerbs as manufactured and helps to ensure adequate slip/skid
resistance on installation.
5.3.5.3 Durability of slip/skid resistance
Under normal conditions of use precast concrete kerbs provide satisfactory slip/skid resistance during the
working life of the product, provided they are subjected to normal maintenance and unless a major proportion
of aggregates which polish excessively have been exposed on the upper face.
NOTE The development of a performance based test method for the durability of slip/skid resistance is proceeding in
TC 178 WG4.
5.3.6 Fire performance
5.3.6.1 Reaction to fire
1)
Concrete kerb units are Class A1 reaction to fire without testing .

without the need for testing .
5.3.7 Thermal conductivity
If concrete kerbs are intended to contribute to the thermal performance of an element, then the manufacturer
shall declare the thermal conductivity using design data from EN 13369.
5.4 Visual aspects
5.4.1 Appearance
The face of the kerb shall not exhibit defects such as cracking or flaking when examined in accordance
with annex J.
In the case of two-layer kerbs examined in accordance with annex J, there shall be no delamination
(i.e. separation) between the layers.
NOTE When efflorescence occurs it is not deleterious to the performance of the kerbs in use and is not considered
significant.
5.4.2 Texture
In the case of kerbs manufactured with a special surface texture, this texture shall be described by the
manufacturer.
If examined in accordance with annex J, compliance shall be established if there are no significant differences in
texture to any samples supplied by the manufacturer and approved by the purchaser.
NOTE Variations in the texture consistency of the kerbs can be caused by unavoidable variations in the properties of
the raw materials and by variations in curing and are not considered significant.
5.4.3 Colour
Colours may be provided in a facing layer or throughout the unit at the manufacturer's discretion.
If examined in accordance with annex J, compliance shall be established if there are no significant differences in
colour to any samples supplied by the manufacturer and approved by the purchaser.
NOTE Variations in the colour consistency of the kerbs can be caused by unavoidable variations in the shade and
properties of the raw materials and by variations in hardening and are not considered significant.

6 Evaluation of conformity criteria
6.1 General
For the purpose of testing, the manufacturer may group products into families, where it is considered that the
value of a selected property is common to all products within that family. Such families are:
1) strength family: kerbs manufactured using the same mix design and production methods, irrespective
of dimensions and colours;
2) surface family: kerbs with face mixes having the same main aggregate used in the mix (e.g. natural
river gravel, crushed granite, porphyr, basalt or limestone) and the same surface treatment of the
finished product, irrespective of dimensions and pigmentation.
6.1.1 Demonstration of conformity
Compliance of the product with the requirements of this standard and with the declared values (levels or
classes) for the product properties shall be demonstrated by carrying out both:
type testing of the product (see 6.2);
factory production control (see 6.3), including product testing.
6.1.2 Assessment of conformity
In addition, compliance of the product with this standard may be assessed:
either by a third party inspecting the manufacturer’s type testing and factory production control
procedures;
or by acceptance testing of a consignment at delivery (e.g. in the case of dispute, see annex B).
6.2 Type testing of the product
6.2.1 Initial type testing
Initial type testing shall be performed to demonstrate conformity with this standard at the beginning of the
manufacture of a new product type or a family of product types or setting up a new production line to confirm that
the achieved properties of the product meet the requirements of this standard and the values declared for it by the
manufacturer.
6.2.2 Further type testing
Whenever a change occurs in the raw materials, the proportions used or the production equipment or process,
which would change significantly some or all of the properties of the finished product, the type tests shall be
repeated for the selected property or properties.
NOTE Examples of major changes:
1) change from natural river gravel to crushed rock aggregates or change of cement type or class;
2) partial substitution of cement by additions.
For abrasion and weathering resistance, type testing shall be repeated periodically with the frequency given in
Table 5 even when no change occurs.

Table 5 — Periodically repeated type testing
Property Frequency

1)
Weathering resistance (only class 3) Once per year per surface family
1)
If for a surface family the result of a type test (mass loss) is lower than 50 % of the required value
the test frequency may be reduced to once per two years.
If for a surface family, routine water absorption testing at the frequency for class 2 products
(see 6.3.8.2.) is carried out to demonstrate consistency with kerbs submitted to freeze/thaw testing,
the required test frequency may be reduced to once per two years.
6.2.3 Sampling, testing and compliance criteria
The number of kerbs to be tested shall be in accordance with Table 6 for the selected property.
