kerbs”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 1340:2003.
1 Scope
This European Standard specifies materials, properties, requirements and test methods for unreinforced, cement
bound precast concrete kerb units, channels and complementary fittings, that are for use in trafficked paved
areas and roof coverings.
The units are used to fulfil one or more of the following:
Separation, physical or visual delineation, the provision of drainage or the containment of paved areas or other
surfacing.
In case of regular use of studded tyres, additional requirements are sometimes needed.
This standard provides for the product marking and the evaluation of conformity of the product to this European
standard.
Apart from the tolerances, this standard does not include requirements for cross-sections, shapes and dimensions.
This standard does not deal with the tactility or visibility of kerbs.

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 .

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.

See Commission Decision 2000/553/EC.
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
Abrasion (only classes 3 and 4) Once per year per surface family
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.

6.3.7 Non-conforming products
If the results of the tests on a product are unsatisfactory, the manufacturer shall take the necessary steps in order
to rectify the shortcoming.
Products which do not conform to the requirements shall be set aside and marked accordingly.
If any non-conformity of the product is established after delivery, the customer shall be notified.
6.3.8 Product conformity criteria
For each characteristic, when the conformity criteria in this clause may be considered either by attributes or
variables, the method applied shall be at the manufacturer's discretion.
6.3.8.1 Shape and dimensions
A. Attributes
The conformity of the production with 5.2 shall be assessed for each production line per one to four production
days (see sampling according to A.4.1.3). Each of the requirements in 5.2 shall be considered separately.
a) If the sample consists of less than eight kerbs (see switching rules in A.5) and each of the requirements in
5.2 are complied with by all of the kerbs, then the sample and the corresponding production shall be
accepted. If not, this sample shall be increased to eight kerbs and the procedure given in b) shall apply.
b) If the sample consists of eight kerbs and not more than one of the kerbs does not conform to any one of
the requirements in 5.2 considered separately, the sample and the corresponding production shall be
accepted. If not, this sample shall be increased to 16 units and the procedure given in c) shall be applied.
c) If the sample consists of 16 kerbs and not more than two of the kerbs do not conform to any one of the
requirements in 5.2 considered separately, the sample and the corresponding production shall be
accepted. If more than two of the kerbs do not conform to any one of the requirements considered
separately, the sample and the corresponding production are not accepted and 6.3.7 applies.
B. Variables
When the standard deviation of a production line is known and regularly checked, the compliance of the
production with 5.2 shall be assessed for each production line per day or consecutive production days not
exceeding five (see sampling according to A.4.1.3). Each of the requirements in 5.2 shall be considered
separately.
The conformity is assessed on a 10 % fractile.
The acceptability of the samples considered shall be checked using a control chart conforming to either with
ISO 7966 or ISO 7873 and taking into account 5.2, provided the probability of acceptance is equivalent to that
resulting from assessment by attributes.
6.3.8.2 Weathering resistance (class 2 - water absorption)
The conformity of the production with 5.3.2 (class 2) shall be assessed for each family and for each five
production days, or more according to the switching rules (see sampling according to A.4.1.6)
If the sample consists of three or six kerbs (see switching rules in A.5) and the requirements in 5.3.2 (class 2)
are complied with, the sample and the corresponding production shall be accepted.
6.3.8.3 Bending strength
A. Attributes
The conformity of the production with 5.3.3 shall be assessed for each production line per one to four production
days (see sampling according to A.4.1.4).
a. If the sample consists of eight kerbs or fewer (see switching rules A.5) and the strength T of each of the kerbs
is not lower than the characteristic value of Table 3 for the declared class, the sample and the corresponding
production shall be accepted. If not, this sample shall be increased to 16 kerbs and the procedure given in b)
shall apply.
b. If the sample consists of 16 kerbs and the strength T of not more than one of the kerbs is lower than the
characteristic value of Table 3 for the declared class, the sample and the corresponding production shall be
accepted. If not, the sample and the corresponding production are not accepted and 6.3.7 applies.
B. Variables
When the standard deviation for a production line is known and regularly checked, the conformity of the
production with 5.3.3 shall be assessed for each production line per production day or consecutive production
days not exceeding five (see sampling according to A.4.1.4).
The compliance is assessed on a 5 % fractile.
The acceptability of the samples considered shall be checked using a control chart conforming either to ISO 7966
or to ISO 7873 and taking into account 5.3.3, provided the probability of acceptance is equivalent to that resulting
from assessment by attributes (see annex K).
If the sample and the corresponding production are not accepted, 6.3.7 applies.
6.3.8.4 Visual aspects
The conformity of the production with 5.4 shall be assessed in case of doubt (see sampling according to A.4.1.2).
The sample tested shall satisfy the requirements of the standard. If not, the sample and the corresponding
production are not accepted and 6.3.7 applies.

A.5 Switching rules
A.5.1 Normal inspection
The rate of sampling should be in accordance with A.4.1.
A.5.2 Normal to reduced inspection
1)
Reduced inspection corresponds to half the rate of normal inspection . It should be used where normal
inspection is effective and the preceding 10 successive samples have been accepted.
A supplementary reduced inspection is allowed if the same conditions as above are satisfied under
reduced inspection. This supplementary reduced inspection should correspond to half the rate of the
reduced inspection.
A.5.3 Reduced to normal inspection
When reduced inspection or supplementary reduced inspection is in effect, normal inspection should be
reinstated if any of the following occurs:
- a sample is not accepted;
- or the production becomes irregular or delayed;
- or other conditions warrant that normal inspection should be instituted.
A.5.4 Tightened inspection
Tightened inspection requires the number of kerbs in the sample to be doubled.
It should be used if during normal inspection two out of five
