— any external coating shall be inorganic or have a gross calorific potential (PCS) ≤ 4,0 MJ/m 2 or a
mass ≤ 200 g/m 2 .

For this purpose the calorific value or mass of the organic coating shall be measured over the exposed
area only.
NOTE
Member States may have national ‘deemed to satisfy’ lists, which include more products than those
given in Decision 2000/553/EC.

5.9.1.2.2 Other products
Products not meeting the provisions of 5.9.1.2.1 shall be tested and classified in accordance with
EN 13501-5 using the classification(s) relevant for the country of destination of the products. The
products to be tested shall be installed, in addition to the general provisions given in ENV 1187, in a
manner representative of their intended use.

5.9.2 Reaction to fire performance
5.9.2.1 Requirements
This characteristic shall be declared when subject to regulatory requirements, and may be declared
when not subject to such regulatory requirements. The reaction of products to fire shall be determined
and declared according to the provisions of 5.9.2.2.
This characteristic does not apply to glued tiles or fittings. For such products, no indication needs to be
given related to their reaction to fire performance, nor does Class F need to be given.

5.9.2.2 Testing and assessment methods
5.9.2.2.1 Products satisfying the requirements for the fire reaction Class A1, without the need for
testing
Tiles and fittings are classified Class A1 of the characteristic reaction to fire, in accordance with the
provisions of Commission Decision 96/603/EC [2] , as amended, without the need for testing, provided
that:
— they contain ≤ 1,0 % by weight or volume (whichever is the lower) of homogeneously distributed
organic material (other than glue);

9



BS EN 490:2011+A1:2017

EN 490:2011+A1:2017 (E)

— any coating system (i.e. organic layer and cement slurry layer, if relevant), which contains ≤ 1,0 %
by weight or volume (whichever is the lower) of homogeneously distributed organic material, is
itself Class A1.

5.9.2.2.2 Other products
Products not meeting the requirements of 5.9.2.2.1 shall be tested and classified in accordance with
EN 13501-1 as follows:
— for a coating system with a gross calorific potential (PCS) ≤ 2,0 MJ/kg, when te sted according to
EN ISO 1716, the product may be classified A1;
— for a coating system with a PCS ≤ 2,0 MJ/m², the product may be classified A1 provided that the
coating system, when tested according to EN 13823, meets the requirements for this given in
EN 13501-1;
— for a coating system with a PCS > 2,0 MJ/kg and ≤ 4,0 MJ/m 2 , when tested according to EN
ISO 1716, the complete coating system shall be tested according to EN 13823, and mounted on
either the calcium silicate or fibre cement substrates given in EN 13238. If the coating system meets
the requirements of Class A2, the product shall also be classified Class A2 with appropriate smoke
and droplets sub-classification;
— for any coating system other than those stated above, the coating shall be tested for the
requirements of classes lower than A2 and the product shall be given the same class as the coating
system;
— as an alternative to the above requirements, the coated product itself shall be tested and the
classification requirements of EN 13501-1 shall apply. For tests to EN 13823, the product shall be
mounted and fixed in a manner which is representative of its intended application (i.e. mounted on
timber battens with no underlying insulation or organic material) in accordance with EN 491.

The requirements above relate to uncoated tiles or fittings which are Class A1. Where the uncoated tiles
or fittings contain > 1,0 % by weight or volume (whichever is the lower) of homogeneously distributed
organic material and are not Class A1, coated products shall be classified in accordance with EN 135011.
Results obtained for a coating system including an organic layer, apply to any other coating systems
containing the same composition as the system tested (e.g. the same generic type of polymeric binding)
but having less organic material and, therefore, a PCS which is less than that tested.
The classification obtained from tests of any tile profile or design also applies to tiles of the same body
material and the same composition of organic coating, for:
— any other tile design (i.e. any other tile profile and single lap or double lap tiles), and fittings;
— tiles with a different surface texture (i.e. smooth, patterned or granulated);
— tiles laid with headlap greater than that tested;
— tiles laid in straight or broken bond
— tiles laid with or without mechanical fixings;
— tiles laid on other timber or metal battens, with or without counterbattens;
— tiles used for pitched roofs, wall cladding or wall lining; laid with any or no thermal insulation.

! Assessment and verification of constancy of performance (AVCP) "


6.1 General

! "
— ! determination of the product type by" initial type testing (ITT), and

The compliance of a concrete roofing tile or fitting with the requirements of this European Standard
and with the performances declared by the manufacturer in the declaration of performance
(DoP)
shall be demonstrated by:
— factory production control (FPC).
For the purpose of testing, tiles and/or fittings may be grouped into families when it is considered that a
given characteristic or characteristics is/are common to all tiles and/or fittings within a family.

6.2 Type testing
Initial type testing shall be performed to demonstrate conformity to this European Standard. All
characteristics given in Table 2 shall, where relevant, be subject to initial type testing.
Tests previously performed to demonstrate conformity to the provisions of this European Standard
(same product, same characteristic(s), same sampling regime, same system of attestation of conformity)
may be taken into account.

!

"

In respect of reaction to fire performance, if the raw materials for coating systems are supplied with a
declaration of their PCS values
demonstrating their compliance , no testing for PCS is required to
demonstrate compliance with the limits given in 5.9.2.2.2.
Whenever a change occurs in the product design or raw material, or the production process, which
would change significantly one or more of the stated characteristics, the type test shall be repeated for

the appropriate characteristic(s).

!

A manufacturer may use the results of the product type determination obtained by someone else
(e.g. by another manufacturer, as a common service to manufacturers, or by a product developer), to
justify his own declaration of performance regarding a product that is manufactured according to the
same design (e.g. dimensions) and with raw materials, constituents and manufacturing methods of the
same kind.

"

6.3 Factory production control (FPC)
The manufacturer shall establish, document and maintain an FPC system to ensure that the products
placed on the market conform to the requirements of this European Standard. The FPC system shall
consist of procedures, regular inspections and tests and/or assessments, to control raw or other
materials or components, equipment, the production process and the product. The FPC system shall be
sufficiently detailed to ensure that the conformity of the product is apparent.

"

The FPC system shall include the tests identified in the relevant column in Table 2
the product .

! , if they apply to

The results of inspections, tests, or assessment requiring action and any action taken, shall be recorded.
The action to be taken when control values or criteria are not met shall be recorded.
An FPC system conforming to the requirements of EN ISO 9001, and made specific to the requirements
of this European Standard, is considered to satisfy the requirements for FPC.

7 Sampling
7.1 Sampling for type tests
Tiles and fittings for type tests shall be sampled in accordance with the sampling plan given in Table 2
and the sampling procedure given in Annex D.
A "day of production" is defined as any period within one 24 h day (or period) of production of roofing
tiles or fittings.

7.2 Sampling for FPC
Tiles and fittings for FPC shall either be sampled in accordance with the sampling plan given in Table 2
or sample sizes and frequencies shall be determined by the use of statistical process control methods
and/or acceptance sampling such that not less than 95 % of products satisfy the requirements of each
production control test.

7.3 Compliance
When evaluating products in accordance with this European Standard each test shall be considered
separately.
If one tile or fitting does not meet the requirements then a second sample of 10 tiles or fittings (11 tiles
for cover width) shall be taken. All of the tiles and or fittings in the second sample shall meet the
requirements. If more than one tile or fitting in the first sample fails or if one tile or fitting in the second
sample fails then the products being evaluated shall be deemed not to satisfy the requirements of this
European Standard.

Annex A

(informative)

Surface characteristics
The exposed surface of the tiles and fittings should have a structure that gives a harmonious
appearance to the finished roof or wall. However, slight colour variations may occur as a consequence
of the production process.
The following surface characteristics are permissible:
— superficial, non-continuous cracks on the unexposed surfaces of the tile or fitting which are the
result of the method of production;
— scratches and abrasions caused by packing, loading and transport; providing they do not prejudice
the other quality requirements.
Under the influence of natural weathering, changes in colour and appearance may occur.
The tiles and fittings may show slight efflorescence; it does not change the other quality requirements.

Annex B

(informative)

Performance of assemblies of roofing tiles and fittings
The performance of a roof or external or internal wall cladding, covered with roofing tiles and fittings,
depends not only on the properties of the products as required by this European Standard but also on
the design and construction of the roof or wall as a whole in relation to the environment and conditions
of use.

Annex C

(normative)

Fasteners and fixings
Tiles and fittings, which meet the requirements of this European Standard, shall be capable of being
fixed to the roof or wall structure, or another component, by mechanical fasteners and fixings.
Typically these mechanical fasteners and fixings may be, e.g. nails, screws, hooks, clips, wires.
These mechanical fasteners and fixings shall not adversely affect the function or the performance of the

concrete roofing tiles or fittings in use.
NOTE
Test methods for the evaluation of the strength of fasteners and fixings are given in EN 14437 [3] and
CEN/TS 15087 [4] .

Annex D
(normative)
Sampling procedure

D.1 General
Sampling shall be conducted in accordance with either: D.2, D.3 or D.4. The sampling procedure shall be
such that every tile or fitting has an equal chance of being selected for the sample.

D.2 Sampling from the roof or wall or unpacked consignment
Select the appropriate number of tiles or fittings (see Table 2) at random from positions throughout the
roof or wall or unpacked consignment without any consideration being given to the condition or quality
of the selected tiles or fittings.

D.3 Sampling from stacks or packs
D.3.1 General
When sampling in accordance with D.2 is impractical or not convenient, e.g. when the tiles or fittings
come from a large stack or a stack with ready access to only a limited number, one of the procedures
described in D.3.2 or D.3.3, as appropriate, shall be used.


D.3.2 Sampling from a stack
Divide the stack of tiles or fittings into sections of similar size. Select an equal number from different
parts of each section in order to give the required number of samples without any consideration being
given to the condition or quality of the selected product.
NOTE
It may be necessary to remove some sections of the stack in order to gain access to the products within
the body of the stack, but movement of products should be kept to a minimum.

D.3.3 Sampling from a consignment formed of banded or wrapped packs
Select packs of tiles or fittings from different parts of the consignment, and select an equal number from
different parts of each of the packs in order to give the required number of samples (see Table 2),
without any consideration being given to the condition or quality of the selected product.

D.4 Sampling for FPC
Sampling for FPC shall be representative of the tiles and/or fittings produced.
Dividing the sample: When the sample is to provide tiles or fittings for more than one test, the total
number shall be collected together and then divided by taking products from different parts of the total
sample.

Annex ZA

(informative)
Clauses of this European Standard addressing the provisions of the EU
Construction Products Regulation

ZA.1 Scope and relevant clauses
This European Standard has been prepared under the following mandates given to CEN by the
European Commission and the European Free Trade Association:
— M/121, ‘Internal and external wall and ceiling finishes’, and
— M/122, ‘Roof coverings, roof lights, roof windows and ancillary products’.
If this European standard is cited in the Official Journal of the European Union (OJEU), the clauses of
this standard, shown in this annex, are considered to meet the provisions of the relevant mandate,
under the Regulation (EU) No. 305/2011.
This annex deals with the CE marking of the concrete roofing tiles and fittings for roof covering and wall
cladding intended for the uses indicated in Table ZA.1.1 to Table ZA.1.2 and shows the relevant clauses
applicable.
NOTE 1
In addition to any specific Clauses relating to dangerous substances contained in this European
Standard, there may be other requirements applicable to the products falling within its scope (e.g. transposed
European legislation and national laws, regulations and administrative provisions). In order to meet the
provisions of the EU Construction Products Regulation, these requirements also need to be complied with, when
and where they apply.
NOTE 2
National regulations on dangerous substances may require verification and declaration on release, and
sometimes content, when construction products covered by this European 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. An informative database of European and national
provisions on dangerous substances is available at the Construction web site on EUROPA (accessed through
