performance without the need for testing, provided that they satisfy the definitions given in
Commission Decision 2000/553/EC [1], i.e. that:
— they satisfy the provisions of Commission Decision 96/603/EC [2], and
2
— any external coating shall be inorganic or have a gross calorific potential (PCS) ≤ 4,0 MJ/m or a
2
mass ≤ 200 g/m .
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
---------------------- Page: 11 ----------------------
SIST EN 490:2012+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 tested 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;
2
— for a coating system with a PCS > 2,0 MJ/kg and ≤ 4,0 MJ/m , 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 13501-
1.
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.

5.10 Release of dangerous substances
For products used within the European Economic Area, see Annex ZA, Note to ZA.1.
6 !Assessment and verification of constancy of performance (AVCP)"
6.1 General
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:
— !determination of the product type by" initial type testing (ITT), and
— 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 !, if they apply to
the product".
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.
