5.9.1.2 Test and assessment methods
5.9.1.2.1 Products satisfying the requirements for external fire performance, without the need for
testing
Tiles and fittings covered by this European Standard meet the requirements for external fire 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 mass
2
≤ 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);
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:
9
---------------------- Page: 11 ----------------------
SIST EN 490:2012
EN 490:2011 (E)
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 Evaluation of conformity
6.1 General
The compliance of a concrete roofing tile or fitting with the requirements of this European Standard shall be
demonstrated by:
initial type testing (ITT), and
10
---------------------- Page: 12 ----------------------
SIST EN 490:2012
EN 490:2011 (E)
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, 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).
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 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.
