declared according to the provisions of 5.9.1.2.
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

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

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);
---------------------- 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;

— 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-

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
