CEN/TS 15447:2006 (E)
Introduction
The Essential Requirements of the CPD apply to the construction works. Interpretative documents
have been produced to form a link between the Essential Requirements and the performance
characteristics of construction products incorporated in a permanent manner in construction works, i.e.
1
in end-use application . The Essential Requirement concerned in this document is “Safety in case of
fire”, and from that requirement the reaction to fire performance of construction products only is
considered.
Technical specifications under the CPD, such as product standards, deal with construction products
and their reaction to fire performance. For the assessment of reaction to fire performance the
technical specifications use a set of supporting fire standards through reference to the classification
standard EN 13501-1.
Five reaction to fire test methods have been developed for the purpose of testing construction
products, including products incorporated within building elements. The procedure for classification is
outlined in EN 13501-1 providing a choice of Euroclasses. Since EN ISO 1182 (“non-combustibility”)
and EN ISO 1716 (“gross calorific potential”) deal with material characteristics and are thus
2
independent of the end-use application of the product, the mounting and fixing instructions presented
apply to EN 13823, EN ISO 9239-1 and EN ISO 11925-2.
Technical specifications refer to EN 13501-1 for the assessment of reaction to fire performance. The
EN 13501-1 refers to the five supporting test standards for determination of the relevant parameters.
In principle a product standard should not refer directly to the test standards. However, where
EN 13501-1 and the test standards do not fully define the mounting and fixing of a product in a test,
the relevant product standard may add instructions to ensure that the test result is representative of
the product behaviour in one or more end-use applications when exposed to a fire in the relevant fire
scenario.
In the absence of standard mounting and fixing rules, a test result is only valid for the end-use
application that is represented by the mounting and fixing (and other test configuration aspects) used
3
in the test . As a consequence all other end-use applications have to be tested. EN 13501-1, test
standards and substrate standard EN 13238 contain some aspects of standardised mounting and
fixing, to some degree limiting the number of tests to be performed to classify a product, which can
lead to CE-marking. To limit the number of tests further, standardised mounting and fixing test
arrangements may be introduced in the technical specifications. This may reduce the number of m&f
test arrangements needed to cover all possible end-use applications to a few or even one.
A reaction to fire test method may in principle be used to assess the performance of (a) a material; (b)
a product (a combination of one or more materials) without taking into account the incorporation of the
product in the building; or (c) a product in its end-use application (i.e. taking into account the
incorporation of the product in the building).
This frame work should be used by technical specification writers to develop further specific rules for
product groups.

1
In some documents “end-use application” is used as a global indication of the use of the product (e.g. use as
wall lining or ceiling lining). The more detailed description of the way the product is incorporated in the building in
the (global) “end-use application” is then referred to as “end-use condition” (including e.g. jointing, fixing and
position in relation to adjacent products).
In this document the two terms are both covered by “end-use application”, in line with the definition given in EN
13501-1.
2
In this document “mounting and fixing” is often abbreviated as “m&f”.
3
When direct field of application rules are defined it should read “only valid for the direct field of application of
the test results”.

4 General approach
4.1 Mounting and fixing of products in tests representing the end-use applications
The basic concept of the Construction Products Directive (CPD) is that construction products are
tested in relation to their end-use application. The mounting and fixing (m&f) instructions are devoted
to that.
The product, as put on the market, shall be submitted to the tests for the purpose of CE marking and
hence classification. The mounting and fixing options apply and define the field of application of the
classification. Generic products shall be tested and classified in a consistent manner throughout
Europe.
Two options for mounting and fixing are available:
 standardised mounting & fixing to cover a group or possibly all end-use applications;
 mounting & fixing representative of a specific end-use application.
Standardized m&f arrangement should be defined in a technical specification, respecting the general
rules laid down in the supporting fire standards, to enlarge the field of application of a test result. For
all standardized m&f arrangement specifications its field of application shall be defined, using the
principle that the performance in the standardized m&f is equal to or lower than the performance in
the end-use applications covered.
Without standardised mounting and fixing test arrangements all end-use applications should be tested.
Using standardized m&f test arrangements this can be limited to a few or even one end-use
4
application .
In the tests, the product shall be tested so that, as far as possible, the classification relates to its
performance in end-use application. Composite products are tested as such. However, if underlying
layers can be exposed in the end-use application, the ignitability test shall be applied on the edge of
the specimens so as to assess the ignitability of the underlying layers.
For products that are covered by another surface product in the end-use application, the thermal
attack in the testing should be on the surface product of the assembly of products which is tested.
Where the end-use application is known the product may be tested accordingly or using standardised
m&f arrangement. Products may be tested using a specific m&f test arrangement advised by the

4
In the case that a direct field of application of the test result is defined the number may already be limited.
8

---------------------- Page: 9 ----------------------

CEN/TS 15447:2006 (E)
producer; the applicability of the resulting classification is likely to be limited (to the end-use
application(s) represented by the chosen m&f test arrangement).
Tests performed on “sliced” products (products with top layers removed) for reaction to fire
information about the different layers, are not to be used for CE marking purposes.
4.2 Classification not representative of performance in end-use application
Some Member States require, for regulatory purposes, the classification for the product in isolation
(not taking into account the incorporation of the product in the building, i.e. the end-use application).
Accordingly Technical Committees may, if appropriate, devise simple standardised mounting and
fixing arrangements for these tests.
4.3 Other ways of classifications
Where proof is provided that test results are not representative of the fire behaviour in one or more
end-use applications, alternative m&f instructions for the currently used supporting fire tests,
alternative fire tests, or even alternative reference scenario(s) and related test(s) (whether small,
intermediate or large scale) may be used to assess the performance of the building products under
consideration. The only procedure to call upon this alternative route for classification is outlined in
Guidance document “G”, Clause 4. This procedure is open to “Member States (e.g. fire regulators),
CEN/ CENELEC/ EOTA, European Industry Federations or the Fire Sector Group of Notified Bodies”
[GP G], not for individual manufacturers.
NOTE None of the reaction to fire tests for classification are suitable for assessing directly full scale
assemblies. For that purpose large-scale tests should be used. These large-scale tests are primarily meant for
risk-oriented assessment. This procedure is not to be used for CE-marking purposes unless it is the result of the
procedure outlined in Guidance document “G”.
4.4 Product parameters and end-use application parameters
Standardized mounting and fixing instructions are based on the principle that the performance in such
a m&f arrangement is equal or lower compared to that in the end-use applications covered.
To be able to make this comparison, the following product and end-use application parameters, and
their variability, should be taken into account:
 thickness;
 density;
 colour;
 surface coating;
 composition of product;
 geometry and structure, e.g. shape, number and composition of layers;
 substrate;
 method of fixing;
 joints, type and position;
 air gaps;
9

---------------------- Page: 10 ----------------------

CEN/TS 15447:2006 (E)
 edges;
 product orientation;
 exposure to thermal attack.
The parameters of this list that may be part of the m&f instructions are discussed in this document.
Parameters may be neglected if it is demonstrated that they have no effect on the reaction to fire
performance or if they are not relevant for the product(s) under consideration.
5 Testing to EN 13823
5.1 Test specimen and mounting
5.1.1 General comments
The different aspects of mounting and fixing are dealt with separately below. EN 13823 is a medium
scale test and, because of the effects of scaling on reaction to fire performance, it may not always be
appropriate (or even possible) to introduce all features of real-scale mounting and fixing in order to
achieve a test arrangement that adequately represents the product behaviour in one or more end-use
applications when exposed to a fire in the relevant fire scenario.
5.1.2 Rules in the reaction to fire standards
EN 13501-1:2002, 6.3:
“The potential contribution of a product to a fire does not only depend on its intrinsic properties and
the thermal attack, but also to a large extent on its end use application in the construction. Therefore,
it shall be tested so as to simulate its end use application.
NOTE It should be noted that as a consequence of a product being used in different end use applications,
the product may have different classifications relating to each application.”
“All construction products, except floorings, shall be tested in the vertical position for the purpose of
classification.”
EN 13823:2002, 5.1, concerning dimensions:
“The corner specimen consists of two wings, designated the short and long wings.”
The maximum thickness of a specimen is 200 mm.
Sheet products shall have the following dimensions:
a) short wing: (495 ± 5) mm x (1 500 ± 5) mm,
b) long wing: (1 000 ± 5) mm x (1 500 ± 5) mm.
NOTE If additional products are used to construct the specimen (in accordance with EN 13823:2002, 5.3.2),
the given dimensions refer to the total specimen dimensions.
“Specimens with a thickness of more than 200 mm shall be reduced
...
