3 Terms and definitions
For the purposes of this Technical Specification, the following terms and definitions apply.
3.1
test result
outcome of a testing process and its associated procedures detailed within a specific test standard (which
may include some processing of the results from the testing of a number of specimens). A test result is
expressed in terms of one or more fire performance parameter(s)
3.2
direct field of application of test results
outcome of a process (involving the application of defined rules) whereby a test result is deemed to be equally
valid for variations in one or more of the product properties and/or intended end use applications
3.3
extended field of application of test results
outcome of a process (involving the application of defined rules that may incorporate calculation procedures)
that predicts, for a variation of a product property and/or its intended end use application(s), a test result on
the basis of one or more test results to the same test standard
3.4
classification
process defined in the Parts of EN 13501, whereby the fire performance parameters obtained from the results
of one test, or a set of tests, or from a process of extended application, are compared with limiting values for
those parameters that are set as criteria for achieving a certain classification. The relevant classes and related
criteria for fire resistance, for reaction to fire and for external fire exposure to roofs, are specified in
Commission Decisions (2000/367/EC, 2000/147/EC and 2001/671/EC respectively)
3.5
product
material, element or component, about which information is required (EN 13501-1). Refers to a construction
product, as defined by the Construction Products Directive (CPD), from an individual producer (i.e. the item to
which the CE marking applies) (EC Guidance Paper G)
3.6
product group
range of products within defined limits of variability (defined by the manufacturer or a technical specification)
of the product parameters and, if relevant, end-use parameters, for which the reaction to fire performance
remains unchanged (does not get worse)
3.7
product parameter
aspect of a product (for example thickness, composition, density) which may vary and which may or may not
have an influence on the product’s fire performance
3.8
end use application
real application of a product, in relation to all aspects that influence the behaviour of that product under
different fire situations. It covers aspects such as its quantity, its orientation, its position in relation to other
adjacent products and its method of fixing (EN 13501-1)
3.9
end-use application parameter
aspect of the mounting and fixing arrangement of a product reflecting/simulating its end use application (for
example type of substrate, fixing method, position and type of joints) which may or may not affect the fire
performance
4 Product and end-use application parameters
Table 1 gives examples of product parameters and end-use application parameters which may have to be
taken into account in developing direct and extended application rules. If other parameters are found to be
relevant for a given product, then these too should be considered.
The technical specification of the manufacturers has to define the end-use application parameters for the
particular product (group) which could influence the results of the reaction to fire tests in the fire tests.
Table 1 – Examples for product and end-use applications parameters (non-exhaustive list)
Product parameters End-use application parameters
Thickness Substrate or underlying construction
Density (or related parameter, e.g. Mounting method (e.g. directly onto substrate,
mass/square metre) onto wooden framework)
Colour Fixing method (e.g. adhesive, spacing and
type of fixings (screws, nails, etc.))
Surface coating/facing Type and position of joints
Composition of the product Presence of air gaps
Geometry and structure, product shape, Product orientation and geometry
number and composition of layers, …
Exposure to thermal attack
5 Direct application
5.1 General principles for direct application
This clause gives the principles of, and rules for, the development of direct application of tests results leading
to fire classification. It also lists the product parameters and end-use application parameters which need to be
taken into account. Parameters will need to be examined one by one depending on the product, and the limits
chosen to ensure that the basic principle, that the reaction to fire performance remains unchanged, holds.
Two possibilities exist for the development and implementation of direct application rules. The first is where
the rules are developed by, for example, a CEN product TC (or EOTA WG) in collaboration with CEN TC127
and then these rules are written into a harmonised technical specification. These rules/limits are then
applicable to all users of the technical specification. The second is where an individual manufacturer, in the
absence of written rules/limits in the technical specification, develops his own rules/limits for his particular
product or product group. These rules/limits then apply only to that manufacturer. In this case, however, the
manufacturer shall follow the guidelines given in this document.
In developing direct application rules, the concept of ‘lowest’ performance is important. This means that any
change to the product or end use application parameters which goes in the direction of improving the fire
performance can be relatively easily applied. Changes which go in the direction of lowering the fire
performance have to be treated with care, so as to ensure that there is no lowering of the product’s fire
performance sufficient to lead to a lowering of (additional) class or classification. Each fire performance
parameter shall be considered independently.
Direct application rules may apply to an individual product, or a product group, each in their end use
application(s).
While there are commercial and technical advantages in trying to develop direct application limits for all
products covered by a given harmonised technical specification, there is no specific requirement to do so. Nor
is there any specific requirement to define limits for all parameters of the product and its end use applications
parameters which have an effect on fire performance. Where parameters are not given in a harmonised
product specification, then manufacturers have to develop their own specific rules/ limits.
Annex A gives a more detailed presentation of possible effect of changes in product parameters on
classification, and B.1 gives examples of some direct application rules.
6 Extended application
6.1 General principles for extended application
Two options to establish rules for extended application are possible:
by use of additional tests results which, together with the initial test result, enables consideration of a
larger range of one or several product and end-use application parameters,
by use of tests results and additional calculations relating the product and end-use application parameters
to the fire performance.
6.2 Extended application by additional tests
6.2.1 Additional tests on one product/end-use application parameter
It is assumed that only one product/end-use application parameter changes and the other parameters remain
constant and that there is an initial test result on one value of the product/end-use application parameter.
If the relationship between the fire performance and the product/end-use application parameter is unknown,
the tests will be carried out on several variants of the parameter to assess the complete range of the
product/end-use application parameter on which the extended application is required and to know this
relationship. From this relationship
