CEN/TS 16459:2019 (E)
Introduction
Fire tests on individual roofs/roof coverings are carried out in accordance with CEN/TS 1187. The
results from these tests can then be classified in accordance with EN 13501-5.
In order to derive classifications for similar roofs/roof coverings based on the data determined from
CEN/TS 1187, additional rules are needed.
These rules are direct application rules or extended application rules. Rules within the direct field of
application of test results are given in EN 13501-5 (these rules correspond to CEN/TS 1187).
This document outlines a procedure to develop rules for extended application and lists application rules
which have already been developed in Annex A to Annex D for test methods 1 to 4 from CEN/TS 1187,
where Annex A is related to test method 1, Annex B relates to test method 2, and so forth.
Annex A to Annex D have been developed based upon the available information and the roof systems in
the market. The objective of this document is to provide a methodology for optimizing the number of
tests required to cover the maximum field of application.
Annex E describes a procedure in which data acceptance principles for the submission of change
request to EXAP rules in Annex A to Annex D are set.
Whilst special attention has been focused on roofs typically comprising a support deck/substrate,
vapour barrier, insulation layer(s), membranes/roof coverings, there will be occasions when other
separating layers or intermediate layers will be needed to satisfy other roof characteristics. These
layers should be included in the consideration of the roof/the roof covering being classified.
NOTE Tests 1, 3 and 4 are carried out on a roof construction, whereas test 2 is done on a roof covering with
its substrate below, where the substrate may comprise various layers.
The decision route from the diagram below shows ways to determine which procedure to follow, when
classifying a roof/roof covering.
The solid line is compulsory, whereas the dotted line is optional.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in CEN/TS 1187:2012, EN 13501-5
and the following apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
• IEC Electropedia: available at http://www.electropedia.org/
• ISO Online browsing platform: available at https://www.iso.org/obp
3.1
adhesive
organic or inorganic material, e.g. polyurethane-based, bitumen-based, dispersion adhesive, glue which
is used to attach the surfaces of two or more products/components
Note 1 to entry: Adhesives or glues of the kind mentioned above could be applied separately and will thus form
a separate layer within the roof build-up, while factory pre-applied adhesives or glues are part of the specific
product/component forming a layer.
3.2
‘as tested’
term applicable for when rule does not exist for a specific parameter
3.3
binder content
amount of binding material (by % weight or % volume) within the product
Note 1 to entry: The binder could be inorganic or organic in nature. In the case of the latter, it will add a fire
load to the product containing the binder, and will be considered within the classification of products or product
groups. Within the substructure of products like mineral wool insulation products, particular felt layers, some
tiling products, and some multi-layer weather-proofing surface products the binder will typically be cured.
Note 2 to entry: The definition of this term does not apply to compound waterproofing sheets.
3.4
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
3.5
end-use application parameter
aspect of the mounting and fixing arrangement of a product reflecting/simulating its end-use
application, which can affect the fire performance
Example: type of substrate, fixing method, type and position of joints
3.6
extended field of application of test results
outcome of a process (involving the application of defined rules that can 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

CEN/TS 16459:2019 (E)
3.7
product group
range of roof products within defined limits of variability (defined by the manufacturer or a standard)
of the product parameters and, if relevant, end-use parameters, for which the reaction of the roof in end
use application to external fire exposure remains unchanged (does not get worse)
Note 1 to entry: As far as Clause 7 is concerned, product groups also include components for Annex A.
3.8
product parameter
aspect of a product which may vary and which can have an influence on the product’s fire performance
Examples: thickness, composition, density
3.9
roof pitch
inclination of the roof surface to the horizontal
Note 1 to entry: In the case of a tiled roof, the roof pitch is the rafter pitch since the tile pitch will be a few
degrees lower due to the overlaps.
3.10
separating layer
functional layer within a roof construction that is typically used to separate layers that do not match for
reason of chemical incompatibility, or it is needed as underlay, where applicable
Note 1 to entry: Separating layers are products such as fire protective layers (e.g. glass fleece); under-slating
(e.g. polymeric sheet; polymeric sheet reinforced by polymeric fibres; bituminised reinforced sheets); and others
such as bituminous kraft paper; aluminium sheet with covering (organic); and similar.
3.11

outcome of a testing process and its associated procedures detailed within a specific test standard
(which can include some processing of the results from the testing of a number of specimens)
Note 1 to entry: A test result is expressed in terms of one or more fire performance parameter(s).
3.13
type of product
products belonging to a subset of a product family (as defined in Guidance Paper G), grouping together
products having a similar nature and behaviour
Note 1 to entry: Examples of products having a similar nature include polymer modified bituminous roofing
felts, single-ply PVC membranes, cement based fibre boards, profiled metal roof sheets.
Note 2 to entry: Examples of products having a similar behaviour include products that melt or shrink under
flame attack, or decompose.

4 Product and end-use application parameters for roof coverings/roof systems
Table 1 is the list of product parameters and end-use application parameters that shall be taken into
account in Annex A to Annex D in making application rules. If other parameters are found to be relevant
for a given product, then these too should be considered in accordance with the principles of Clause 5
and Clause 6.
Annex A to Annex D list general rules and specific rules. The general rules are always valid, unless
specific rules exclude them explicitly for particular product groups and components. The general rules
are specified in A.1, A.2, B.1, B.2, C.1, C.2, D.1, and D.2.
The specific rules (A3, A4 – B3 – C3 – and D3) allow always additional extrapolations for particular
product groups and components, unless explicitly mentioned as a restriction to the general rules.
Relevant information may be contained in other documents, such as standards. This information may be
needed to define the end-use application parameters for the particular product (or product group) that
could influence the classification results in the external fire exposure tests to CEN/TS 1187, methods 1
to 4.

5 Extended application
5.1 General principles for extended application for roof coverings/roof systems
There are three options to establish rules for extended application. These are:
— by use of additional test results which, together with the initial test result, enables consideration of
a larger range of one or several product parameters and end-use application parameters;
— by use of tests results in combination with application of calculations methods (compare with 5.3)
relating the product and end-use application parameters to the fire performance;
— by use of historical data, see 5.4, and other relevant information e.g. data from previous tests.
NOTE Extended application rules are used to develop worst case ‘build ups’. Standard ‘build ups’ are
identified in the relevant product standards taking into account worst case ‘build ups’, e.g. where no specific test
information is available, indicative testing is used to establish the worst case scenario.
5.2 Extended application by additional tests
5.2.1 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
11
---------------------- Page: 13 ----------------------
SIST-TS CEN/TS 16459:2020
CEN/TS 16459:2019 (E)
of the product/end-use application parameter on which the extended application is required and to
know this relationship.
From this relationship it will be possible to predict the different levels of fire performance as a function
of the levels of the product/end-use application parameter and therefore the level of classification.
If there is an established rule about the relationship between the product/end-use parameter and the
fire performance (direct application) of a product or product group, it will be possible to optimize the
additional tests, as a function of the classification result which is expected, as follows:
— If the fire performance of the roof is known to be affected by the change of a product/end-use
application parameter(s) in a known direction, the test can be carried out on the parameter, the
variation of which is known to give the lowest performance in this instance for this product and/or
its end use- application, without changing the classification level.
— If it is known that the fire performance changes with a change of the product/end-use application
parameter but the relationship is not known, the number of additional tests shall be sufficient to
define the relationship (sufficient means that the relationship is adequately defined over the
intended range of parameter variation). For most relationships, this will require at least two
additional test results.
When a relationship has been established between the fire performance and a product/end-use
parameter, it shall be used to determine the classification of any product or product group covered by
this relationship.
5.2.2 Additional tests on several product/end-use application parameters
When more than one roof covering product parameter or end-use application parameter is to change at
the same time, and if the types of relationship are not known, it will be necessary to assess the tests
needed according to an experimental plan or an empirical approach. Then a more detailed series of
tests shall be performed to determine the relationship between these parameters, the external fire
exposure performance, and the resultant classification.
The study of this relationship shall be carried out from direct tests according to CEN/TS 1187,
methods 1, 2, 3 or 4 and Classification to EN 13501-5.
If the types of relationship between the fire performance and the product/end use application
parameter are not known, a series of tests will be necessary. The test series can be split into parts to get
firstly a result on the type of the relationship (qualitative result) and secondly information on the
quantitative relationship, if required.
In all cases the limits of field of application shall be complied with. When a limited approach is used, it
has to be kept in mind that the resulting relationships are only valid for the particular limits of the other
parameters that were kept constant in the test.
NOTE Results from other test methods can be used to determine which product parameter needs to be tested
in European Standard methods. Reports on extended application are given in accordance with EN 15725.
5.3 Extended application by calculation
For extended application by calculation, it is necessary to have (an) established calculation method(s)
shown to be valid for the intended range of parameter(s). This requires the calculation method to be
validated in accordance with 5.2.1 or 5.2.2.
NOTE So far, there are no verified and validated published calculation methods that have been established
and agreed for use.

CEN/TS 16459:2019 (E)
5.4 Guidance on the use of historical test data
When undertaking extended application (EXAP) a good understanding of the product performance in
fire is required. Some of this information will be known from the EN tests according to CEN/TS 1187,
however for some products there shall exist a record of test results against previous standards.
NOTE Under certain circumstances this information can be used as part of the EXAP procedure. This will help
to reduce the number of new tests which are required.
In applying these principles, the following conditions shall be met:
— Primary data shall be obtained from the relevant CEN/TS 1187, test 1 to 4.
6 Influence of product parameters and end-use application parameters on
external exposure to fire test performance
In Clause 4 of this document, Table 1 shows the list of product and end-use application parameters that
can influence the results from external fire exposure tests to roofs.
The following is an analysis of how each of these parameters can influence the test result for each of the
four different CEN/TS 1187 test methods, assuming that all other parameters are kept unchanged.
The fire testing in different European countries has historically been based on different exposure to
burni
