This Technical Specification (CEN/TS) was approved by CEN on 16 September 2019 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to
submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS
available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in
parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,

European foreword
This document (CEN/TS 16459:2019) has been prepared by Technical Committee CEN/TC 127 “Fire
safety in buildings”, the secretariat of which is held by BSI.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes CEN/TS 16459:2013.
CEN/TS 16459:2013:
— the Normative references have been updated;
— a new definition was added in 3.1 (term „layer“);
— the requirements to involve notified bodies in the preparation of EXAP rules was deleted from 5.4
and general;
— under clause 7, Table 5 was updated according to the insertion of new EXAP rules in different
Annexes and sections thereof, i.e. (see next lines);
— 3.5 Roof lights and roof windows: set of specific rules was moved to Annex A;
— 3.11 Liquid applied roof waterproofing kits: set of specific rules was moved to Annex A;
— the rules for the parameter „Application on existing roofs (“renovation”)“ have been reconsidered
for all Annexes and were amended and/or specified in more detail;
— Annex E „Data acceptance principles for the submission of change request to EXAP rules in Annex A
to Annex D“ is completely new: This annex sets out to establish the principles upon which data
presented to CEN TC127/WG 5 (External fire exposure of roofs and roof coverings) will be
reviewed by the committee or its nominated adhoc Sub Group for consideration.
This document has been prepared under a standardization request given to CEN by the European
Commission and the European Free Trade Association.
According to the CEN/CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the
United Kingdom.
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.

1 Scope
This document gives guidance on the process and development of extended fields of application using
test results obtained from CEN/TS 1187, tests 1 to 4, and included in test reports, and other relevant
information in order to evaluate and classify the performance of roofs/roof coverings. This document
provides a methodology to consider the possible effect(s) on classification to EN 13501-5 from single or
multiple changes to the individual product and end-use application parameters of the roof/roof
covering.
Specific application guidance is given in Annex A, Annex B, Annex C and Annex D for CEN/TS 1187,
tests 1 to 4 respectively.
