European foreword
This document (EN 15254-3:2019) has been prepared by Technical Committee CEN/TC 127
“Fire safety in buildings”, the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of
an identical text or by endorsement, at the latest by February 2020, and conflicting national
standards shall be withdrawn at the latest by February 2020.
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 has been prepared under a mandate 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 implement this European Standard: Austria, Belgium,
Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece,
Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,

Sweden, Switzerland, Turkey and the United Kingdom.
1 Scope
This document provides guidance and, where appropriate, defines procedures for variations of
certain parameters and factors associated with the design of lightweight partitions, which have
been tested in accordance with EN 1364-1, and classified according to EN 13501-2.
This document only applies to non-loadbearing lightweight partitions with a single steel
framework, provided with a lining on both sides of the steel framework. The lightweight
partition can be insulated with a mineral wool insulation within the partition cavity or not be
insulated.
This document does not apply to any other types of non-loadbearing lightweight partitions
considered in EN 1364-1.

3.1
lightweight partition
non-loadbearing wall that comprises a single steel framework, provided with a lining on both
sides of the steel framework
Note 1 to entry: The lightweight partition cavity can be insulated with a mineral wool insulation within
the partition cavity or not be insulated.
3.2
fire performance classification
classification of the lightweight partition in accordance with EN 13501-2 with only taking into
account the E and/or EI-classification
3.3
lining
layer(s) of boards fixed at each side to the steel framework of the lightweight partition
3.4
board
product with an A1 or A2 classification according to EN 13501-1 of rectangular shape and cross-
section in which the thickness is uniform and substantially smaller than the other dimensions,
and where the product is covered by a Technical Specification as defined in the CPR
3.5
mineral wool insulation
mineral wool as specified in EN 13162
3.6
metal framework
framework comprising steel profiles as specified in EN 14195
3.7
single steel framework
steel framework comprising only one row of steel studs
3.8
reference test
fire resistance test in accordance with EN 1363-1 (or EN 1363-2 when applicable) and
EN 1364-1, providing primary evidence, on which the extended application is to be based
3.9
additional test evidence
fire resistance test in accordance with EN 1363-1 (or EN 1363-2 when applicable) and
EN 1364-1, providing secondary evidence, on which the extended application is supported
3.10
overrun time
time of fire resistance in minutes beyond the fire performance classification time achieved in
the test
3.11
shape of the profiles of the metal framework
type of profile designated by the prefix-letter (e.g. C- or U-shaped)
4 Principles
4.1 General principles
Extended application is the 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 standard.
The extended application of the lightweight partition shall be based on the reference fire test
results performed according to EN 1364-1. Extended application reports shall be prepared
according to EN 15725.
When performing extended applications for a tested partition changes can occur either in
materials and/or in the construction. Both are dealt with in this standard. Table 1 gives an
overview of the changes which may be made in accordance with this extended application
standard.

4.2 Use of test evidence
4.2.1 General
The applicant for the extended application shall either be the “owner” (i.e. sponsor) of the
reference test and additional test evidence being submitted for the extension, or have written
permission from the owner to use the submitted test evidence.
4.2.2 Use of additional test evidence
Additional test evidence may be used to support extended application, for instance to evaluate
the influence of a particular component.
5 General rules
5.1 Fire performance classification
In the extended application, an increase in the classification time (e.g. from 30 min to 45 min)
shall not be permitted.
5.2 Combination of modifications
A combination of modifications mentioned in Table 1 is allowed.
5.3 Reference test
5.3.1 General
The basis for any extension is the reference test.
In case of an extended application described in Clause 6, the reference test shall have an
overrun time and/or a deflection less than the maximum allowed deflection if mentioned in the
relevant clause.
5.3.2 Overrun time
For some extended applications an overrun time is required. The required overrun time
depends on the intended classification time as shown in Table 2 below.
Table 2 — Required overrun time
Classification time Overrun time required
min
≤ 30 ≥ 3 min
> 30 and ≤ 60 ≥ 6 min
> 60 ≥ 10 % of the classification time
5.3.3 Maximum deflection
The maximum deflection of the lightweight partition is not in excess of h/30 with h being the
height of the tested lightweight partition.
