1 Scope
This Part of prEN 15254-1 identifies the general parameters and factors that affect the fire resistance
of non-loadbearing walls (partitions) and need to be taken into account when considering extended
application of results of non-loadbearing walls tested in accordance with EN 1364: 1. It also defines
the general rules and principles to which can be applied to establish the resultant influence of a
variation in one or more parameters and to determine the limits of the field of extended application
together with the content of the report of the study. The standard is applicable to the following types of
non-loadbearing walls:
Part 2
Masonry and gypsum blocks:
Concrete blocks
Bricks
Gypsum blocks
Aerated concrete blocks
Aerated concrete panels
Part 3
Lightweight partition:
Boards + studs (metal or timber) + insulation + voids
Part 4
Glazed construction:
Panes
Part 5
Metal sandwich panel construction
Part 6
Demountable partitions
Some examples of the above partitions are given in figures in the specific parts.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other
publications. These normative references are cited at the appropriate places in the text and the
publications are listed hereafter. For dated references, subsequent amendments to or revisions of any
of these publications apply to this European Standard only when incorporated in it by amendment or
revision. For undated references the latest edition of the publication referred to applies (including
amendments).

3 Definitions
For the purpose of this part of prEN 15254-1 the definitions given in EN ISO 13943, EN 1363-1, EN
1365-3 and prEN 15254-1, together with the following apply:
3.1
reference scenario
all the fire test conditions and constructional details of the test specimen for which observations of fire
behaviour, changes in temperatures, dimensions and displacement in the test specimen are given in
the test report
3.2
reference test
fire resistance test in accordance with EN 1364-1, and where applicable EN 1363-2, on which the
extended application is based and the results of which are used as the main source of data for the
extended application
3.3
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)
3.4
constructional parameter
aspect of the reference specimen that varies for the purpose of the prEN 15254-1 (other needs in
practice) and may change of the fire resistance performance
3.5
factor
one of the possible variations that may be applied to a parameter
3.6
factor influence
one of the potential causes of a change in the fire resistance due to a factor
3.7
direct field of application of test results
outcome of a process (involving the application of a defined rule) whereby a single test result,
expressed in terms of all the relevant fire performance parameters, is deemed to be equally valid for
variations in or more of the product properties
3.8
extended field of application of test results
outcome of the process (involving the application of defined rules that may incorporate calculation
procedures) that predicts the result of a test, expressed in terms of all the relevant fire performance
parameters, on the basis of one or more test results to the specific test method and related to the
particular product (including variations of the product properties)
3.9
classification
process defined in EN 13501-2, 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 classific
