Extended application of results from fire resistance tests - Non- loadbearing walls - Part 1: General

This part 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 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.

Foreword

This document (prEN 15254-1:2005) has been prepared by Technical Committee CEN/TC 127 “Fire

safety in buildings”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.

This document has been prepared under a mandate given to CEN by the European Commission and

the European Free Trade Association, and supports essential requirements of EU Directive(s).

For relationship with EU Directive(s), see informative annex A, which is an integral part of this

document.

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

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

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
