Bibliography 23Foreword

This document (EN 15725:2010) 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of an identical text or by endorsement, at the latest by December 2010, and conflicting national standards shall be withdrawn at the latest by December 2010.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.

According to the CEN/CENELEC Internal Regulations, the national standards organizations 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, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.Introduction

A construction product and a building element may be placed on the market with different thicknesses, densities, fixing conditions, substrates, etc. It is not practicable to test all combinations of different product parameters for the reaction to fire performance or fire resistance or external fire exposure performance, although these parameters may substantially influence the test result.

NOTE A building element is understood to be a defined construction component, e.g. wall, partition, floor, roof, beam or column.

Fire test methods may not include any information on direct application, the result obtained in the test is that which is reported. In a separate exercise it is possible to extend the field of application of the individual test results to a variation of the values of the different product parameters. This process of extended application uses rules which are essentially based on a worst case scenario and interpolation techniques. All information on extended field of application of reaction to fire results is given in CEN/TS 15117.

There are a number of practical limitations on the size and design of elements that can be tested by the standard methods of test for fire resistance. When these elements are larger, or are of a modified design, there is a necessity to be able to confirm their performance, i.e. whether the classification(s) given in the classification report in relation to the relevant criteria are maintained, without the ability of being able to test them. To achieve this, extended application standards for the various elements are under development.

1. Rules for extended application of results from external fire exposure to roof tests are also under development.Scope

This European Standard gives the procedures for preparing reports on the extended application process using the results of reaction to fire tests, fire resistance tests and external fire exposure to roof tests undertaken for fire classification of products and product families in accordance with the various parts of EN 13501.

This standard makes reference to ‘extended application standards’ throughout; wherever this term is used it refers to either a standard prepared by CEN/TC 127 'Fire safety in buildings’ or the relevant product standard which includes information on extended application. In some cases, where a standard is not yet published, relevant bodies may issue recommendations for use by Notified Bodies in attestation procedures for CE marking under the Construction Products Directive (CPD), httD://ec.europa.eu/enterprise/newaDproach/nando/.

The European system currently permits extended application rules to be included in technical specifications. CEN Technical Committees and EOTA Working groups producing these rules are asked to seek the guidance of CEN/TC 127 to ensure that their rules comply with standards prepared by CEN/TC 127. In cases where extended application rules in harmonised EN product standards and ETAs do not comply with standards prepared by CEN/TC 127 the CEN ВТ should be informed.

material, element or component about which information is required

[EN 13501-1:2007+A1:2009]

product family

range of products within defined limits of variability (defined by the manufacturer or a technical specification) of the product parameters and, if relevant, end use parameters, for which the fire performance remains unchanged (i.e. does not get worse)

way the product is incorporated into the building, e.g. jointing, fixing and position with respect to adjacent products

NOTE The mounting and fixing conditions for testing reflect the end use conditions.

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) and expressed in terms of one or more fire performance parameter(s)

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

3.9

extended field of application of test results

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 test standard

3.10

extended application report

document reporting extended application results, including all details of the process leading to those results

3.12

agreed expert opinion

results of a dialogue between a group of experts who are accepted by their peers as being knowledgeable in a particular fire test and the performance of products in that test. Such dialogue shall take place within a recognised and properly constituted forum, such as CEN/TC 127. These agreed expert opinions are then transformed into rules that may form the basis of extended application. Agreed expert opinion will lead notified bodies to a classification, suitable for the application of CE-marking.

3.13

expert judgement

view of a recognised expert in a particular fire test, and performance of products in that test, that may be used for the purpose of interpreting or applying results of that test in connection with the application of the particular product into parts of works for the purposes of satisfaction of national regulations

NOTE Expert judgement cannot form any part of extended application for CE marking, but may be obtained by manufacturers as a voluntary judgement outside of CE-marking.

3.14

constructional parameter

design and construction that may be varied and which may result in a change in the fire resistance performance, e g. in a stud framed separating element a change in the dimensions of a stud

3.15

thermal and mechanical parameters

conditions of a test that may influence the classification given, e g. the pressure differential that will exist at the top of a larger element than existed at the top of the specimen when tested

3.16

factor

variation that may be applied to a parameter, e g. a change in the stiffness as a result of a dimensional change in the stud

3.17

factor influence

potential cause of a change in the fire resistance when the factor is changed, e.g. an increase in the loadbearing capacity A as a result of an increase in stiffness

4. Role of extended application in the classification process

There are two possible routes to obtaining a fire classification. The first one is to undertake fire tests in accordance with the relevant EN fire test methods given in one of the parts of EN 13501. From the test report(s) obtained, a classification report can be prepared. Secondly an extended application can be undertaken using test reports and other relevant data, and carried out in accordance with the relevant EN extended application standard. From this process an extended application report is prepared in conformity with this standard.

An extended application report is equivalent to a test report in that it then forms the basis for preparing a classification report. This process is illustrated in Figure 1.

^<a) In some cases, where a standard is not yet published, relevant bodies may issue recommendations, available for use by Notified Bodies in attestation procedures for CE marking under the Construction Products Directive, (http://ec.europa.eu/enterprise/newapproach/nando/).

Figure 1 — Role of extended application in the fire classification process

5. Principles of establishing the field of application

   1. General

Following a fire test there are two fields of application that can be derived from the result, direct field of application and extended field of application.

Direct application of results from reaction to fire tests is undertaken in accordance with EN 13501-1:2007+A1 using results from the relevant EN classification test methods and taking into account information on substrates given in EN 13238 and information in CEN/TS 15117 and any other relevant European Technical Specification.

The rules governing the direct field of application of results from fire resistance tests are given in the individual test methods.

The rules governing the direct field of application of results from external fire exposure to roof tests are given in EN 13501-5:2005+A1.

Extended application shall be undertaken by the laboratory which has carried out the relevant fire tests. If test results are to be used from more than one laboratory, then the extended application shall be undertaken by one of these laboratories and consultation should be made with the other laboratories.

NOTE When extended application is intended to be used for CE marking purposes the intervention of a Notified Body is mandatory.

When a Notified Body is requested to produce an EXAP Report which requires the consideration of evidence from third parties (e g. test reports, DIRAP reports, other EXAP reports, etc.), such evidence shall only be used when permission has been obtained from the original sponsor/owner of that evidence.

Extended application shall be undertaken in accordance with the relevant EN extended application standard. Extended application shall be based on test methods in accordance with the relevant European standards or ETAG, which may be supplemented by:

— documents mentioned in Figure 1

Information on undertaking extended application from the results of reaction to fire tests and an explanation of the influence of product and end use parameters on reaction to fire performance is given in CEN/TS 15117.

The extended field of application analysis is an additional process that has to be applied for and is not granted automatically following a fire resistance test. An extended field of application analysis is required when the application of the element differs from the test specimen and is not covered by the direct field of application. Examples for the variations to be considered when performing an extended application are identified in 5.3.3.2. Details of undertaking extended application of results of fire resistance tests are covered in the relevant European standards for extended application and other documents referred to in Figure 1. The methodology adopted in the prediction of fire resistance performance is based on universally accepted rules, some of which incorporate calculation methods and some of which may be 'agreed expert opinion’ set out in the relevant extended application standard and other documents referred to in Figure 1. The basis of development of the rules varies according to the different parameters relevant for different elements.

Primary evidence for undertaking extended application shall have been generated from full tests carried out only to European standards or ETAGs. Secondary evidence, e.g. indicative tests to ENs or prENs, may also be used in support of extended application in certain cases (see 5.3.1). The acceptability of using indicative tests is given in the relevant extended application standard and varies according to the different parameters relevant for different elements.

Examples of aspects considered in preparing the extended application documents as given in Figure 1 are given below.

1. Examples of thermal and mechanical parameters:

1. The load on a load bearing element;

2. The boundary conditions applied to an element at its ends or edges;

3. The thermal action or the number of faces exposed;

4. The pressure differential due to height;

5. The mechanical impact (if appropriate);

6. The orientation of an element, e.g. a change from vertical to sloping.

2. Examples of constructional parameters:

1. The construction of the element (e.g. thickness) and the method or the materials used in the construction of the element;

2. Any change in the dimensions of the element (normally larger) from that tested to that under consideration;

3. The introduction of, or any variations to, an aperture in a separating element;

4. The orientation of an asymmetric element in respect of the fire exposure.

Information on undertaking extended application of the results from external fire exposure to roof tests and an explanation of the influence of product and end use parameters on external fire exposure to roofs performance will be given in a document under preparation.
