BS EN 15254-7:2018 pdf download.Extended application of results from fire resistance tests – Non-loadbearing ceilings
1 Scope
This document defines rules for extended applications, provides guidance, and, where appropriate,specifies procedures, for variations of certain parameters and factors associated with the design of internal non-loadbearing ceilings constructed of metal faced sandwich panels that have been tested in accordance with EN 1364-2, which could generate a classification in accordance with EN 13501-2.This document applies to self-supporting, double skin metal faced sandwich panels, which have an insulating core bonded to both facings as defined in EN 14509.

4 Establishing the field of extended application
4.1 General
An extended application analysis is required when the application differs in one or more parameters from the one tested and described in the test report and/or in the classification document, and which is not (fully) covered by the field of direct application of the classification document. Extended application is a prediction of the expected fire resistance of fire resistant metal faced sandwich panels. It may be based on interpolation between or extrapolation from test data. The fundamental consideration shall be that the fire resistant metal faced sandwich panels after extension would achieve the required fire performance if it were to be tested according to EN 1364-2. The extended application of test results from metal faced sandwich panels used as a non-loadbearing ceiling shall be based on the reference fire test results performed according to EN 1364-2 and may be complemented by one or more additional tests. The general rules in EN 15725 shall be followed.
