41、d 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

42、 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 fr

43、om metal faced sandwich panels used as a nonloadbearing 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.4.2 Assumptions in the extended applicationThe f

44、ollowing assumptions are considered when evaluating extended applications for sandwich panels:a) the ceiling is required to provide fire resistance and shall be classified according to EN 13501-2;b) the ceiling is assumed to be exposed on one side (either from above or below) to the standardized hea

45、ting conditions given in the EN 1363-1 fire resistance test specification or to alternative and additional procedures given in the EN 13632;c) the supporting construction to which the ceiling is fixed does not significantly deflect during the fire exposure period;6 BS EN 152547:2018EN 15254-7:2018 (

46、E)d) after delamination of the fire exposed facing, the dead load of the panels is carried by a support structure to which the ends of the sandwich panels are attached; the forces from the dead load will be distributed to the support structure by the panel fixings from which loadbearing capacity sha

47、ll be evaluated;e) the support structure has at least the same loadbearing capacity, R, of the fire resistance performance as the sandwich panel ceiling regarding insulation and integrity, if the support structure is on the fire exposed side in end use condition;f) the self weight of the facing and

48、core is calculated from the volume and density of the materials;g) the calculation of the reduction in the strength properties of steel at elevated temperature shall be in accordance with EN 199312.5 Rules for extended applications of the tested product/construction5.1 GeneralWhen performing extende

49、d applications for a tested ceiling, changes can occur either in the materials and/or in the construction. Both are dealt with in this standard. Table 1 and Table 2 list the changes which may or may not be made in an extended application assessment. The rules for the changes are either given in Table 1 or Table 2 or in 5.2 and 5.3.Table 1 Material changes relevant to extended applicationParameter Factors Factor influence on performance RulesIntegrity E Insulation IChanges in me
