The extended application of the wall shall be based on the reference fire test results performed according to EN 1364-1 and may be complemented by one or more additional small or full scale tests or by historical data. If historical data are used they shall comply with the rules given in this document. 4.2 Assumptions in the extended application The following assumptions are considered when evaluating extended applications for sandwich panels:  The wall is required to possess fire resistance in the end-use condition; relevant classes are given in EN 13501-2;  The wall is assumed to be exposed on the entire face of one side to the standardised heating conditions given in the EN 1363-1 fire resistance test specification;  The structure above and below the wall does not deflect vertically during the fire exposure period; this simulates the non-deflecting nature of the test frame which forms part of the furnace test apparatus; NOTE In reality constructions deflect and this should be taken into account when designing the building and planning the constructional details so that no vertical loads are applied to the wall.  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 panels are attached;  The support structure has at least the same loadbearing capacity R of the resistance to fire performance as the wall regarding integrity; SIST EN 15254-5:2010

NOTE Annex A illustrates a typical behaviour of panels. 5 Rules for extended applications of the tested product 5.1 General When performing extended applications for a tested wall 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 given in 5.2 and 5.3.

5.2 Variations in the materials of the product 5.2.1 General Sandwich panels consist of three main materials (facing metal sheets, adhesive and core material). In the case of autoadhesively bonded panels the foamed core material also form the adhesive layer during the foaming process.
