Add the following paragraphs:
“7.5.2.2.2 Mounting and fixing provisions for EN 13823
7.5.2.2.2.1 End use applications
The end uses covered by the standardised mounting and fixing are fibre cement profiled sheets and fittings
used as the external layer for discontinuously laid roof coverings, used as internal and external wall finishes
and used as external ceiling finishes. In these end uses, the side of the product directed away from the fire is
normally in contact with air and the cavity behind may or may not be filled with thermal insulation.
7.5.2.2.2.2 Test specimen
Products used for the construction of the test assembly are fibre cement profiled sheets with standard
dimensions of length, width and thickness. They are cut to size to accommodate the dimensions of the test
assembly. They include all facings and/or coatings that are normally applied to the product as it is placed on
the market.
7.5.2.2.2.3 Test assembly
7.5.2.2.2.3.1 Dimensions
The test assembly is a corner set up made of two timber frame supporting constructions each with a height of
1,5 m to which the fibre cement profiled sheets are fixed. One frame forms a long wing (1,0 m) the other frame
forms a short wing (0,5 m). Further information is given in Figures 1, 2, 3, 4 and 5.
