NOTE 1 Previously existing test data is acceptable even though the test may not have been carried out using the plate thermometer as long as the necessary additional information, (see 4.3) is available. This data can only be used as described in this European Standard.
NOTE 2 The temperature-time curve used is based on the one specified in EN 1363-1, which is also defined in
ISO 834. 3.5 moisture content of units difference between the density of the units at the beginning of the fire test and the gross dry density of the units, related to the gross dry density of the units, in percent by mass 4 General principles 4.1 General (1) The fire behaviour of load bearing masonry mainly depends on: the masonry unit material - clay, calcium silicate, autoclaved aerated concrete, dense/lightweight aggregate concrete; the type of unit - solid or hollow (type of holes, percentage and direction of holes), shell and web thickness; the unit dimensions; the unit gross density; the unit compressive strength; the type of mortar - general purpose, thin layer or lightweight mortar; SIST EN 15080-12:2011
fire exposure of separating/non separating elements. (2) For the determination of values by consideration of test results, the interpretation of any existing fire test results has to be based on the requirements for the relevant test method from EN 1363-1, EN 1363-2 and EN 1365-1.
(3) For the evaluation of use of previously existing data, differences between the test methods, have to be considered.
NOTE Differences to be considered are for example material properties, specimen dimensions, utilisation factor based on maximum loading, eccentricities, etc. (4) To establish the extended application, the rules given in Clause 5 shall be followed for each of the given parameters. (5) Extrapolations exceeding the rules of this European Standard are possible, provided that tests give evidence to do so. Such extrapolations have to be specified in the report, see Clause 6. 4.2 Classifications (1) All the given rules are always valid for the same classification. (2) Extrapolation is possible for different wall thicknesses and geometries, different unit densities, compressive strengths, perforation patterns and sizes, different types of masonry mortar, different types of external covering, different load levels and eccentricities. (3) An extrapolation for higher fire resistances or from REI tests to REI-M or R is not possible. NOTE 1 In some cases, there are different extended application rules given for the classifications R, REI and REI-M.
NOTE 2 In addition, the rules given in this European Standard for REI tests also apply for RE and REW tests. 4.3 Necessa
