EN 15254-2:2009 (E) 5 3 Definitions For the purpose of this standard, the definitions given in EN 1996-1-2:2005 and the following, apply. 3.1 unfilled perpend joints vertical plain joints or joints with tongue and groove, not filled with mortar or adhesive
3.2 historic test data test data generated by fire resistance tests that have been undertaken by an accredited and/or Notified Test Laboratory or by a laboratory officially recognised by national fire authorities in accordance with European and/or former and current national standards based on the temperature-time curve identical to the one specified in EN 1363-1 (and defined in ISO 834)
NOTE 1 Previously existing test data is acceptable even though the test may not have been carried out using the plate thermometer.
NOTE 2 This data may only be used as described in this European Standard. NOTE 3 Previously existing test data is acceptable provided that there has been no change to the product since this data was generated.
3.3 reference test fire resistance test in accordance with EN 1364-1, and where applicable EN 1363-2, on which the extended application is based and the results of which are used as the main source of data for the extended application 3.4 test result outcome of a testing process and its associated procedures detailed within a specific test standard (which may include some processing of the results from the testing of a number of specimens) NOTE A test result is expressed in terms of one or more fire performance parameter(s). 4 General principles 4.1 General (1) The fire resistance behaviour of masonry mainly depends on: masonry unit material - clay, calcium silicate, autoclaved aerated concrete, dense/lightweight aggregate concrete or gypsum; type of unit - solid or hollow (type of holes, percentage and direction of holes), shell and web thickness; dimensions of units, especially the height; gross density of units; strength of units; type of mortar - general purpose, thin layer or lightweight mortar; type of perpend joint – filled or unfilled perpend joint, especially for unplastered walls; use of finishes; SIST EN 15254-2:2009
EN 15254-2:2009 (E) 6 geometrical slenderness of the wall, as defined in EN 1996-1-1; length of the wall between vertical stiffeners. (2) For the determination of values by consideration of test results, the interpretation of any existing fire test result has to be based on the requirements for the relevant test method from EN 1364-1. For the evaluation of historic test data, differences between the test methods, in particular, fixed ends, free ends or one fixed end and one partly free end with respect to both directions (horizontal and vertical) have to be considered. Any historical test data shall be obtained by a comparable or a more onerous test method than in EN 1364-1 on a wall which is of the same or of worse resistance to fire performance. (3) Extrapolations are only possible within the same type of material – e.g. tests on clay unit masonry with units according to EN 771-1 may only be used for extrapolations for clay unit masonry. (4) To establish the extended application, the rules given in Clause 5 shall be followed for each of the given parameters.
(5) Whenever a parameter change goes beyond the limits defined in this document, a new reference test is needed. 4.2 Classifications In some cases there are different extended application rules given for the classifications EI, E and E-W respectively and for the classification EI-M as defined in EN 13501-2. 4.3 Additional information For the classification according to these extended application rules additional information on material properties and additional measurements during the test procedure according to EN 1363-1, EN 1364-1 and EN 1363-2 or historic standard national fire test methods are necessary: measurement of the deflection of the test specimen at least in mid height, to allow for an extrapolation for height, see 5.5 4; gross dry density, compressive strength and moisture content of the units (i.e. difference between density of the un
