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

(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 units at the start 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);
 percentage of voids, web and shell thickness and combined thickness according to EN 772-16 for perforated units;  gross dry density and compressive strength of the mortar;  thickness of unfilled perpend joints in unplastered or unrendered walls;  thickness and type of plaster or render in rendered walls. NOTE The measurement of the temperature within the test specimen at least in mid height across the wall thickness is advised to allow for a future calculation of fire resistances according to EN 1996-1-2. Thermocouples should be placed at least in depths of 10, 30 and 50 mm from the exposed side and then every 50 mm.
