27、s and definitions given in EN 1996-1-2:2005 and the following apply. 3.1 unit grouping is defined in EN 1996-1-1 3.2 unfilled perpend joint vertical plain joint or joint with tongue and groove, not filled with mortar or adhesive 3.3 utilisation factor relation between the applied load on the test sp
28、ecimen and the design resistance without partial safety factors NOTE For design resistance see EN 1996-1-1 or EN 1996-3. 3.4 historical test data test data generated by fire resistance tests that have been undertaken by a Notified Test Laboratory in accordance with European and/or former and in acco
29、rdance with standards 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 T
30、he 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 uni
31、ts, 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 a
32、nd 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; 5 DIN EN 15080-12:2011-04 EN 15080-12:2011 (E) the type of perpend joint filled or unfilled perpend joint
33、, especially for unplastered walls; the use of finishes; the geometrical slenderness of the wall as defined in EN 1996-1-1; the level of the applied load; eccentricities; fire exposure of separating/non separating elements. (2) For the determination of values by consideration of test results, the in
34、terpretation 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 cons
35、idered 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
36、 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 an
37、d 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 po
38、ssible. 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 Necessary additional information For the classification accord
39、ing to these extended application rules additional information on material properties and additional measurements during the test procedure according to EN 1363-1, EN 1365-1 and EN 1363-2 or historic standard fire test methods are necessary: measurement of the deflection of the test specimen at leas
40、t in mid height, to allow for an extrapolation for height, see 5.5 (1); gross density, compressive strength and moisture content of the units; percentage of voids, web and shell thickness and combined thickness for perforated units; gross density and compressive strength of the mortar; 6 DIN EN 1508
41、0-12:2011-04 EN 15080-12:2011 (E) thickness of unfilled perpend joints in unplastered or unrendered walls; thickness and type of plaster or render in rendered walls; measurement of applied load on the test specimens; determination of the utilisation factor. NOTE The measurement of the temperature wi
42、thin 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 mm, 30 mm and 50 mm from the exposed side and then every 50 mm. 5 Rules for exten
43、ded application 5.1 Units (1) Extrapolations are only possible within the same type of material e.g. tests on clay unit masonry with units according to EN 771-1 can only be used for extrapolations for clay unit masonry. For lightweight aggregate concrete units according to EN 771-3 extrapolations ar
44、e only possible within lightweight aggregate concrete units. (2) The test results are valid for the tested type of unit. If solid units, i.e. group 1 units according to EN 1996-1-1 are tested, the results are only valid for group 1 units with the same or a smaller percentage of voids. (3) For vertic
45、ally perforated units (group 1, 2 and group 3 according to EN 1996-1-1), the test results can be applied for units with the same or a smaller percentage of voids. If the difference between the tested percentage of voids and the upper limit of the group in EN 1996-1-1 is less than 5 % of the overall
46、surface of the unit, test results are valid for all percentages of voids within that group. The tested percentage of voids can be rounded up to the next multiple of 5 %. (4) For vertically perforated units, the test results can be applied for units with the same or a higher thickness of webs and she
47、lls and for the same or higher values of the combined thickness. The value of the combined thickness can be rounded down to the next multiple of 10 mm/m. (5) Test results for vertically perforated units can be applied for solid units. (6) For the classification REI and R the test results are valid f
48、or the tested size of the unit and units larger in height, length and width. (7) For units with a length between 200 mm and 1000 mm, test results for a unit length from that range are valid for the whole range of unit lengths between 200 mm and 1000 mm. (8) For the classification REI-M, test results are valid for the tested length and width and units larger in length and width. It is not possible to extrapolate from tests on masonry walls with unit hei
