26、 (E) 5 4 Principles 4.1 General principles Extended application is a prediction of the expected fire resistance performance of a fire resistant curtain walling or its components. It may be based either on interpolation between or extrapolation from test data according to EN 1364-3 and/or EN 1364-4.

27、Curtain walling function as integral systems in which the individual components (e.g. frames and fixing of the framing system (anchoring), infill panels, perimeter seals and vertical linear gap seals) are combined in such a way that they are effective in meeting the defined fire resistance criteria.

28、 In this document in addition to rules for the complete construction rules are defined for the components of curtain walling which are separately characterised as the framing system, the fixing of the framing system (anchoring), the infill panels and its fixing methods, the perimeter seal and the ve

29、rtical linear gap seals as well as the supporting construction (floor and walls). 4.2 Use of test evidence The applicant for the extended application shall either be the “owner” (i.e. sponsor) of all test data being submitted for the extension, or have written permission from the owner to use the su

30、bmitted test evidence. 4.3 Analysis of test results In order to maximise the extended field of application, it is important that the test reports shall record details of any premature integrity and / or insulation failure. Where a series of tests have been conducted, the field of extended applicatio

31、n shall be based on the lowest performance achieved from the complete series of tests unless premature failure has been attributed to one or more specific construction parameter variations. Where it has been possible, to identify specific parameter failures, the extended application for all other co

32、nstruction parameter variations can be based on the performance achieved after isolating the premature failure(s). 5 General rules 5.1 Fire resistance classification In the extended application, an increase in the classification time (e.g. from 30 min to 45 min) and changes to the fire resistance cl

33、assification (e.g. from E to EW to EI) are not permitted. 5.2 Combination of extended application Each extended application shall be the subject of a separate evaluation. Within this application it is allowed to produce a combination of extensions provided these combinations can be substantiated by

34、the supporting test evidence. 5.3 Overrun time For some rules to be applicable an overrun time in the fire test result compared to the envisaged classification time is required. The required overrun time is shown in Table 1. The overrun time is required for the following criteria: E classification:

35、integrity BS EN 15254-6:2014EN 15254-6:2014 (E) 6 EW classification: integrity and radiation EI classification: integrity and insulation Table 1 Overrun time Classification Time Overrun time 20 min minimum 3 min 30, 45 and 60 min minimum 6 min 90 min minimum 10 % of the classification time 6 Specifi

36、c rules for curtain walling type B 6.1 General Minimum one test according to EN 1364-3 is required. The assessment of the extended field of application may be based on additional test results from EN 1364-4 or EN 1364-3. The rules given in 6.2 to 6.4 apply to stick constructions only except where st

37、ated otherwise. Rules which result in higher weight of the curtain walling are only applicable if the fixing of the framing system used in practice has been designed for the higher load. The measured temperature at the fixing of the framing system shall be taken into account. 6.2 Rules for the compl

38、ete construction 6.2.1 Width for curtain walling with classification EW Test results are also valid for curtain walling with classification EW extending over one or more fire separating walls with a higher distance between the fire separating walls than the width of the tested construction if in add

39、ition to the criteria given in EN 1364-3 the radiation criterion is fulfilled for the resulting larger area. The radiation criterion shall be assessed using the rules given in A.1. The result of a calculation for a width equalling three times the tested width or minimum 9 m, whatever is larger, is a

40、pplicable to any larger width. An increase in width is only permitted by replicating the tested construction (especially type and dimensions of infill panels) in the same arrangement as tested. 6.2.2 Span length for curtain walling with classification EW Test results are also valid for curtain walli

41、ng with classification EW for a higher span length than used in the test if in addition to the criteria given in EN 1364-3 the radiation criterion is fulfilled for the resulting larger area. The radiation criterion shall be assessed using the rules given in A.1. This rule applies also to unitised co

42、nstructions. 6.2.3 Installation angle (vertical/sloped) Test results cover all installation angles between the maximum and minimum angle used in tests. This rule applies also to unitised constructions. 6.2.4 Vertically faceted curtain walling Test results cover all angles between vertically adjacent

43、 infill panels between the maximum and minimum angle used in tests. This rule applies also to unitised constructions. BS EN 15254-6:2014EN 15254-6:2014 (E) 7 6.2.5 Horizontally faceted curtain walling For corners and facet angles not covered by the rules given in EN 1364-3 the following rules apply:

44、 EI classification: Results from tests of faceted specimens according to EN 1364-3 using the test configurations A and B or alternatively E as illustrated in EN 1364-3:2014, Figure 8 and from minimum one test of a straight specimen cover all angles between horizontally adjacent infill panels at the

45、common mullion from 45 to 315 (see Figure 2) with classification EI (o i). E, EW classification: Results from tests of faceted specimens according to EN 1364-3 using the test configurations A, B, C and D or alternatively E and F as illustrated in EN 1364-3:2014, Figure 8 and from minimum one test of

46、 a straight specimen cover all angles between horizontally adjacent infill panels at the common mullion from 45 to 315 (see Figure 2) with classification E (o i) or EW (o i) respectively. 6.2.6 Inclusion of doors and/or windows Doors and/or windows may be included into a curtain walling and the rule

47、s of the EN 15269 series may be used provided an additional test as required by the standards of the EN 15269 series was conducted using the intended curtain walling as the associated supporting construction with the dimensions d 200 mm (see Figure 3). NOTE Dimensions d 500 mm are recommended. The f

48、ield of application of the classified curtain walling may be used when doors and/or windows are included in the curtain walling provided the test(s) including door(s) and/or window(s) has been conducted with internal fire exposure and surface S1 exposed to the fire as defined in EN 1364-3 and EN 136

49、4-4, and the smallest mullion size has been used in case of timber framing, or the largest mullion size has been used in case of metal framing These rules apply also to unitised constructions. 6.3 Framing system 6.3.1 Dimension of mullions and transoms All dimensions of mullions and transoms are covered between maximum and minimum tested. 6.3.2 Connection between mullions and transoms 6.3.2.1 Connection geometry For angles between mullions and transoms between a minimum of 80 degrees and a maximum of 100 degrees, see EN 1364-3.
