7.5 Induced movement
The various possiblities to impose mechanically induced movement, induding standard conditions, are described in Annex 9
8 Conditioning
The test construction shall be conditioned in accordance with EN 1363-1.
9 Application of instrumentation
9.1 General
The control, monitowing and recording equipment shall be in accordance with EN 1363-1.
9.2 Thermocouples
9.2.1 Furnace thermocouples
Plate thermometers shall be provided ii accordance with EN 1363-i The plate thermometer shall be located ii a plane 100 nn from the exposed face of the separating etement, At least one thermometer shal be provided for every 1,5 m2 of the heated area of the test construction. si.tject to a nnimum number of four thermometers for each test construction, These thermometers shall be symmetrically chstflbuted with respect to the heated area of the test construction.
For vertical test constructions, the plate thermometers shall be oriented so that side laces the walls of the furnace opposite the lest construction being evaluated.
For horizontally onented test constructions, side of the plate thermometers positioned below the test construction being evaluated shall face the floor of the furnace.
9.2.2 Unexposed face thermocouples
Surface temperature measurements and the thermocouples shall be Ni accordance with EN 1363-1. The test specimen thermocouples shall be at the centre line of the linear joint seal. Figures 5 to 11 and 13 show examples of thermocouple application.
In the case of non-planar surfaces the disc and the pad shall be deformed to follow the surface profile. In the case of smal sections it is permissible to reduce the size of the pad to a mimmum dimension of 12 mm. If a Inear joint seal is recessed from the unexposed face of the supporting construction and the bnear joint seal is less than 12 mm wide, thermocouples shal be Inslaled on the supporting construction at a distance of not more than 15mm from the joint seal (see FIgure 13).
If a potential weak point can be identified, ad&tional fixed thermocouples shal be attached to this pant, e.g. over a splice.
Where it Is impractical to attach thermocouples because of the nature of the surface of the linear joint seal (wtiich may change signwltcanlty during the test penod). carefii use may be made of a roving thermocouple.
9.2.3 Roving thermocouple
The information obtained on unexposed face surface temperatures shall be supplemented by additional data derived from measurements obtained using a roving thermocouple applied to identify any local “hot spots” in accordance with EN 1363-1. If it is determined that the roving thermocouple may damage the test specimen, it shall not be used and the reason noted in the test report.
9.3 Deformation and deflection
Deformations of the supporting construction shall be measured and recorded. Instrumentation for the deflection measurement of the supporting construction shall be located so as to provide data in terms of the amount and rate of deflection during and, where appropriate, after the fire test.
9.4 Integrity measurement
The integrity of the specimen shall be assessed as described in EN 1363-1, except that gap gauges shall not
be used.
10 Test procedure
10.1 General
Tests shall be carried out according to the procedures given in EN 1363-1.
Tests can be carried out either with or without movement. In the case of tests with movement it can be in the plane of the supporting construction (lateral) or normal to it (shear), or it can be any other movement appropriate to the intended application. The movement can be imposed prior to test or during the test.
Depending on the required field of application (see Clause 13) tests shall be carried out in accordance with the appropriate subclause of Annex A or the appropriate subclause of Annex B.
NOTE The test should be run until failure of all the linear point seals within a test construction.
10.2 Installation of test construction
When the conditioning procedures are satisfied, the test construction shall be mounted to form the vertical or horizontal face of the test furnace as appropriate. Measuflng equipment and ancillary apparatus shall be provided in accordance with this European Standard.
10.3 Mechanically induced movement of the test specimen
If the test specimen is to be tested with mechanically induced movement, this shall be carried out according to the provisions given in Annex B.
The sponsor shall specify the type of movement (e.g. lateral, shear), if movement is applied prior to or during the test, the movement capability and the anticipated fire resistance time.
10.4 Measurements and observations
Subject to the modifications referred to in Clause 9, measurements and observations during the test shall be made in accordance with EN 1363-1.
