4 Apparatus
4.1 Test specimen support
The test specimen support shall be rigid enough not to deflect tinder the cITed of impacts to which the test specimen is subjected
4.2 Witness foil
The witjws.s foil cst.s of a sheet of aluflUfliurn foil 0,02 mm thick weighing 54 gfm2, large enough to detect all splinters that might be ejected from the test specimen and with the edges of the foil iiunmntcd flI(ll, in a frame.
4.3 SplInters collecting box
4.4 Shooting equipment
4.4.1 Ballistic test equipment
The test may be conducted using either weapons or
pmof barrels.
4.4.2 Velocity nieasurlnp derice
The bullet velocity has to be measured with a nwasunng device which offers an accuracy of ±10 ni/s.
4.5 AmmunitIon
The shots shall be carried out with amnumnition corresponding to the required resistance class inThblel or2of EN l5L
5 ‘flst specimen
The nunilwr and types of test specimens reiptired are (k’terflhifled by the testing blX)rat(fiy from eXanUfiaUOfl of the (Irawitigs of the eoinpk’t.v winikw, door, shutter or blind.
The size of the test specimen(s) shall be agreed lwtween the testing laboratory and tlw applicant, and shall be such as to allow a valid ju(lgdnlent to be made on the bullet resistuice of windows, doors, shutters and blinds of vary g dlmnunsion.s.
Any mull shall be of uniform quality and shall be not smaller than 0,5 m X 0,5 ni., except where the saze of the complete infill is smaller. The attack face shall be clearly marked.
6 Procedure
(Li Installation of test specimen, witness foil and splinters collecting box
Install the test specimen. ensuring
a) the correct alignment between all components of the test s’pecinwn
b) that the flxü do not create stresses which may influence the test result in the test specimen; c) that the hardware, mechanisms and movable sashes remain (4Wfl11)1t’.
In the case of shutters or Ilusts, the shutter laths or moving blind must be moved as far as ixssible to one side so as to obtain the maximum edge clearance (which ran occur in use) between the leaf or blind and the fixed frame. This is required to ensure that the maxmumi edge deanmce which can occur in u.se is fired upon in the test
Position the witness foil 0,5 in behind the test specimen (dimension taken from the mean centre line of the test .specimen).
Position the splinters collecting box between the test specimen and the witness foil.
62 Selection of target areas
The choice of target arcns shall (kpdnd on the design of the overall window, door, shutter or blind and shall be derided by the testing lalxnatoiy on the basis of their analysis of that design whereby they shall luive identified the seti..itive areas, that is, those where the bullet tnjts1oty can:
a) nwet the least resistance or
b) bnng about (k’gra%lation such that it allows access to any opening mechanism which remains in operable condition; or
c) caww the tuiwanted opening of a window, door, shutter or blind.
NOTE The sensitive aireas of the window or (loaf Inune and shutter or blind are generally as follows:
I arnuoured or remfowrd areas (marked 1 arid 6 In annrxA,ttnwinrxfl,l,3andllniumrxC, l,6andIIin annex 1) and 1. 4.6, 7 and 9 In annex E).
These are generally made up by reliiforcemrnt of the pmflk’s constituting the frames or proflk.a and laths forming the curtain, the guide odis or the head box for a roller shutter or blind.
If different thicknesses of reinforeenwnt or (lifferenl materials are used in different parts of the sanie franw. each one of these I)arlN shall be Leste(L
For a door supplied (‘Oflhl)lCtC with ItS thflSIM)l(I. if 11w applicant asks for the threshold to be tested the horizontal gap at floor level shall be subjected to firing. Otherwise the test repolt summary shall state that this location OflPIS IX) bullet rtsistaitcp.
6.3 Arrangement of shots in the selected areas Each target area must receive three shots as deteniuned in 6.2. Target points shall be clearly marked on the test specinwn pnor to shooting. From exanunattomi of the drawings of the complete window, door. Shutter or blind, the testing taboratoiy shall detemune the target poinLs.
Three rircimnistances can be identified:
a) if the an’a is fcIifliciently large Hi proporuoli to the calibre of the ammunition (for example, on opaque infilLs or large profiles) the three target points shall be chosen on the same element and the striking distances shall be not less than 120 mm (see 1 and 6 in annex A, 1,6 and 11 in annex 1) and 1, 4. 6, 7 an(l 9 In annex E)
b) if the area is reduced to a line (for example butt joints, or junctions between profiles, and sashes or door leaves, uul franws and their inflILs), if the Line is long enough, the striking distance between the three target points shall be not less than 120 mm (see 3 in annex A, 2,3 and 12 in annex I) and 2, 3, 4 and 5 in annex E).
If not, the stnking (hstam shall be reduced to not less than three cahL)res.
If it is not possible to obtain three shots on the same line, the three shots shall be dMded between two or three Identical lines on the test swcinwn (see 5 and 7 in annex A, 2 in annex B or 5 and 7 in annex I)).
On pnNsnIsb’ (ertlfie(l infills installed in tiw test speeinwn, the junction between the infihl and rebate shall Lw fired upon with one shot at the centre of each of three sides of the inflil (see 8 in annex A or 3 in annex B);EN 1523-1998 pdf download.
