Nastavitev in umerjanje
To perform the headform test the phantom head is fixed to the cross arm of the guide system (figure 2.2) and moved to the required drop height by means of a lifting device.
Za izvajanje preskusa z modelom glave se model glave pritrdi na prečni nosilec sistema za vodenje (slika 2.2) in z dvižno napravo dvigne na zahtevano višino pada.
During the headform test the cross arm with the phantom head is released.
Pri preskusu z modelom glave se prečni nosilec z modelom glave odklopi od dvižne naprave.
After passing the height adjustable light barrier the phantom head is released from the cross arm, the cross arm’s fall is dampened and the phantom head falls onto the sample.
Prečni nosilec z modelom glave prosto pada in ko doseže svetlobno zaporo, ki je nastavljiva po višini, se model odklopi od prečnega nosilca in prosto pade na vzorec, pri čemer padanje prečnega nosilca zaustavijo dušilniki.
No impulse may be given to the phantom head by the drop appliance or by the measuring cable, so that it is accelerated only by gravity and falls vertically.
Na padanje modela glave ne sme vplivati preskusna naprava ali povezovalni kabel, tako da model pospešuje le zaradi sile težnosti in pada navpično.

Test apparatus for the headform experiment with deceleration measurement
Preskusna oprema za preskus z modelom glave z merjenjem pojemka
Measuring device which allows to determine HIC-values with the headform described under paragraph 3.2.1.
Merilna naprava, ki omogoča določitev vrednosti HIC z modelom glave iz odstavka 3.2.1.
Equipment to calibrate the phantom head
Oprema za umerjanje modela glave
The drop appliance must allow drop heights between 50 mm and 254 mm to be adjusted exactly to within 1 mm. A guide system is not necessary for these small drop heights.
Preskusna naprava mora omogočiti nastavitev višin pada od 50 mm do 254 mm z natančnostjo do 1 mm. Sistem za vodenje pri tako majhnih višinah pada ni potreben.
A steel impact plate which is made of steel is 600 mm × 600 mm in size and at least 50 mm thick.
Jeklena udarna plošča mora biti velika 600 mm × 600 mm in debela vsaj 50 mm.
The impact surface must be polished:
Udarna površina mora biti polirana:

površinska hrapavost Rmax = 1 μm, toleranca ploskosti t = 0,05 mm.
Calibration and adjustment of the phantom head
Umerjanje in nastavitev modela glave
Before each test series and no later than each 50 tests within a series, the phantom head must be calibrated and adjusted if necessary.
Model glave je treba pred vsako serijo preskusov in po največ 50 preskusih iz ene serije umeriti in po potrebi nastaviti.
The impact plate must be clean and dry and during the test must lie non-positively on a concrete base.
Udarna plošča mora biti čista in suha ter mora med preskusom ležati nepritrjena na betonski podlagi.
The phantom head is allowed to hit the impact plate vertically.
Model glave se spusti tako, da udari navpično na udarno ploščo.
The drop heights (measured from the lowest point of the phantom head to the surface of the impact plate) are 50, 100, 150 and 254 mm. The deceleration curves should be recorded.
Višine pada (merjene od najnižje točke modela glave do površine udarne plošče) so 50, 100, 150 in 254 mm. Krivulje pojemka je treba zabeležiti.
The greatest deceleration az from the various drop heights on the z-axis must lie within the limits given in the table:
Največji pojemek az s posameznih višin pada na os z mora biti znotraj mejnih vrednosti iz naslednje tabele:
Drop height
Višina pada
Greatest deceleration az as a multiple of acceleration due to gravity g
Največji pojemek az kot večkratnik pospeška zaradi sile težnosti g
The deceleration curves should be based on a unimodal vibration.
Krivulje pojemka morajo temeljiti na unimodalnem nihanju.
The deceleration curve of the drop height of 254 mm must run at least 1,2 ms and at most 1.5 ms over 100 g.
Krivulja pojemka pri višini pada 254 mm mora biti najmanj 1,2 ms in največ 1,5 ms nad 100 g.
If the requirements given in paragraph 3.2.2.3 are not met, the elastic properties of the phantom head must be adjusted by varying the thickness of the intermediate ring (13) in the base plate (24).
Če zahteve iz odstavka 3.2.2.3 niso izpolnjene, je treba nastaviti lastnosti prožnosti modela glave tako, da se spremeni debelina vmesnega obroča (13) v osnovni plošči (24).
Corrections can be carried out by adjusting the three self-locking hexagonal nuts (8) on the threaded bolts (16) with which the basin (18) is fixed to the base plate (24).
Popravki so mogoči z nastavitvijo treh samozapornih šestrobih matic (8) na navojnih sornikih (16), s katerimi je teme udarne glave (18) pritrjeno na osnovno ploščo (24).
The rubber rings (10) under the hexagon nuts (8) should not be brittle or cracked.
Obroči iz gume (10) pod šestrobimi maticami (8) ne smejo biti krhki ali razpokani.
The cover (19) of the impact surface and the intermediate ring (13) should always be replaced immediately if damaged, especially when the phantom head can no longer be adjusted.
Prevleko (19) udarne površine in vmesni obroč (13) je treba po poškodbi vedno takoj zamenjati, zlasti če nastavitev modela glave ni več mogoča.
Supporting fixture for testing flat test pieces is as described in paragraph 3.1.3.
Podporno ogrodje za preskušanje ravnih preskušancev je takšno, kot je opisano v odstavku 3.1.3.
Test conditions are specified in paragraph 3.1.4.
Preskusni pogoji so določeni v odstavku 3.1.4.
The pane shall be clamped to the supporting structure by means of appropriate devices.
Plošča se pritrdi na podporno napravo z ustreznimi napravami.
The surface of the pane shall be substantially perpendicular to the incident direction of the headform weight.

Starting from a selected initial drop height, the drop heights should be raised by 0,5 m respectively in each further experiment. The deceleration curves occurring on impact on the sample for ax, ay and az should be recorded according to time t.
Izbrano začetno višino pada je treba pri vsakem naslednjem preskusu zvišati za 0,5 m. Krivulje pojemka ob udarcu na vzorec za ax, ay in az je treba zabeležiti glede na čas t.
After the headform test, it should be checked whether a glazing edge has moved more than 2 mm in the mount and whether the requirement for the point of impact was met.
Po preskusu z modelom glave je treba preveriti, ali se je rob preskušane plošče v nosilcu premaknil za več kot 2 mm in ali je bila izpolnjena zahteva glede točke udarca.
The acceleration components ax and ay should be smaller for vertical impact than 0,1 az.
Vrednosti pospeškov ax in ay pri navpičnem udarcu morata biti manjši od 0,1 az.
The deceleration curves should be evaluated as follows:
Krivulje pojemka je treba vrednotiti na naslednji način:
The resulting deceleration ares(t) in the centre of gravity according to equation (1) from the measured deceleration curves ax(t), ay(t) and az(t) is to be compounded as multiples of the acceleration due to gravity.
Rezultirajoči pojemek ares(t) v težišču je treba določiti po enačbi (1) iz izmerjenih krivulj pojemka ax(t), ay(t) in az(t) ter izraziti kot večkratnik pospeškov zaradi sile težnosti.
The time for which a deceleration of 80 g with ares is continually exceeded and the greatest deceleration of ares should be determined.
Določiti je treba čas, v katerem pojemek ares stalno presega vrednost 80 g in največjo vrednost tega pojemka.
The HIC-value should be calculated as a measurement of the danger of blunt skull-brain-injuries using the following equation (2):
Vrednost HIC se izračuna kot merjenje nevarnosti tope poškodbe lobanje in možganov po naslednji enačbi (2):
The integral limits t1 and t2 should be selected in such a way that the integral takes a maximal value.
Meji integralov t1 in t2 je treba izbrati tako, da integral zajame največjo vrednost.
