Whiplash Testing Protocol - Euro NCAP

in and out of the head and has gradations to allow backset measurements to be taken. A similar height
probe slides horizontally from the top of the head and allows the height of a head restraint to be
measured.
When fitting the H-PM to the HRMD it should be noted that the H-PM must first be modified to
accept the unit. The height bar must be removed and its spacing on the spine spindle be replaced by
two washers. Four of the original 8 hanger weights are replaced by two larger cylindrical weights.
These allow the HRMD forks to locate onto the weight hanger.
2. Equipment Requirements
H-PM/HRMD Calibration Jig
The H-PM/HRMD unit is to be calibrated together as one single unit. The H-PM/HRMD unit is held
in a jig, known as GLORIA, which will facilitate calibration. The jig is equipped with feet at each
corner to facilitate levelling. The jig holds the seat pan by three horizontal bars of 20mm thickness
that support the seat pan allowing the thigh bar to be horizontal. The back pan is supported by 900mm
vertical bar with its origin at the base of the seat pan in the area of the buttock. This vertical support
has a horizontal bar at the level of the weight hanger bar and is level. A cord is attached to the back
pan to prevent the H-PM falling forward. Near the top of the vertical support are scribed markings to
indicate the target position of the HRMD height probe. This vertical support allows the calibration of
the backset probe when extended.
