H. CALCULATION OF VEHICLE TARGET TEST WEIGHT
(1) Calculate the Rated Cargo and Luggage Weight (RCLW) as follows and record
on Data Sheet No. 1:
RCLW = VCW – (68.04 kg x DSC)
VCW = the Vehicle Capacity Weight from the vehicle placard, also taking into
account any reduction in load capacity.
DSC = the Designated Seating Capacity as indicated on the vehicle placard.
FOR TRUCKS, MPV’s or BUSES - If the RCLW calculated above is greater
than 136 kg, use 136 kg as the RCLW.
(2) Weigh the fully-instrumented dummies to be used.
(3) Calculate the Test Vehicle Target Weight (TVTW) by summing the “As Delivered”
weight, the RCLW, and the weight of the fully instrumented ES-2re and SID-IIs
dummies:
TVTW = As Delivered Weight + RCLW + ES-2re weight + SID-IIs weight
Record the TVTW.
I. “FULLY LOADED” VEHICLE WEIGHT CONDITION
(1) With the vehicle in the “As Delivered” weight condition, load the vehicle with the
ballast equal to the RCLW placed in the luggage or load carrying/cargo area.
Center the load over the longitudinal centerline of the vehicle.
(2) Place the weight of the fully instrumented test dummies (with clothes and shoes)
in the appropriate front and rear outboard seating positions.
(3) Weight the vehicle at each wheel and add the weights together to determine the
“Fully Loaded” weight. Record the weight measurements on Data Sheet No. 1.
J. VEHICLE ATTITUDE AND CG MEASUREMENTS – “FULLY LOADED” WEIGHT
CONDITION
(1) Place the vehicle on a flat, level surface in the “Fully Loaded” weight condition.
(2) If the vehicle has an Auto-Leveling System, the ignition must be set to the “on”
position. If the vehicle is equipped with a self-adjusting hydraulic system, contact
the COTR for further guidance on attitude measurements.
(3) If the vehicle has been raised off of the ground to make weight measurements,
the vehicle should be rolled for at least 10 meters and left to settle for at least 10
minutes prior to moving to step (4).
(4) “Exercise” the vehicle’s suspension system by pushing down and pulling up on
each of the four corners of the vehicle at least 5 times in an interval not to exceed
40 seconds each. Allow the vehicle to settle for at least 10 minutes.
(5) Mark a reference point on the test vehicle’s body, directly above each wheel
opening.
(6) For each wheel well, measure the distance between the ground and each of the
reference points. Record each measurement on Data Sheet No. 1.
(7) Measure and record the vehicle CG aft of the front axle and left(+)/right(-) from
the longitudinal centerline on Data Sheet No. 1.
