4.4.3
VEHICLE WEIGHTS.
The vehicle shall be weighed to determine curb weight and distribution of curb weight on
front and rear axle. The imposed loading on front and rear axle shall be computed using
the curb weight and the payload as specified in 3.5 through 3.5.6. Calculated imposed
loads on front and rear axle shall be utilized to ascertain that suspension, axles, and tires
furnished are of adequate capacity to meet contract requirements.
4.4.3.1 WEIGHT DISTRIBUTION TOLERANCE.
The mathematical method to calculate the weight distribution shall be in accordance with
AMD Standard 013.
a.
Find the curb weight on each wheel of a given axle;
b.
Divide the weight of each wheel by the total curb weight of both wheels (i.e., curb
weight of the axle), times (X) 100 = percentage of weight on each side;
c.
Subtract the smaller percentage from the larger percentage;
d.
This is the percent difference between the left and right side of the axle. If this
difference is 5 percent or less, that particular axle's weight distribution has met the
provisions of 3.5.4.
4.4.4
ROAD TEST.
The vehicle shall be subjected to a minimum 241 km (150 mile) road test of which 121 km
(75 miles) shall be continuous miles on paved highways at highway speeds up to 113 km/
hr (70 mph); 48 km (30 miles) on city streets; 24 km (15 miles) on gravel or dirt roads at
speeds up to at least 56 km/hr (35 mph); and not less than 8 km (5 miles) in simulated or
actual cross-country operation at speeds applicable to the terrain. Cross-country operation
is defined as travel over open fields, rolling and side-sloping hills, rough and muddy terrain.
Class 2 vehicles shall demonstrate cross-country operation in 4-wheel drive for an additional
32 km (20 miles). Ambulances shall meet performance requirements specified in 3.4.4
through 3.4.10 during road tests or by certification. Balance of the 241 km (150 miles)
road test may be accumulated during other tests and checks requiring vehicle movements.
After completion of the road test, vehicle shall be subjected to the water spray test (see
4.4.5). Road test may be performed at any ambient temperature.
4.4.4.1 TEST FAILURE OF FIRST AMBULANCE.
Vehicle utilized for the road test shall successfully complete 241 km (150 miles) of test.
Rejection of the test vehicle shall be for deficiencies, including but not limited to the
following:
a.
Damage caused by collision.
b.
Failure of any major component.
c.
Vibration due to misalignment of wheels, frame, driveshaft, or defective tires, etc.
