Tests for Manual
RESNA WC-01 or ISO 7176-01 Static Stability
stability on a slope in forward, rearward and side facing positions. The chair is placed on a platform that can be inclined.
A test dummy is placed in the chair. The ramp is gradually raised until the chair becomes unstable. The angle at which instability
occurs is recorded. The test is performed with the chair facing uphill, downhill and sideways.
RESNA WC-05 or ISO 7176-05 Dimensions, Mass and Turning Space
and folded dimensions of chair, mass of chair, and the distance needed to make a complete 180-degree turnaround.
RESNA WC-07 or ISO 7176-07 Seating Dimension
A list of
27 different dimensions are measured and recorded. Dimensions are taken with a RLG (Reference Loader Gage) in the seat. The
RLG has surfaces that allow consistent measurements to be taken.
WC-08 or ISO 7176-08 Static, Impact, and Fatigue Strength Testing
Static - Tests all structural parts for
strength (Pass/Fail Criteria). Parts of the wheelchair are subjected to loads from pneumatic cylinders.
– Tests structure for impact resistance (Pass/Fail Criteria). Parts of the wheelchair are subjected to impacts from
a weighted pendulum.
Fatigue –The double drum is a set of rollers that the wheelchair rides on for an extended
period of time. There are slats on the drums that simulate pavement irregularities. The Curb drop simulates the wheelchair
descending a curb. Both of these tests are conducted with a test dummy in the chair.
RESNA WC-15 or ISO 7176-15 Information Disclosure, Documentation, and Labeling
if all necessary safety and manufacturer’s labels appear on the chair
Aditional Tests for Powered Wheelchairs
RESNA WC-02 or ISO 7176-02 Dynamic Stability
This set of tests determines the ability of the chair to remain stable while moving.
Testing is conducted on various slopes to determine stability while starting, stopping and turning.
RESNA WC-03 or ISO 7176-03 Effectiveness of Brakes
the ability of the brakes to hold on a slope. The chair is placed on a platform that can be inclined. A test dummy is placed
in the chair. The platform is inclined until the wheels begin to slide on the surface, or the chair becomes unstable. The
angle at which the slip occurs is recorded.
RESNA WC-04 or ISO 7176-04 Determination
of Energy Consumption of electric Wheelchairs and Scooters- Theoretical Range
This test determines a theoretical
range for the battery set. The batteries are charged and a meter is attached to the battery. This meter reads battery capacity.
The tested device is driven on a test track in a clockwise direction for 10 laps and then a counterclockwise direction for
ten laps. The remaining battery charge is determined and the difference is calculated. The theoretical range based on the
listed capacity of the battery is then determined.
RESNA WC-06 or ISO 7176-06 Determination of Maximum Speed,
Acceleration and Retardation of Electric Wheelchairs
In this test the unit runs through a speed trap to determine
the maximum speed of the unit. Accelerometers are used to determine the maximum retardation of the unit. Retardation
is the ability of the chair to use the motors as dynamic brakes in emergency stop situations by commanding the joystick in
the opposite direction of travel.
RESNA WC-09 or ISO 7176-09 Climatic
Tests for Electric Wheelchairs
This test determines the ability of the power and control systems to operate
properly in adverse conditions of heat and cold. The tested device is subjected to extremes of heat and cold and then operated
on a test track to determine any unsatisfactory behavior.
RESNA WC-10 or ISO 7176-10 Determination of Obstacle
Tests the chair for its ability to climb obstacles in both a forward and rearward direction. The chair
is subjected to obstacles of increasing height until a maximum height is attained.
RESNA WC-14 or ISO 7176-14 Power and Control Systems for Electric Wheelchairs
Tests all electrical
systems including the battery and charger for safety and reliability. This includes all connectors, wiring labels, operating
control hardware and any other electrical system on the chair.
