CERTIFICATION PROCEDURE FOR THE DUMMY LOWER LEG AND FOOT

1.

UPPER FOOT IMPACT TEST

1.1.

1.2.

The objective of this test is to measure the response of the Hybrid III foot and ankle to well-defined, hard faced
pendulum impacts.

The complete Hybrid III lower leg assembly, left (86-5001-001 ) and right (86-5001-002), equipped with the
foot and ankle assembly, left (78051-614) and right (78051-615), shall be used, including the knee assembly.
The load cell simulator (78051-319 Rev A) shall be used to secure the knee assembly (78051-16 Rev B) to the
test fixture.

1.3.

Test procedure

1.3.1. Each leg assembly shall be maintained (soaked) for four hours prior to the test at a temperature of 22 °C ± 3 °C
and a relative humidity of 40 (± 30 %). The soak period shall not include the time required to reach steady state
conditions.

1.3.2. Clean the impact surface of the skin and also the impactor face with isopropyl alcohol or equivalent prior to the

test. Dust with talc.

1.3.3. Align the impactor accelerometer with its sensitive axis parallel to the direction of impact at contact with the

foot.

1.3.4. Mount the leg assembly to the fixture shown in Figure 1. The test fixture shall be rigidly secured to prevent
movement during impact. The centre line of the femur load cell simulator (78051-319) shall be vertical
(± 0,5°). Adjust the mount such that the line joining the knee clevis joint and the ankle attachment bolt is
horizontal (± 3°) with the heel resting on two sheets of a flat low friction (PTFE sheet) surface. Ensure that the
tibia flesh is located fully towards the knee end of the tibia. Adjust the ankle such that the plane of the
underside of the foot is vertical and perpendicular to the direction of impact (± 3°) and such that the mid
sagittal plane of the foot is aligned with the pendulum arm. Adjust the knee joint to 1,5 (± 0,5) g range before
each test. Adjust the ankle joint so that it is free and then tighten just sufficiently to keep the foot stable on the
PTFE sheet.

1.3.5. The rigid impactor comprises a horizontal cylinder diameter 50 (± 2) mm and a pendulum support arm
diameter 19 ± 1 mm (Figure 4). The cylinder has a mass of 1,25 (± 0,02) kg including instrumentation and any
part of the support arm within the cylinder. The pendulum arm has a mass of 285 (± 5) g. The mass of any
rotating part of the axle to which the support arm is attached should not be greater than 100 g. The length
between the central horizontal axis of the impactor cylinder and the axis of rotation of the whole pendulum
shall be 125 (± 1) mm. The impact cylinder is mounted with its longitudinal axis horizontal and perpendicular
to the direction of impact. The pendulum shall impact the underside of the foot, at a distance of 185 (± 2) mm
from the base of the heel resting on the rigid horizontal platform, so that the longitudinal centre line of the
pendulum arm falls within 1° of a vertical line at impact. The impactor shall be guided to exclude significant
lateral, vertical or rotational movement.

1.3.6. Allow a period of at least 30 minutes between successive tests on the same leg.

1.3.7. The data acquisition system, including transducers, shall conform to the specifications for CFC 600, as described

in Appendix 5 of this Annex.

1.4.

Performance specification
