Certification of the Lumbar Spine
General
The lumbar spine test is a component test, which is performed using a pendulum as
defined in CFR49 part 572. To certify the Q3 lumbar spine, remove it from the dummy.

The lumbar spine is attached upside down to this pendulum. A head form is used to
load the lumbar spine. This head form consists of two flat disks connected by an
interface, which allows certification of both the neck and the lumbar spine. The head
form rotation during the test is measured using two rotational potentiometers. One is
installed on the base of the neck-pendulum interface the second one is attached to the
head form. Both potentiometers are linked with a thin shaft (see 23 right and 24 right).
The sum of the two angles measured on the potentiometers is the angle of the head
relative to the pendulum.
The data acquisition system and all instrumentation must comply with the requirements
of SAE J211, version March 1995. All data channels should be filtered using a hardware
filter prior to A/D conversion according to SAE J211, version March 1995.
The pendulum acceleration should be measured with an accelerometer which is located
on the pendulum arm, 1657.4 mm from the pendulum pivot in accordance with the CFR
49 Part 572.
