7.3.3 Legs<br />
7.3.3.1 Remove the jacket from the dummy.<br />
7.3.3.2 With the lower leg at 90° to the upper leg, and the dummy in seated position, lift the upper leg<br />
assembly above horizontal. Adjust the femur back set screw so the upper leg is held<br />
suspended at 1g.<br />
7.3.3.3 Rotate the lower leg assembly so it is horizontal. Adjust the knee clevis bolt so the lower leg<br />
is held suspended at 1g.<br />
7.3.3.4 Adjust the ankle ball joint screw so the foot is held suspended at 1g. The ankle adjustment is<br />
not critical and is determined by individual feet.<br />
7.3.3.5 Repeat the procedure on the other leg and foot.<br />
7.4 BioRID Clothing<br />
7.4.1 The dummy should be dressed with two pairs of close-fitting, knee-length, spandex/lycra<br />
pants and two close-fitting, short-sleeved spandex shirts. The under layer of clothes should be<br />
worn with the shiny/smooth side of the fabric facing out and the over-clothes with the<br />
shiny/smooth side against the underclothes (i.e. dull side facing out). The dummies feet<br />
should be shod with size 11 (45 <strong>Euro</strong>pean or 279mm) Oxford-style, hard-soled, work shoes<br />
(e.g. MIL-S-13192P).<br />
7.5 BioRID Instrumentation<br />
7.5.1 The instrumentation required to perform the <strong>Euro</strong> <strong>NCAP</strong> evaluation is listed in Table 2. The<br />
T1 acceleration should be the average of right and left side accelerometer measurements. All<br />
instrumentation shall be calibrated before the test programme.<br />
7.5.2 The channel amplitude class (CAC) for each transducer shall be chosen to according to Table<br />
2. In order to retain sensitivity, CACs which are orders of magnitude greater than the<br />
minimum amplitude should not be used. A transducer shall be re-calibrated if it reaches its<br />
CAC during any test. All instrumentation shall be recalibrated after one year regardless of the<br />
number of tests for which it has been used. A list of instrumentation along with calibration<br />
dates shall be supplied as part of the test report.<br />
