each femur of the dummy and measured according to Paragraph 5.2.4. of Annex 3.
5. PROCEDURE FOR CALCULATING THE VISCOUS CRITERIA (V * C) FOR HYBRID III
5.1. The viscous criterion is calculated as the instantaneous product of the compression and the
rate of deflection of the sternum. Both are derived from the measurement of sternum deflection.
5.2. The sternum deflection response is filtered once at CFC 180. The compression at time t is
calculated from this filtered signal as:
where constant = 0.229 for the HIII 50
and constant = 0.187 for the HIII 5
C(t) = D(t) / constant,
The sternum deflection velocity at time t is calculated from the filtered deflection as:

signal. The calibration of the data channel shall cover the whole range of the amplitude
For bi-directional channels, both the positive and negative values shall be used.

Measurement of V , V , V
3 ASSESSMENT PROCEDURE FOR LOW ELECTRICAL ENERGY
Prior to the impact a switch S and a known discharge resistor R is connected in parallel to the
relevant capacitance (ref. Figure 2 below).
Not earlier than 5s and not later than 60s after the impact the switch S shall be closed while the
voltage V and the current I are measured and recorded. The product of the voltage V and the
current I shall be integrated over the period of time, starting from the moment when the switch S
is closed (t ) until the voltage V falls below the high voltage threshold of 60 V DC (t ). The
resulting integration equals the total energy (TE) in Joules.
(a) TE = ∫ V × I dt
When V is measured at a point in time between 5s and 60s after the impact and the capacitance
of the X-capacitors (C ) is specified by the manufacturer, total energy (TE) shall be calculated
according to the following formula:
(b) TE = 0.5 × C × (V – 3,600)
When V and V (see Figure 1 above) are measured at a point in time between 5s and 60s after
the impact and the capacitances of the Y-capacitors (C , C ) are specified by the manufacturer,
total energy (TE , TE ) shall be calculated according to the following formulas:
(c) TE = 0.5 × C × (V -3,600)
TE = 0.5 × C × (V – 3,600)
This procedure is not applicable if the test is performed under the condition where the electric
power train is not energized.
4.1. Acceptance Conditions
The requirements of Paragraph 220.127.116.11.3. of this Regulation shall be considered to be met if the
jointed test finger described in figure 1 of Appendix 1, is unable to contact high voltage live parts.
If necessary a mirror or a fiberscope may be used in order to inspect whether the jointed test finger
touches the high voltage buses.
If this requirement is verified by a signal circuit between the jointed test finger and high voltage live
parts, the lamp shall not light.
5. ISOLATION RESISTANCE
The isolation resistance between the high voltage bus and the electrical chassis may be
demonstrated either by measurement or by a combination of measurement and calculation.
The following instructions should be used if the isolation resistance is demonstrated by
Measure and record the voltage (V ) between the negative and the positive side of the high
voltage bus (see Figure 1 above);
Measure and record the voltage (V ) between the negative side of the high voltage bus and the
electrical chassis (see Figure 1 above);
Measure and record the voltage (V ) between the positive side of the high voltage bus and the
electrical chassis (see Figure 1 above);
If V is greater than or equal to V , insert a standard known resistance (R ) between the negative
side of the high voltage bus and the electrical chassis. With R installed, measure the voltage (V ’)
between the negative side of the high voltage bus and the vehicle electrical chassis (see Figure 3
below). Calculate the isolation resistance (R ) according to the formula shown below.
R = R *(V /V ’ – V /V ) or R = R *V *(1/V ’ – 1/V )
Divide the result R , which is the electrical isolation resistance value in Ohm (Ω), by the working
voltage of the high voltage bus in Volt (V).
R (Ω/V) = R (Ω)/Working voltage (V)
Measurement of V ’
Note: The standard known resistance R (in Ω) should be the value of the minimum required
isolation resistance (Ω/V) multiplied by the working voltage (V) of the vehicle plus/minus 20%. R is
not required to be precisely this value since the equations are valid for any R ; however, a R
value in this range should provide a good resolution for the voltage measurements.
6. ELECTROLYTE SPILLAGE
Appropriate coating shall be applied, if necessary, to the physical protection in order to confirm any
electrolyte leakage from the REESS after the impact test.
Unless the manufacturer provides means to differentiate between the leakage of different liquids,
all liquid leakage shall be considered as the electrolyte.
7. REESS RETENTION
Compliance shall be determined by visual inspection.
