Inertia shall be determined by the calculation equation specified in Item 7 of JIS DO210
(Calculation Equation).
procedures and test equipment such as dual or single dynamometers.
1)
2)
vehicle load (dual dynamometer) divided by the ratio of the front and rear wheel braking forces at
a braking deceleration of 4.5 m/s2
Test loads, however, shall be as follows to accommodate specific test
Front-and-rear combination tests using a dual dynamometer: 1/2 of the total vehicle load
Right-left combination tests: 1/2 of the total vehicle load (single dynamometer) or total
4.3 Temperature Measurement
A thermocouple shall be installed on the fixed side as specified in Item 6 (Temperature Measurement) of
JIS D0210, as a rule.
Remarks:
4.4. Cooling Wind
Cooling wind shall be at room temperature, shall be applied at a velocity of 11 m/s, as a rule, and shall be
directed to blow uniformly and continuously against the projected surface of the brake device.
Remarks:
4.5 Temperature Adjustment
When adjustments are required to achieve a specified initial brake temperature refer to Item 5.2.d Burnish
conditions.
