F1ANNEX XIIInertia dynamometer test method for brake linings
2.TEST EQUIPMENT
2.1.
A dynamometer having the following characteristics shall be used:
2.1.1.
it shall be capable of generating the inertia required by point 3.1 of this Annex, and have the capacity to meet the requirements prescribed by points 1.3, 1.4 and 1.6 of Annex II with respect to Type I, Type II and Type III fade tests;
2.1.2.
the test brakes fitted shall be identical with those of the original vehicle-type concerned;
2.1.3.
air cooling, if provided, shall be in accordance with point 3.4 of this Annex;
2.1.4.
the instrumentation for the test shall be capable of providing at least the following data:
2.1.4.1.
a continuous recording of disc or drum rotational speed;
2.1.4.2.
number of revolutions completed during a stop, to resolution not greater than one eighth of a revolution;
2.1.4.3.
stop time;
2.1.4.4.
a continuous recording of the temperature measured in the centre of the path swept by the lining or a mid-thickness of the disc or drum or lining;
2.1.4.5.
a continuous recording of brake application control line pressure or force;
2.1.4.6.
a continuous recording of brake output torque.
