Supplement 1 - Jan 1997

Main body of the Regulation.

Electric Vehicles - Category A: Independent braking systemCategory B: Part of the Service braking system.

Annex 4 Tests with Electric Vehicles. 1.2.8. If wheel motors permanently connected, test like this. 1.2.9 and make a Type O test on low mu as behaviour test. 1.5.1.6 Possible to reduce heating cycle speed. 1.5.3.1.2 Cat A vehicles shall not use any separate control. 1.5.3.3 Hot test at max. speed. 2.2.6 Performance tests under faulty RGB conditions.
