This International Standard specifies the method of testing the air or air over hydraulic braking systems of vehicles of categories M and N (excluding M1 and N1) as defined in Annex 7 to the UN-ECE Consolidated Resolution on the Construction of Vehicles (R.E.3.) which are built to comply with UN-ECE Regulation 13/09 including supplements 1-6. Test methods covering lock actuators or the electrical regenerative braking systems of electric and hybrid vehicles are not included in this edition.
NOTE Requirements of UN-ECE Regulation 13 related purely to the design of braking systems and braking system components are not part of this International Standard.
The values in square brackets [ ] and the values in tables are taken from UN-ECE Regulation No. 13.
