A summary of worldwide passenger car braking regulations reveals that two standards are being increasingly adopted: the USA Federal Standard 105-75 and the EEC Directive 71/320 (equivalent to ECE Regulation 13).
Recent amendments of these two important regulations are critically reviewed, with special emphasis on the European vehicle stability and adhesion utilization prescriptions.
Supplementary comparisons between the USA and European braking regulations include analyses of the corresponding test procedures, which may benefit the harmonization studies initiated by the ECE government experts in Geneva.
