All technical contents of this standard are mandatory. This standard is developed in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 24545-2009 Requirement of speed limitation system for motor vehicles. The following main changes have been made with respect to GB/T 24545-2009 (the previous edition): ——the nature of this standard is changed from voluntary into mandatory; ——the name of this standard is changed to Requirements and test methods of speed limitation system for motor vehicles; ——the "Scope" is modified (see Clause 1); ——the “Normative references” is modified (see Clause 2); ——the “Terms and definitions” is modified (see Clause 3); ——the “General requirements” is modified (see Clause 4); ——the requirements for vehicles with the maximum speed limitation system are modified (see Clause 5); ——the requirements for vehicles with adjustable speed limitation system are modified (see Clause 6); ——Annex A is changed to Clause 7, "Test methods for vehicles with maximum speed limitation system", and some contents are modified (see Clause 7); ——Annex B is changed to Clause 8 "Test methods for vehicles with adjustable speed limitation system", and some contents are modified (see Clause 8). The technical contents of this standard refer to the European Union directive UN Regulation No.89 Uniform provisions concerning speed limitation. This standard was proposed by and is under the jurisdiction of the Ministry of Industry and Information Technology of the People's Republic of China. The previous edition of this standard is as follows: ——GB/T 24545-2009.
