The work of preparing International Standards is norm

9、ally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in t

10、he work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare

11、 International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some

12、 of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 12366 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 23, Mopeds. Annex A of this International Stan

14、ped with one or more antilock, and one or more independent, braking systems. Its purpose is to establish uniform worldwide test procedures for such systems. This International Standard sets out procedures for the following types of straight-line braking tests: utilization-of-adhesion test; wheel-loc

15、k check test; tests with ABS failed; complementary tests that could assist in the assessment and development of braking systems. NOTE Reference is made in this International Standard to L-category vehicles, generally referring to solo mopeds (L1), drawn from Regulation No. 78 and the Consolidated Re

16、solution on the Construction of Vehicles (R.E.3) of the United Nations Economic Commission for Europe (UN-ECE). The values given in this International Standard enclosed by square brackets are from the same regulation (02 series of amendments), and are included for information. 2 Normative references

The test surface shall be substantially level (i.e. it shall not contain a gradient exceeding 1 %) and shall be free of extraneous materials. For wetted su

30、rfaces, inconsistent results can occur due to aquaplaning or varying brake performance. Therefore, water depth should not exceed 3 mm.
