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
13、dard is for information only.INTERNATIONAL STANDARD ISO 12366:2001(E) ISO 2001 All rights reserved 1 Two-wheeled mopeds Antilock braking systems (ABS) Tests and measurement methods 1 Scope This International Standard specifies tests and measurement methods for solo mopeds (defined in ISO 3833) equip
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
17、 The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this Int
18、ernational Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.

29、in this International Standard: one with a coefficient of adhesion not exceeding 0,45; one with a coefficient of adhesion of not less than 0,80. 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. NOTE It is recognized that certain surface parameters are not well defined and that sound engineering judgement is needed to ensure the proper surface. 4.2 Wind spee

In the interests of repeatability, it is
43、recommended that “rapidly applied” be given to mean within a time of 0,2 s to 0,5 s to reach the prescribed, or full, force. This is the maximum force prescribed in ISO 8709:1995, 8.3, and for vehicle category L1: 200 N for hand controls, 350 N for foot controls. A higher force may be used if requir

48、 of the test lane immediately before passing the point at which the test is to commence. The rider shall then keep the drive disengaged for the remainder of the test. 6.9.2.2 For mopeds with a fully automatic transmission, the rider shall fully close the throttle and enter the centre of the lane imm
