The work of preparing International Standards is normally 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 the 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. 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. International Standard ISO 13486-1 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 2, Braking systems and equipment. ISO 13486 consists of the following parts, under the general title Road vehicles Hydraulic braking systems: Part 1: Double-flare pipes, tapped holes, male fittings and tube seats Part 2: Flare-to-flare connections -,-,- -,-,- INTERNATIONAL STANDARD © ISOISO 13486-1:1999(E) 1 Road vehicles Hydraulic braking systems Part 1: Double-flare pipes, tapped holes, male fittings and tube seats 1 Scope This part of ISO 13486 specifies the essential dimensional and physical characteristics for double flares of metallic pipes (with and without surface protection), tapped holes, male fittings, and driving fit seats used in hydraulic braking systems for road vehicles. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 13486. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 13486 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.
