Users should note that all International Standards undergo revision from time to time and that any reference made herein to any other International Standard implies its latest edition, unless otherwise stated. e) Limit deviations have been extended fo r some tole rance classes used in fine mechanisms and horology, in basic sizes UP to 50 mm. d) Limit deviations have been extended for holes H and JS, for shafts h and js, by including tolerance grades IT17 and IT18 in all basic sizes, and, for experimental purposes only, by including tolerance grades IT1 to IT5 in basic sizes over 500 mm up to 3 150 mm. c) Limit deviations have been included for basic sizes from 500 to 3 150 mm as standard requirements (these were previously included on an experimental basis only). The letters s and S stand for symmetrical deviation. s and S are no longer placed as subscripts) to facilitate the use of the symbols on equipment with limited character sets, e.g. b) The new symbols js and JS replace the former symbols js and Js (i.e. This has been achieved by separating the material dealing with the bases of the system, and the calculated values of standard tolerances and fundamental deviations, from the tables giving specific limits of the most commonly used tolerances and deviations. The major changes incorporated in this part of IS0 286 are as follows:Ī) The presentation of the information has been modified so that IS0 286 can be used directly in both the design office and the workshop. ISO/R 286 was first published in 1962 and subsequently confirmed in November 1964 it was based on ISA Bulletin 25 first published in 1940.
This part of IS0 286 has been prepared by ISO/TC 3, Limits and fits, and, together with IS0 286-1, completes the revision of ISO/R 286, IS0 system of limits and fits. They are approved in accordance with IS0 procedures requiring at least 75 % approval by the member bodies voting. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the IS0 Council. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. The work of preparing International Standards is normally carried out through IS0 technical committees.
