The work of preparing International Standards is normally carried out
11、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 coll
12、aborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approv
13、al criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the sub
14、ject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trad

17、tion (ISO 464:1995), of which it constitutes a technical revision with the following changes: implementation of Geometrical Product Specifications (GPS); different presentation of the tables.iv ISO 2015 All rights reservedBS ISO 464:2015ISO 464:2015(E)IntroductionThis International Standard is a mac
18、hine element geometry standard as defined in the geometrical product specification (GPS) system as presented in the matrix model of ISO 146387.The fundamental rules of ISO/GPS given in ISO 80153 apply to this International Standard and the default decision rules given in ISO 14253-15apply to the spe
19、cifications made in accordance with this International Standard, unless otherwise indicated.The connection between functional requirements, measuring technique and measuring uncertainty is always intended to be considered. The traditionally used measuring technique is described in ISO 1132-22. For m
20、easurement uncertainty it is intended that ISO 14253-26should be considered.For small radial bearings, when D 30 mm, manufacturing a snap ring groove might distort the raceways. As such, it is recommended to use bearings with a flanged outer ring instead. Information about snap ring grooves and snap
21、 rings for these small bearings can be found in Annexes A and B.Annexes C and D contain informative information on snap ring material and an example of correct application.Annex E contains an example of a real drawing indication of a snap ring groove.
