The work of pre
9、paring 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
10、 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 2.The main task o
11、f technical committees is to prepare 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
12、 drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 236-2 was prepared by Technical Committee ISO/TC 29, Small tools, Subcommittee SC 2, High speed steel cutting
13、tools and their attachments.This second edition cancels and replaces the first edition (ISO 236-2:1976), of which it constitutes a minor revision. In particular, dimensions in inches (Imperial units) have been deleted, and an informative annex, giving the relationship between the symbols of this par
14、t of ISO 236 and the symbols according to ISO 13399 (all parts), has been added.ISO 236 consists of the following parts, under the general title Reamers: Part 1: Hand reamers1) Part 2: Long fluted machine reamers with Morse taper shanksIntroduction1) It is intended that, upon revision, the main elem
15、ent of the title of Part one will be aligned with the main element of the title of Part two.iv ISO 2013 All rights reservedBS ISO 236-2:2013INTERNATIONAL STANDARD ISO 236-2:2013(E)Reamers Part 2: Long fluted machine reamers with Morse taper shanks1 ScopeThis part of ISO 236 specifies the dimensions
