Price based on 12 pages Copyright Intermational Organization for Standardization without license from IHS Not for Resale Foreword ISo (the International Organization for Standardization) is a worldwide federation of national standards bodies (iSO member bodies). The work of preparing International Standards is normally carried out through Iso technical committees. Every member body interested in a subject for which a technical committee has been established has mental and non-governmental, in liaison with iso, also take part in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by least 75 % approval by the member bodies voting. International Standard ISO 3002/4 was prepared by Technical Committee ISO/TC 29, Smalltools.

It should be read in conjunction with iso 3002/1 which is more general. 3.2 total torque exerted by the tool M: The entire torque produced by the cutting action of a tool around a specified axis. It is generally applicable to all machining operations, including grinding.
