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. Esch 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.
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

Introduction
Portable and fixed pneumatic tools used primarily for driving threaded
fasteners are often produced with electronie devices for monitoring and
control. Until now, there has been no International Standard giving guid-
ante to manufacturers on a uniform means of connection of pneumatic
tools and electronie equipment.
Contributions and comments solicited from manufacturers and users of
both pneumatic tools and electronie equipment have lead to the prep-
aration of this International Standard which is intended to promote the in-
terchangeability of tools and equipment to the mutual benefit of
manufacturers and users.
