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. 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 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 of 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 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.

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. 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 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 of 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 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.

Part 6:
Assembly power tools for threaded fasteners
1 Scope
This International Standard applies to hand-held non-electric power tools driven by rotary or linear motors,
powered by compressed air, hydraulic fluid or internal combustion engines and intended to be used by one
operator and supported by:
⎯ the operator's hand or hands or a suspension, e. g. a balancer.
⎯ hand-held tools which are intended to be capable of being fixtured.
Compliance with this standard on its own does not imply that power tools are suitable for use in potentially
explosive atmospheres, for which additional safety measures are likely to be required.
NOTE: EN 13463-1 gives requirements for non-electrical equipment for potentially explosive atmospheres.
This part, applies to hand-held, non-electric, power tools for tightening or installing of threaded fasteners. This
part lists the significant hazards caused by such power tools and specifies safety requirements valid for
different aspects of safety during their foreseeable lifetime.
Power tools covered by this part of the standard:
⎯ air-hydraulic impulse wrenches
⎯ impact wrenches
⎯ fastener installation tools
⎯ nut runners
⎯ open-ended spanners
⎯ ratchet wrenches
⎯ screwdrivers
