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.
ISO 11148-6 was prepared by Technical Committee ISO/TC 118, Compressors and pneumatic tools, machines
and equipment, Subcommittee SC 3, Pneumatic tools and machines.
This second edition cancels and replaces the first edition (ISO 11148-6:2010), of which it constitutes a minor revision.
ISO 11148 consists of the following parts, under the general title Hand-held non-electric power tools — Safety

Introduction
This document is a type C standard as stated in ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
defined in the Scope of this part of ISO 11148.
When provisions of this type C standard are different from those that are stated in type A or B standards, the
requirements of this type C standard take precedence over the requirements of other standards for machines
that have been designed and built according to the requirements of this type C standard.
ISO 11148 consists of a number of independent parts for individual types of hand-held, non-electric power tools.
Certain elements of this part of ISO 11148 cover hand-held, non-electric power tools driven by internal
combustion engines powered by gaseous or liquid fuel. In these parts, the safety aspects relating to internal
combustion engines are found in a normative annex.
The parts are type C standards and refer to pertinent standards of types A and B where such standards are applicable.

This part of ISO 11148 covers
— air-hydraulic impulse wrenches;
— impact wrenches;
— fastener installation tools;
— nutrunners;
— open-ended spanners (crow-foot with open-ended socket or tube nut wrench);
— ratchet wrenches;
— screwdrivers.
NOTE 1 For examples of assembly power tools for threaded fasteners, see Annex B.
This part of ISO 11148 does not cover special requirements and modifications of assembly power tools for
threaded fasteners for the purpose of mounting them in fixtures.
This part of ISO 11148 deals with all significant hazards, hazardous situations or hazardous events when
the tools are used as intended and under conditions of misuse which are reasonably foreseeable by the
manufacturer, with the exception of the use of assembly power tools for threaded fasteners in potentially
explosive atmospheres.
NOTE 2 EN 13463-1 gives requirements for non-electrical equipment for potentially explosive atmospheres.

4 Safety requirements and/or protective measures
4.1 General
The machine shall comply with the following safety requirements and/or protective measures and be verified in
accordance with Clause 5. In addition, the machine shall be designed in accordance with the principles of ISO 12100
for the relevant, but not necessarily significant, hazards, which are not dealt with by this part of ISO 11148.
The measures adopted to comply with the requirements of Clause 4 shall take account of the state-of-the-art.
It is recognized that optimizing the design with respect to some safety measures can result in a degradation of
performance against other safety requirements. In such cases, it is required to strike a balance between the
various requirements in order to achieve an assembly power tool design that satisfies each requirement, so far
as is reasonably practicable, and remains fit for purpose.
4.2 Mechanical safety
4.2.1 Surfaces, edges and corners
Accessible parts of assembly power tools for threaded fasteners, except the inserted tool, shall not have sharp
edges or angles or rough or abrasive surfaces; see ISO 12100:2010, 6.2.2.1.
4.2.2 Supporting surface and stability
Assembly power tools for threaded fasteners shall be so designed that they can be laid aside and remain in a
stable position on a plane surface.
4.2.3 Hydraulic fluid ejection
Hydraulic systems of the assembly power tool shall be enclosed so as to give protection against high-pressure
fluid ejection.
4.2.4 Guards
Guards covering the drive adaptor and the inserted tool are not required.
4.2.5 Access openings
Openings provided in the assembly power tool for threaded fasteners to allow access to adjusting means shall
be designed to protect the operator from pinching his/her fingers while operating the tool; see ISO 13857.
4.2.6 Socket retainer
The socket retainer shall be designed and used so that it retains the socket on the output shaft while the
assembly power tool for threaded fasteners is operating. Loose pin retainers shall have a positive means of
retaining the pin.
4.2.7 Power tool construction
The assembly power tool for threaded fasteners shall be designed and constructed so as to prevent the
loosening or loss of components during expected use, including rough handling and occasional dropping,
which can compromise its safety functions. Verification shall be made in accor
