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 11148-4 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 11148-4:2010), 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
requirements:
— Part 1: Assembly power tools for non-threaded mechanical fasteners
— Part 2: Cutting-off and crimping power tools
— Part 3: Drills and tappers
— Part 4: Non-rotary percussive power tools
— Part 5: Rotary percussive drills

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.

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 a drill or tapper 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 non-rotary percussive power tools, 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
The non-rotary percussive power tool shall be designed such that it can be laid aside and remain in a stable
position on a plane surface.
4.2.3 Ejection of parts
Integral with or installed on a non-rotary percussive power tool shall be a retainer, without which the inserted
tool has the possibility of being ejected when it is operated off a work surface.
4.2.4 Hydraulic fluid ejection
Hydraulic systems of the non-rotary percussive power tools shall be enclosed so as to give protection against
high-pressure fluid ejection.
4.2.5 Guards
Guards covering the inserted tool are not required.
4.2.6 Power tool construction
The non-rotary percussive power tool shall be so designed and constructed as to prevent the loosening or loss
of components during expected use, including rough handling and occasional dropping, which can compromise
its safety functions.
4.3 Thermal safety
Surface temperatures of parts of the non-rotary percussive power tools that are held during use or that can be
inadvertently touched shall follow the provisions of ISO 13732-1 and ISO 13732-3.
Pneumatic tools shall be designed to avoid the cooling effects of exhaust air on the handles and other gripping zones.
4.4 Noise reduction
The non-rotary percussive power tool shall be designed and constructed so that the emission of noise is
reduced to the lowest level, taking account of technical progress and the availability of means of reducing
noise, in particular at source. Principles for designing non-rotary percussive power tools with reduced noise
emission are contained in ISO/TR 11688-1 and ISO/TR 11688-2.
The noise emission from using non-rotary percussive power tools has three main sources:
— the non-rotary percussive power tool itself;
— the inserted tool;
— the workpiece.
NOTE Generally, the noise emitted due to the characteristics of the workpiece cannot be controlled directly by the
manufacturer of the non-rotary percussive power tool.
Typical sources of noise emitted by the non-rotary percussive power tool itself are
a) the motor and drive mechanism;
b) the exhaust air or gases;
c) vibration- or impact-induced noise.
Where the exhaust air or gases are the major contributor to the noise, means to reduce the noise, for example
a silencer or equivalent means, shall be included in the design.

Alternatively, where practicable, the exhaust air or gases can be piped away from the operator in a hose.
Vibration-induced noise can often be reduced by vibration isolation and damping.
This list is not exhaustive; where alternative technical measures for noise reduction, with greater efficiency, are
available, they should be used by the manufacturer.
4.5 Vibration
The non-rotary percussive power tool shall be designed and constructed so that the vibration is reduced to the
lowest level at the handles, and at any other parts of the tool in contact with the operator’s hands, taking account
of technical progress and the availability of means of reducing vibration, in particular at the source. Principles
