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.

SIST EN ISO 11148-3:2011
ISO 11148-3:2010(E)
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 relevant, but not necessarily significant, hazards, which are 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 the drills and tappers 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 drill or tapper shall be so designed that it can be laid aside and remain in a stable position on a plane
surface.
4.2.3 Chuck keys and service tools
Chuck keys and service tools used with drilling and tapping chucks shall be so designed that they drop easily
out of position when released. They may be fixed to the drill or tapper by design, e.g. clip, but not by a chain
or string or other similar means. The avoidance of entanglement should be considered; see 6.2.2.5.
4.2.4 Hydraulic fluid ejection
Hydraulic systems of the drills and tappers shall be enclosed so as to give protection against high-pressure
fluid ejection.
4.2.5 Guards
Guards covering the chuck and the inserted tools are not required.
4.2.6 Spindles
4.2.6.1 Spindle threads
When threaded spindles are used, the thread direction shall be such that the chuck or attachment shall tend to
tighten during tool operation, or a means shall be provided to secure the chuck.
4.2.6.2 Reversible tools
Spindles for reversible tools shall be designed to drive the chuck in both directions without loosening the
chuck and mounting. If a threaded spindle is used, a means shall be provided to secure the chuck.

SIST EN ISO 11148-3:2011
ISO 11148-3:2010(E)
4.2.7 Power tool construction
The drill or tapper 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. Verification shall be made in accordance with 5.5.
4.3 Thermal safety
Surface temperatures of parts of the drills and tappers 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
The drill or tapper 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 the
source. Principles for designing drills and tappers with reduced noise emission are contained in
ISO/TR 11688-1 and ISO/TR 11688-2.
The noise emission from using drills and tappers has three main sources:

NOTE 1 Generally, the noise emitted due to the characteristics of the workpiece cannot be controlled directly by the
manufacturer of the drill or tapper.
Typical sources of noise emitted by the drill or tapper itself are
a) the motor and drive mechanism;
b) the exhaust air or gases;
c) the 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.

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 11148-3 was prepared by Technical Committee ISO/TC 118, Compressors and pneumatic tools,
machines and equipment, Subcommittee SC 3, Pneumatic tools and machines.
ISO 11148 consists of the following parts, under the general title Hand-held non-electronic power tools –

have been designed and built according to the provisions of this type C standard.
The Standard consists of a number of independent parts for individual types of hand-held non-electric power
tools.
Other standards deal with safety rules for hand-held power tools used in e. g. the following fields:
⎯ agriculture and forestry such as chain saws, hedge-trimmers, brush cutters, grass trimmers
⎯ construction and building such as cutting-off power tools, concrete vibrators
⎯ food industry, such as fowl secateurs, sheep shears.
Endeavours have been made to achieve co-ordination with the relevant Technical Committees so that the
safety requirements are compatible.
This standard is divided in the following parts:
Part 1 - Assembly power tools for non-threaded mechanical fasteners (former part 14)
Part 2 - Cutting-off and crimping power tools (former part 15)
Part 3 - Drills and tappers

Drills and tappers
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 used for rotary drilling of holes in all kinds of material,
e.g. wood, metal, concrete, plastics etc. and tappers for tapping and cleaning threads in metal and plastics.
This part lists the significant hazards caused by drills and tappers and specifies safety requirements valid for
different aspects of safety during their foreseeable lifetime.
Power tools covered by this part of the standard:
⎯ drills
⎯ heavy duty drills with two handles
⎯ tappers.
For examples of drills and tappers see annex A.
Special requirements and modifications on drills or tappers for the purpose of mounting it in a fixture are not
covered by this part.
NOTE: At the date of publication no drills and tappers driven by internal combustion engines are known. When these are
identified the standard will be amended to include such powered tools.
