indicated in the scope of this standard.
When provisions of this type C standard are different from those which are stated in type A or B standards, the
provisions of this type C standard take precedence over the provisions of other standards, for machines that
have been designed and built according to the provisions of this type C standard.
The European Standard, EN 792, consists of a number of independent parts for individual types of hand-held
non-electric power tools.
Other EN 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

Safety requirements and measures

5.1

Mechanical safety

5.1.1

Surfaces, edges and corners

Accessible parts of the power tools shall not have sharp edges or angles or rough or abrasive surfaces, see
3.1 of EN 292-2:1991.
5.1.2

Supporting surface and stability

Power tools shall be so designed that they can be laid aside and remain in stable position on a plane surface.
5.1.3

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 power tool by design, e.g. clip, but not by a chain or
string or other similar means.
5.1.4

High pressure ejection

Hydraulic systems of the power tools shall be enclosed so as to give protection against high pressure fluid
ejection.
5.1.5

Guards

Guards covering the chuck and inserted tools are not required.

5.2

Thermal safety

Surface temperatures of parts of the power tools which are held during use or could be inadvertently touched
shall follow the provisions of EN 563.
NOTE

The limit values for low temperatures are studied by CEN/C 122.

Power tools for use in potentially explosive atmospheres should comply with EN 1127-1. However because
the suitability of a power tool for use in potentially explosive atmospheres will depend not only on the power
tool but the inserted tool and the workpiece, it is not possible to give any detailed advice in this standard.

5.3

Noise

5.3.1

General

The emission of noise from a hand-held power tool shall be kept as low as possible.
The noise emission from using hand-held power tools emanates from three main sources:


the hand-held power tool itself,



the inserted tool,



the workpiece.

NOTE

Generally, the manufacturer has no possibility of influencing the noise emitted by the processed workpiece.

9


BS EN 792-3:2000+A1:2008

EN 792-3:2000+A1:2008 (E)

5.3.2

Noise emitted by the hand-held power tool

The noise emitted by the hand-held power tool itself can be divided into:


noise from the motor,



noise from exhaust air at pneumatic tools,



vibration induced noise.

The noise from the exhaust of air is one major contributor of noise from pneumatic driven hand-held power
tools. A silencer of good design will reduce this noise.
The principles contained in EN ISO 11688-1 should be followed to reduce the noise emitted by the power tool.
NOTE
The exhaust air can also be piped away in a hose away from the operator, however this method has
limitations in practice.

Vibration induced noise can be reduced by use of acoustic isolation and vibration damping.

5.4

Vibration

Vibration at the handle of a hand-held power tool shall be kept as low as possible. The principles contained in
CR 1030-1 should be followed to reduce the vibration emitted by the power tool.

5.5
5.5.1

Materials and substances processed, used or exhausted
Exhaust air

For power tools driven with compressed air the exhaust air shall be directed in such a way that it cannot cause
a hazard to the operator and so that any secondary effects are minimized. e.g. blowing the dust and reflected

air from the workpiece onto the operator.
5.5.2

Dust

It shall be possible to connect to drills a dust collecting device or to use a dust suppression device.
5.5.3

Lubricants

Lubricants for power tools, specified by the manufacturer, shall not cause hazards to the operator or the
environment.

5.6
5.6.1

Ergonomics
Design of the handle

Handles and other parts used for gripping the power tool shall be designed to ensure that the operator is able
to grip the drill or the tapper correctly and to perform the expected work. Handles shall suit the functional
anatomy of the hand and the dimensions of the hands of the operator population. See 3.6 of EN 292-2:1991
and EN 614-1.
Power tools having a mass greater than 2 kg (including the inserted tool) shall be capable of being supported
by two hands whilst being lifted or operated.

10


BS EN 792-3:2000+A1:2008

EN 792-3:2000+A1:2008 (E)

5.6.2

Control device

The control device shall be adapted to the handle or to the part of the power tool being gripped by the
operator so that it can be held comfortably in the run position.
For power tools which are normally are started frequently and often used for precision works the trigger force
should be small.
For further information on trigger forces for control devices see EN 894-3:2000.
5.6.3

Suspension device

Provision shall be made, where appropriate, to enable the attachment to the power tool of a suspension
device. The fitting of a suspension device shall not introduce an additional hazard.
5.6.4

Reaction torque

Drills and tappers shall be designed so that the effect of reaction torque is reduced as much as possible. This
can be done by mounting a support handle or other suitable means.
There shall be provisions for mounting a support handle when the chuck capacity is equal or larger than 16
mm.
Straight rotary tools shall have provisions for mounting a second handle, when the reaction torque is over
4 Nm.
Pistol grip tools shall have a provision for mounting a second handle, when the reaction torque is over 10 Nm.

5.7
5.7.1

Safety related measures and means
Start and stop device

Drills and tappers shall be equipped with a single control device to start or stop them. It shall be arranged near
the handle so that the operator can activate it without releasing the grip on the handles.
The start and stop device shall be so designed that the inserted tool ceases to be powered when the start and
stop device is released. Without manual effort it shall, when released, move to the stop position, i.e. be of the
type "hold to run".
The start and stop device shall be in the stop position or immediately move to the stop position when the drill
or tapper is connected to the energy supply.
It shall not be possible to lock the start and stop device in the running position.
5.7.2

Unintentional start

The start and stop device for drills and tappers with chuck capacity larger than 10 mm shall be so designed,
positioned or guarded that the risk of unintentional start is minimized. Verification shall be made according to
7.3.

11


BS EN 792-3:2000+A1:2008

EN 792-3:2000+A1:2008 (E)

!Relationship between this European Standard and the Essential
Requirements of EU Directive 98/37/EC

This European Standard has been prepared under a mandate given to CEN by the European Commission
and the European Free Trade Association to provide a means of conforming to Essential Requirements of the
New Approach Directive 98/37/EC, amended by 98/79/EC on machinery.
Once this standard is cited in the Official Journal of the European Communities under that Directive and has
been implemented as a national standard in at least one Member State, compliance with the clauses of this
standard confers, within the limits of the scope of this standard, a presumption of conformity with the
corresponding Essential Requirements of that Directive except ER 1.5.7 and associated EFTA regulations.
WARNING - Other requirements and other EU Directives may be applicable to the product(s) falling within the
scope of this standard."
