Introduction
This European standard is a type C standard as stated in EN 1070.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
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
Part 4 - Non rotary percussive power tools
Part 5 - Rotary, percussive power drills
Part 6 - Assembly power tools for threaded fasteners
Part 7 - Grinders
Part 8 - Sanders and polishers
Part 9 - Die grinders
Part 10 - Compression power tools
Part 11 - Nibblers and shears
Part 12 - Small circular, small oscillating and reciprocating saws
Part 13 - Fastener driving tools

Scope

The standard EN 792 applies to hand-held non-electric power tools driven by rotary or linear motors, powered
by compressed air, hydraulic fluid and intended to be used by one operator and supported by:


the operator's hand or hands,



a harness,



a suspension, e.g. a balancer.

This part, EN 792-5, applies to hand-held, non electric, power tools used for making holes in hard materials
like rock and concrete. 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:


plug hole drills,



rock drills,



rotary hammers.

Special requirements and modifications on a hand-held power tool for the purpose of mounting it in a fixture
are not covered by this part.
For those power tools which are driven by an internal combustion engine the particular safety requirements
related to the engine are dealt with in annex C.

Safety requirements and measures

5.1

Mechanical safety

5.1.1

Surfaces, edges and corners

Accessible parts of rotary percussive drills, except the inserted tool, 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

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

Ejection of parts

Rotary percussive drills shall be equipped with a retainer or other device to prevent the ejection or falling out
of the inserted tool.
5.1.4

High pressure ejection

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

5.1.5

Guards

Guards covering the inserted tools are not required to be fitted to a rotary percussive drill.

5.2

Thermal safety

Surface temperatures of parts of the power tool which are held during use or could be inadvertently touched
shall follow the provisions of EN 563.
NOTE 1

The limit values for low temperatures are studied by CEN/TC 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 792-5:2000+A1:2008
EN 792-5:2000+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 or gases at pneumatic tools,



vibration induced noise.

The noise from the exhaust of air and gases is one major contributor of noise from pneumatic driven handheld 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 or gases 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 dampening.

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 or gas

For rotary percussive drills driven with compressed air or gas or by an internal combustion engine the exhaust
air or gases 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 or gas from the workpiece onto the
operator.
5.5.2

Dust

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

Lubricants

Lubricants for rotary percussive drills, 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 rotary percussive drill shall be designed to ensure that the
operator is able to grip the rotary percussive drill 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 792-5:2000+A1:2008
EN 792-5:2000+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 rotary percussive drills which are normally used in operations of long duration the trigger force to keep the
start device in the run position 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 rotary percussive drill of a
suspension device. The fitting of a suspension device shall not introduce an additional hazard.
5.6.4

Reaction torque

Rotary percussive drills 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.
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

Rotary percussive drills 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
rotary percussive drill is connected to the energy supply.
It shall not be possible to lock the start and stop device in the running position.
Rock drills may have a start and stop device that can be locked-on.
NOTE

The lock-on control offers collaring with less exposure to noise, vibration and dust.

For power tools driven by an internal combustion engine, see C.3.5.
5.7.2

Unintentional start

The start and stop device shall be so designed, positioned or guarded that the risk of unintentional start is
minimized.
Verification shall be made according to clause 7.3.
