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

Certain parts of EN 792 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 European Standards of type A and B where such
standards are applicable.

5 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.

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 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 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 Materials and substances processed, used or exhausted
5.5.1 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 e
