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

3.1 General terms and definitions
3.1.1 hand-held power tool: Machine driven by rotary or linear motors powered by compressed air, hydraulic
fluid, gaseous or liquid fuel, electricity or stored energy (e.g. by a spring) to do mechanical work and so
designed that the motor and the mechanism form an assembly that can easily be brought to its place of
operation. The hand-held power tool is operated by one or two hands.
NOTE Hand-held power tools driven by compressed air or gas are called pneumatic tools. Hand-held power tools
driven by hydraulic liquid are called hydraulic tools.
3.1.2 inserted tool: Tool inserted in the power tool to perform the intended work.
3.1.3 service tool: Tool intended for performing maintenance or service on the power tool.
3.1.4 control device: Device to start and stop the power tool or to change the direction of the rotation or to
control the functional characteristics such as speed and power.

5 Safety requirements and measures
5.1 Mechanical safety
5.1.1 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 3.1 of EN 292-2:1991.
5.1.2 Supporting surface and stability
Non-rotary percussive power tools 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
Non-rotary percussive power tools shall be equipped with a retainer to prevent ejection or falling out of the
inserted tool.
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.
5.2 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/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.
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,

SIST EN 792-4:2000+A1:2008
EN 792-4:2000+A1:2008 (E)
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 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 Materials and substances processed, used or exhausted
5.5.1 Exhaust air or gas
For non-rotary percussive power tools 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 i
