La norme européenne EN 792 s'applique aux machines portatives non électriques entraînées par des moteurs
rotatifs ou linéaires, alimentés par air comprimé, fluide hydraulique et prévues pour être utilisées par un seul
opérateur et portée par :
— la (ou les) main(s) de l'opérateur ;
— en suspension, par exemple à l'aide d'un équilibreur.
Cette partie, EN 792-3, s'applique aux machines portatives non électriques utilisées pour le perçage de trous par
rotation dans toutes sortes de matériaux (par exemple métal, bois, béton, matière plastique) et aux taraudeuses
utilisées pour tarauder et nettoyer des trous filetés dans le métal et dans le plastique.
Cette partie énumère les risques significatifs provoqués par de telles machines portatives et spécifie les prescriptions
de sécurité relatives aux différents aspects de sécurité pouvant être rencontrés pendant leur durée de vie.
La présente norme couvre les types de machines portatives suivantes :
- perceuses ;
- perceuses à deux poignées pour travaux lourds ;
- taraudeuses ;
Les modifications et prescriptions spécifiques en vue du montage d'une machine portative sur un support ne sont pas
traitées par la présente norme.
NOTE À la date de publication, il n'y a pas de perceuses et de taraudeuses mues par un moteur à combustion interne
connues.

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

For the purposes of this part of the standard, the following terms and definitions apply:
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
rotary power tool
hand-held power tool the machine spindle of which rotates
3.1.3
inserted tool
tool inserted in the hand-held power tool to perform the intended work
3.1.4
service tool
tool intended for performing maintenance or service on the hand-held power tool
