1 Scope
This standard is applicable to fastener driving tools which are handled by one person and in which energy in a
linear movement is applied to a loaded fastener for the purpose of driving this into a workpiece of a
determined material. During the driving operation, the fastener leaves the tool partially or entirely, with
sufficient velocity to overcome the resistance of penetration, and forms a mechanical connection or
attachment of different workpieces. The energy required for driving a fastener is provided by compressed air
or combustible gases.
NOTE 1 Fastener driving tools are also referred to for example as Nailers, Staplers, Tackers, Pinners.
NOTE 2 The workpiece material can, for example, consist of wood, wooden materials, plastic material, fibre materials -
loose or condensed, cement- and lime materials, metal.
This standard contains requirements for the design, marking and information for use of fastener driving tools,
corresponding to the specific hazards listed in clause 4. The standard sets out the means of verification for
these requirements.
Where, for clarity, an example of a safety measure is given in the text, this shall not be considered as the only
possible solution. Any other solution leading to the same risk reduction is permissible if an equivalent level of
safety is achieved.
This standard is applicable to fastener driving tools which have been produced after the date of publication of
the standard.
This standard is not applicable to stapling pliers and vibration hammers.
NOTE 3 "Stapling pliers" are handheld power operated tools equipped with a fixed or moving anvil bar in front of the
muzzle, which are used predominantly for joining paper, leather, textiles and similar materials.
This standard is not applicable to fastener driving tools in which the energy for driving fasteners is drawn from
cartridges or from any type of electric supply.

3 Definitions
The following definitions are applicable for the purpose of this standard:
3.1
fastener driving tool
a handheld power tool in which energy is applied in a linear movement to a loaded fastener for the purpose of
driving the latter into defined materials. During the driving operation, the fastener leaves the tool partially or
completely. The tool may be fitted with a single-, sequential-, contact- or continuous release system and
operated in accordance therewith. The energy required for driving operation is drawn from compressed air,
combustible gases, or any other source whose energy can be stored inside the fastener driving tool and
released as required
3.2
fastener
the concept "fastener" comprises nails, staples, pins, corrugated fasteners, screws used as nails, dowels,
sleeves, bushes, cable collars and base supports
3.3
collating material
material for joining together single fasteners in strips or coils with e.g. lacquer, paper or plastic tape, plastic
strap or wire
3.4
trigger
component part of the fastener driving tool used to supply energy to the driving mechanism

3.5
safety yoke
mechanism with a workpiece contact element in the muzzle area which prevents the tool from driving a
fastener if it is not pressed against the workpiece (See figure 1)
3.6 actuating systems
3.6.1 Actuating systems on fastener driving tools with a safety yoke
3.6.1.1
single sequential actuation
an actuating system in which the trigger and the safety yoke have to be operated so that only one single
driving operation is actuated via the trigger after the muzzle of the tool has been applied to the driving
location. Thereafter further driving operations can only be performed after the trigger has been returned to the
non driving position whilst the safety yoke remains depressed
3.6.1.2
full sequential actuation
an actuating system in which the trigger and the safety yoke have to be interconnected so that only one single
driving operation is actuated via the trigger after the muzzle of the tool has been applied to the driving
location. Thereafter further driving operations can only be performed if the trigger and the safety yoke have
first been returned to the non driving position
3.6.1.3
contact actuation
an actuating system in which the trigger and the safety yoke have to be actuated for each driving operation,
with the order of actuation not being specified. For repeated driving operations, it is sufficient that either the
trigger remains activated and the safety yoke is activated thereafter, or vice versa
3.6.1.4
continuous contact actuation
an actuating system in which the trigger and the safety yoke have to be actuated, with the order of actuation
not being specified. The driving operations continue as long as the trigger and the safety yoke remain
actuated
3.6.2 Actuating systems on fastener driving tools without safety yoke
3.6.2.1
single actuation
an actuating system in which the trigger has to be actuated for each driving operation
3.6.2.2
continuous actuation
an actuating system in which the driving operations are carried out for as long as the trigger remains actuated
3.7
dispenser for combustible gas
non-reusable container made of metal, glass or plastic and containing a combustible gas compressed or
liquefied and fitted with a release device allowing the content to be ejected
NOTE Dispenser for combustible gas are also referred to for example as aerosol dispenser, flammable gas container
or gas cartridge.

Figure 3 — Example for protection covers by the magazine (sectional view)
5.1.2 Protection against ejected fasteners
5.1.2.1 Connection to the energy supply system
Fastener driving tools designed for connection to a energy supply system shall be equipped in such a way that
they
can be easily connected to and disconnected from the energy supply system using a quick-action
coupling,
cannot self actuate a driving operation on connection to the energy supply system,
do not retain any energy for a driving operation following disconnection from the energy supply system.
NOTE Because user of compressed air operated fastener driving tools can already possess a quick release system,
the type of connecting nipple (see 3.8 item 10) can be delivered by choice of the manufacturer and can not necessary be
fitted to the tool.
The quick-action-connector (see 3.8 item 14) is not constituent of delivery.
Dispensers for combustible gas and batteries for the ignition system on fastener driving tools operated by
internal combustion must be capable of connection and disconnection without the need of service tools.
5.1.2.2 Prevention against accidental trigger actuation
The design of fastener driving tools and the placement of the trigger shall be such as to prevent unintentional
actuation when the tool is placed on or moved across a surface, for example the work-surface.
NOTE The trigger normally is fitted in the inner area of the handle contour of the fastener driving tool (see figure 2).

EN 792-13:2000+A1:2008 (E)
5.1.3 Protection against free flight of fasteners at high velocity
Fastener driving tools shall be fitted with a safety yoke which acts independently of the trigger and which is
functionally safe. This safety yoke shall ensure that no driving operation can be performed before the muzzle
of the tool is pressed to the workpiece.
A safety yoke is not required on fastener driving tools which accelerate the heaviest usable fasteners to a free
flight velocity vl below the corresponding admissible 5,0 mm depth of penetration x into human muscular
im pen
tissue. See annex A (normative).
5.1.4 Design of the safety yoke
To minimise the possibility of a free flying fastener occurrence by accidentally touching the workpiece with the
edge or corner of the safety yoke and therefore placing the muzzle outside the workpiece surface, the external
dimensions of the safety yoke should not be greater than
l = 18 mm for fastener driving tools with
contact actuation;
continuous contact actuation;
full sequential actuation using fasteners of a driving length of more than 130 mm.
l = 30 mm for fastener driving tools with
single sequential actuation;
full sequential actuation using fasteners of a driving length of 130 mm or below (see figure 4).

5.1.5 Design of fastener driving tools with safety yoke
5.1.5.1 Fastener driving tools with a safety yoke must be designed in such a way that the safety yoke does
not actuate the trigger system when the tool is set down.
5.1.5.2 Depending on the length of usable fastener in the fastener driving tool, only fastener / tool
combinations with an actuating system as given in table 1 are permitted.

5.3.2.2 The incidental release of gas from combustion powered fastener driving tools shall not cause iced
areas to form on the handles.
5.4 Noise
Measures to reduce noise produced by fastener driving tools include for example reducing the generation of
noise and constructing the fasteners in such a way that noise is reduced by damping, and in the case of
compressed air operated fastener driving tools by fitting an exhaust air damper. See EN ISO 11688-1.
NOTE In many cases in addition to the noise produced by a fastener driving tools in use, the noise generation at the
point of action is influenced by the working operation itself and cannot be reduced by tool design. The noise at the point of
action can for example depend on the working environment, the workpiece, the workpiece support, the number of driving
operations, in the case of compressed air operated fastener driving tools and with regard to the desired use; on optimum
regulation of the working pressure.
5.5 Mechanical impact (vibration)
The effect of mechanical impacts (vibration) transmitted to the hand-arm system should be kept to a minimum
during operation of fastener driving tools.
NOTE Factors of influence are constituted
in the design of fastener driving tools by
weight,
driving velocity;
in the handling process by
pressing effort,
hand gripping force depending on working direction,
adjustment of the energy supply (avoidance of excessive energy);
in the case of the workpiece by
workpiece material (density, strength),
workpiece support.
In the case of aperiodic impacts transmitted to the hand-arm system, these factors may exert a mutual
influence on each other.
5.6 Protection against chips, discharged air or waste gases
5.6.1 Collating residues
Fastener driving tools shall be designed in such a way that collation residues do not cause harm.
5.6.2 Discharged air or waste gases
Discharged air or waste gases produced by the operation of fastener driving tools must be directed so that the
user of the tool is not subjected to discomfort, either directly or indirectly, for example as a result of dust being
raised from the workpiece. This can for example be realised by an adjustable deflector.

5.7 Ergonomics
5.7.1 For the proper balance of fastener driving tools see EN 614-1, 4.1.4 and following.
5.7.2 To ensure the handling of fastener driving tools is in accordance with ergonomic principles, the space
between the handle and the magazine must be sufficient to accommodate the fingers. In cases where
experience has shown that fastener driving tools are used outdoors, for example on building sites, or for
processing rough materials such as unplanned timber, consideration must be given to the fact that the user
should be able to use the tool whilst wearing work gloves (see annex C).
5.7.3 The trigger shall be designed and fitted in such a way that it can be operated with the right or the left
hand.
5.7.4 It must be possible to fit fastener driving tools over 2,5 kg total weight with a hanger (see clause 3.8
item 6).
5.7.5 Fastener driving tools weighting more than 6 kg shall be supplied with a second handle which can be
fitted by the user.
5.8 User information
5.8.1 The marking of a fastener driving tool must be in accordance with 7.1 - Marking.
5.8.2 The operating instructions for a fastener driving tool must be in accordance with 7.2 - Operating
instructions.
5.9 Protection against fire and explosion
5.9.1 The operating instructions for compressed air operated fastener driving tools must warn against the
use of
oxygen by reason of explosive reaction with lubricants inside the tool,
flammable gases by giving rise to an explosive atmosphere around the tool.
5.9.2 The operating instructions for internal combustion operated fastener driving tools must warn again
