Introduction

This standard has been drawn up to serve as a harmonised standard which represents one means of achieving conformity with the fundamental safety requirements of the EC Machinery Directive and associated EFTA Regulations

The extent to which hazards are covered is indicated in the scope of this standard In addition, machinery should comply as appropriate with EN 292 for hazards which are not covered by this standard

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

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

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 vlim below the corresponding admissible 5,0 mm depth of penetration xpen into human muscular 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;

on noise emission in accordance with EN 12549:1999 and EN ISO 4871

NOTE 1 These values are tool-related characteristic values and do not represent the noise generation at the point of use Noise at the point of use will for example depend on the working environment, the workpiece, the workpiece support, and the number of driving operations

In addition reference should be made to noise reduction measures

NOTE 2 Workplace design can also serve to reduce noise levels, for example placing workpieces on sound-damping supports (see also EN ISO 11690-1)

!The operator's instruction shall give information on airborne noise emissions:

 the A-weighted emission sound pressure level at workstations, where this exceeds 70 dB (A); where this level does not exceed 70 dB (A), this fact shall be indicated;

 the peak C-weighted instantaneous sound pressure value at workstations, where this value exceeds

63 Pa (130 dB in relation to 20 µPa);

 the A-weighted sound power level emitted by the machinery, where the A-weighted emission sound pressure level at workstations exceeds 80 dB(A)."

7.2.3 Information on mechanical impact (vibration)

The operating instructions and the technical literature determined for sales of fastener driving tools shall contain information on mechanical impact (vibration) in accordance with ISO 8662-11:1999 and EN 12096

If the vibration value exceeds 2,5 m/s² the value shall be declared

Where the vibration value does not exceed 2,5 m/s², this must be mentioned

NOTE This value is a tool-related characteristic value and does not represent the influence to the hand-arm-system when using the tool Any influence to the hand-arm-system when using the tool will for example depend on the gripping force, the contact pressure force, the working direction, the adjustment of energy supply, the workpiece, the workpiece support

!The operator's instruction shall give information on vibration total value in the handles, including uncertainty of measurement."

7.2.4 Additional instructions for fastener driving tools operated by compressed air

In addition to references identified in 7.2 to 7.2.2, the operating instructions for fastener driving tools operated

by compressed air shall make reference to the following:

a) fastener driving tools operated by compressed air shall only be connected to compressed air lines where the maximum allowable pressure cannot be exceeded by a factor of more than 10%, which can for example be achieved by a pressure reduction valve which includes a downstream safety valve;

b) when using fastener driving tools operated by compressed air, particular attention must be paid to avoid exceeding the maximum allowable pressure;

c) fastener driving tools operated by compressed air should only be operated at the lowest pressure required for the work process at hand, in order to prevent unnecessarily high noise levels, increased wear and resulting failures;

d) hazards caused by fire and explosion when using oxygen or combustible gases for operating compressed air operated fastener driving tools

7.2.5 Additional instructions for fastener driving tools operated by internal combustion

In addition to references identified in 7.2 up to 7.2.2, the operating instructions for fastener driving tools operated by internal combustion shall also make reference to the following:

a) fastener driving tools operated by internal combustion shall only be used with dispensers for combustible gas which are listed in the operating instructions;

b) fastener driving tools operated by internal combustion shall not be used in enclosed or poorly ventilated spaces;

c) in the case that liquid combustible gas comes into contact with human skin, injuries may occur;
