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 EN 792 consists of a number of independent parts for individual types of hand-held non-electric power tools Other European 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 BS EN 792-8:2001+A1:2008 EN 792-8:2001+A1:2008 (E) Scope EN 792 applies to hand-held non-electric power tools driven by rotary or linear motors, powered by compressed air or hydraulic fluid and intended to be used by one operator and supported by: the operator's hand or hands, a suspension, e.g a balancer This part of EN 792 applies to hand-held non electric power tools intended for polishing and sanding with all types of movement e.g rotary, orbital and reciprocating, using coated abrasive products and bonnets of various soft materials and endless belts This part lists the significant hazards caused by such power tools and specifies safety requirements valid for different aspects of safety during their foreseeable lifetime Power tools covered by this part of the standard: belt sanders, orbital sanders, polishers, random orbital sanders, rotary sanders, straight line sanders Special requirements and modifications on a hand-held power tool for the purpose of mounting it in a fixture are not covered by this part NOTE At the

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 5.3.2 Generally, the manufacturer has no possibility of influencing the noise emitted by the processed workpiece 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 at pneumatic tools; vibration induced noise The noise from the exhaust of air is one major contributor of noise from pneumatic driven hand-held power tools A silencer, conforming to EN ISO 14163, of good design will reduce this noise The principles contained in EN ISO 11688-1 and EN ISO 11688-2 should be followed to reduce the noise emitted by the power tool NOTE The exhaust air can also be piped away in a hose away from the operator, however this method has limitations in practice To control the air borne noise emission caused by the radiation of structure borne noise, vibration insulation and additional damping close to the source can be applied The criterion for assessing the efficiency of noise reduction measures are the actual noise emission values from the machine in relation to other machines of the same family and not the nature of the reduction measures themselves 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 For power tools driven with compressed air the exhaust air shall be directed in such a way that it cannot cause a hazard to the operator and so that any secondary effects are minimized e.g blowing the dust and reflected air from the workpiece onto the operator 10 BS EN 792-8:2001+A1:2008 EN 792-8:2001+A1:2008 (E) 5.5.2 Dust It shall be possible to operate the power tool with a dust collecting device or to use a dust suppression device NOTE Because the risks arising from dust will depend on the materials being processed it is not possible to give technical requirements for collection and disposal of the dust in this standard 5.5.3 Lubricants Lubricants for power tools, specified by the manufacturer, shall not cause hazards to the operator or the environment 5.6 Ergonomics 5.6.1 Design of the handle The handle and other parts used for gripping the power tool shall be designed to ensure that the operator is able to grip the power tool correctly and to perform the expected work Handles shall suit the functional anatomy of the hand and the dimensions of the hands of the operator population See 3.6 of EN 292-2:1991 and EN 614-1 Power tools having a mass greater than kg (including the inserted tool) shall be capable of being supported by two hands whilst being lifted or operated The strength of a removable handle and the nature of fixing it shall be appropriate to the intended principal use 5.6.2 Control device The control device shall be adapted to the handle or to the part of the power tool being gripped by the operator so that it can be held comfortably in the run position For power tools which are normally used in operations of long duration the trigger force to keep the start device in the run position shall be small For further information on trigger forces for control devices see EN 894-3 5.6.3 Suspension device Provision shall be made, where appropriate, to enable the attachment to the power tool of a suspension device The fitting of a suspension device shall not introduce an additional hazard 5.7 Safety related measures and means 5.7.1 Start and stop device The power tools shall be equipped with a single control device to start or stop them It shall be arranged near the handle so that the operator can activate it without releasing the grip on the handles The start and stop device shall be so designed that the inserted tool ceases to be powered when the start and stop device is released Without manual effort it shall, when released, move to the stop position, i.e be of the type "hold to run" The start and stop device shall be in the stop position or immediately move to the stop position when the power tool is connected to the energy supply It shall not be possible to lock the start and stop device in the running position 11 BS EN 792-8:2001+A1:2008 EN 792-8:2001+A1:2008 (E) As an exception for orbital sanders with rectangular pads, delta sanders and straight-line sanders, the start and stop device may be designed to be locked in the on-position, provided it can easily be unlocked without relinquishing hold of the power tool 5.7.2 Unintentional start The start and stop device shall be so designed, positioned or guarded that the risk of unintentional start is minimized For rotary sanders with sanding discs having a diameter of 180 mm and more, the star and stop device shall be so designed that it requires two separate and dissimilar actions to start the power tool Verification shall be made according to 7.3 Information for use 6.1 Marking, signs and written warnings !Sanders and polishers shall be marked visibly, legibly and indelibly with the following minimum particulars:
