24、, Switzerland and United Kingdom. EN 792-8:2001+A1:2008 (E) 4 Introduction This European standard is a type C standard as stated in EN 1070:1998. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this standard. When pro
25、visions 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 79
26、2 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 trimm
27、ers; 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
28、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 powe
29、r 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 n
30、on-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
31、such standards are applicable. EN 792-8:2001+A1:2008 (E) 5 1 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 operators hand or hands, a suspension,
32、 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 signif
33、icant 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 sander
34、s. 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 date of publication no sanders and polishers driven by internal combustion engines are known. 2 Normative references This European Standard incorp
