EN 792-11:2000+A1:2008 (E) 4 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 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. SIST EN 792-11:2000+A1:2008
