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



EN 792-11:2000+A1:2008 (E) 5 1 Scope The standard EN 792 applies to hand-held non-electric power tools driven by rotary or linear motors, powered by compressed air, 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, EN 792-11, applies to hand-held, non-electric power tools with a reciprocating movement for nibbling and shearing. 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:  nibblers,  shears. 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 power tools driven by internal combustion engines are known. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of the publications referred to in this European Standard are valid only when they are incorporated in this standard by amendment or revision. For undated references the latest edition of the publication referred to, applies (including amendments).

The hand-held power tool is operated by one or two hands NOTE Hand-held power tools driven by compressed air or gas are called pneumatic tools. Hand-held power tools driven by hydraulic liquid are called hydraulic tools. 3.1.2 inserted tool tool inserted in the hand-held power tool to perform the intended work 3.1.3 service tool tool intended for performing maintenance or service on the hand-held power tool 3.1.4 control device device to start and stop the hand-held power tool or to change the direction of the rotation or to control the functional characteristics such as speed and power 3.1.5 maximum operating pressure maximum pressure that a hand-held power tool may be operated at, as specified by the manufacturer 3.2 Definitions related to nibblers and shears 3.2.1 nibbler power tool for punching sheet formed material where material removal is caused by a reciprocating motion of a punch through a fixed die 3.2.2 shear power tool used for shearing sheet formed material with a cutter in a reciprocating motion relative to fixed a cutter by a shearing action.
