24、dForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a
25、technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matter
26、s of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulat
27、ed to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible
28、 for identifying any or all such patent rights. ISO 11148-11 was prepared by Technical Committee ISO/TC 118, Compressors and pneumatic tools, machines and equipment, Subcommittee SC 3, Pneumatic tools and machines. ISO 11148 consists of the following parts, under the general title Hand-held non-elec
29、tric power tools Safety requirements: Part 1: Assembly power tools for non-threaded mechanical fasteners Part 2: Cutting-off and crimping power tools Part 3: Drills and tappers Part 4: Non-rotary percussive power tools Part 5: Rotary percussive drills Part 6: Assembly power tools for threaded fasten

31、) ISO 2011 All rights reserved vIntroduction This document is a type-C standard as stated in ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are defined in the Scope of this part of ISO 11148. When requirements of this type-C standard a
32、re different from those which are stated in type-A or -B standards, the requirements of this type-C standard take precedence over the requirements of other standards, for machines that have been designed and built according to the requirements of this type-C standard. ISO 11148 consists of a number
33、of independent parts for individual types of hand-held non-electric power tools. Certain parts of ISO 11148 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
34、 found in a normative annex. The parts are type-C standards and refer to pertinent standards of type A and B where such standards are applicable.

35、 Safety requirements Part 11: Nibblers and shears IMPORTANT The colours represented in the electronic file of this document can be neither viewed on screen nor printed as true representations. For the purposes of colour matching, see ISO 3864-4, which provides colorimetric and photometric properties
36、 together with, as a guideline, references from colour order systems. 1 Scope This part of ISO 11148 specifies safety requirements for hand-held non-electric power tools (hereinafter “nibblers and shears”) with a reciprocating movement for nibbling and shearing. The nibblers and shears can be powere
37、d by compressed air or hydraulic fluid and are intended to be used by one operator and supported by the operators hand or hands, with or without a suspension, e.g. a balancer. NOTE 1 At the time of publication, no nibblers and shears driven by internal combustion engines are known. Once these are id
38、entified, it is intended to amend this part of ISO 11148 to include such power tools. This part of ISO 11148 is applicable to: nibblers; shears. NOTE 2 For examples of nibblers and shears, see Annex B. This part of ISO 11148 is not applicable to special requirements and modifications of nibblers and
39、 shears for the purpose of mounting them in a fixture. This part of ISO 11148 deals with all significant hazards, hazardous situations or hazardous events relevant to nibblers and shears when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacture
40、r, with the exception of the use of nibblers and shears in potentially explosive atmospheres. NOTE 3 EN 13463-1 gives requirements for non-electrical equipment for potentially explosive atmospheres. 2 Normative references The following referenced documents are indispensable for the application of th

46、hands and driven by rotary or linear motors powered by compressed air, hydraulic fluid, gaseous or liquid fuel, electricity or stored energy (e.g. by a spring) to do mechanical work and so designed that the motor and the mechanism form an assembly that can easily be brought to its place of operation
47、 NOTE Hand-held power tools driven by compressed air or gas are called pneumatic tools (or air tools). Hand-held power tools driven by hydraulic liquid are called hydraulic tools. 3.1.2 inserted tool tool inserted in the nibbler or shear to perform the intended work 3.1.3 service tool tool intended
