25、anization 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 technical committee has been establi
26、shed 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 matters of electrotechnical standardizatio
27、n.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 circulated to the member bodies for voting. Pu
28、blication 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.

29、 rights.ISO 11148-7 was prepared by Technical Committee ISO/TC 118, Compressors and pneumatic tools, machines and equipment, Subcommittee SC 3, Pneumatic tools and machines.

33、 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 of independent parts for individual types of hand-h
34、eld 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 found in a normative annex.The parts are type-C sta
35、ndards and refer to pertinent standards of type A and B where such standards are applicable.

37、ety requirements for hand-held non-electric power tools (hereinafter “grinders”) intended for grinding and cutting-off with abrasive products, for use on all kinds of materials. The grinders can be powered by compressed air or hydraulic fluid and are intended to be used by one operator and supported
38、 by the operators hand or hands, with or without a suspension, e.g. a balancer.NOTE 1 At the time of publication, no grinders driven by internal combustion engines are known (other than cutting-off machines within the scope of ISO 19432). Once these are identified, it is intended to amend this part
39、of ISO 11148 to include such power tools.This part of ISO 11148 is applicable to grinders used with: abrasive products with a peripheral operating speed less than or equal to 80 m/s; cutting-off wheels with a peripheral operating speed less than or equal to 100 m/s; abrasive products with an outside
40、 nominal diameter less than or equal to 230 mm; cutting-off wheels with an outside nominal diameter less than or equal to 250 mm; wire brushes; diamond and reinforced (segmented) wheels with an outside nominal diameter less than or equal to 450 mm; flap discs and flap wheels.NOTE 2 For examples of g
41、rinders, see Annex B.NOTE 3 Typical abrasive products used together with hand-held grinders are listed in Annex D.This part of ISO 11148 does not cover special requirements and modifications of grinders for the purpose of mounting them in fixtures.This part of ISO 11148 is not applicable to: die gri
42、nders with collets, which are treated in ISO 11148-9; polishers and sanders (i.e. tools used with coated abrasives except flap discs and flap wheels), which are treated in ISO 11148-8; cutting-off machines which are driven by internal combustion engines and are used for cutting construction material
