5、des safety requirements. This standard has been prepared by Technical Committee ISO/TC 118 “Compressors and pneumatic tools, machines and equipment” in collaboration with Technical Committee CEN/TC 255 “Hand-held, non-electric power tools Safety” (Secretariat: SIS, Sweden). The responsible German bo
6、dy involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-08-13 AA Druckluftwerkzeuge und -maschinen of Section Kompressoren und Drucklufttechnik. This standard contains specifications meeting the essential requirements
7、 set out in Annex I of the “Machinery Directive”, Directive 2006/42/EC, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of that directive. Once this standard
8、is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The International Standards referred to in this document
9、and taken over as European Standards have been published as the corresponding DIN EN ISO Standards with the same number. Where the International Standards and documents referred to are not also DIN ISO Standards with the same number, there are no national standards available. Amendments This standar
10、d differs from DIN EN 792-7:2009-12 as follows: a) the text of ISO 11148-7:2012 has been adopted in its entirety; b) technical requirements of ANSI B.186.1 and references to EN ISO 12100 have been incorporated; c) vibration total values and their uncertainties are to be declared; d) user instruction
11、s shall include further and more detailed safety instructions; e) the former Annex E has been incorporated in the new specifications relating to wheels in Subclause 4.2.9. This is only an editorial change which has been done for reasons of simplification and better legibility; f) at least 180 (inste
12、ad of 175) of the wheel shall be covered by the guard; g) requirements for guards to be used for abrasive products type 6 (coated with diamonds or boron nitride) have been included; h) in Subclause 5.5 “Test of guards”, it has been specified that burst tests for guards are mandatory for all types of
13、 wheels, except for superabrasive wheels.

30、2 (E) IntroductionThis 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 are different from those which
31、 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 of independent parts for indiv
32、idual 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 found in a normative annex.The
33、 parts are type-C standards and refer to pertinent standards of type A and B where such standards are applicable.4DIN EN ISO 11148-7:2013-01EN ISO 11148-7:2012 (E) IMPORTANT The colours represented in the electronic file of this document can be neither viewed on screen nor printed as true representa
34、tions. For the purposes of colour matching, see ISO 3864-4, which provides colorimetric and photometric properties together with, as a guideline, references from colour order systems.1 ScopeThis part of ISO 11148 specifies safety requirements for hand-held non-electric power tools (hereinafter “grin
35、ders”) 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 by the operators hand or hands, with or without a suspension, e.g. a bala
36、ncer.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 of ISO 11148 to include such power tools.This part of ISO 11148 is applica
37、ble 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 nominal diameter less than or equal to 230 mm; cutting-off wheels with an
38、 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 grinders, see Annex B.NOTE 3 Typical abrasive products used together with h
39、and-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 grinders with collets, which are treated in ISO 11148-9; polishers and sander
40、s (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 materials, which are treated in ISO 19432; shaft-mounted wire brushes, which are t
41、reated in ISO 11148-9.5DIN EN ISO 11148-7:2013-01 EN ISO 11148-7:2012 (E) This part of ISO 11148 deals with all significant hazards, hazardous situations or hazardous events relevant to grinders when they are used as intended and under conditions of misuse which are reasonably foreseeable by the man
42、ufacturer, with the exception of the use of grinders in potentially explosive atmospheres.NOTE 4 EN 13463-1 gives requirements for non-electrical equipment for potentially explosive atmospheres.2 Normative referencesThe following referenced documents are indispensable for the application of this doc
