This standard has been prepared by Technical Committee ISO/TC 195 “Building construction machinery and equipment” in collaboration with Technical Committee CEN/TC

6、 151 “Construction equipment and building material machines Safety” (Secretariat: DIN. Germany). The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-13-36 AA Handgehaltene Maschinen und Au

7、srstungen of Section Bau- und Baustoffmaschinen. Representatives of manufacturers and users of hand-held machinery and equipment, and of the contributed to this standard. This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directi

8、ve 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 is cited in the Official Journal of the European Union, i

9、t 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 and taken over as European Standards have been published

10、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 standard differs from DIN EN ISO 19432:2010-01 as follows: a) th

11、e Foreword has been supplemented; b) Clause 1 “Scope” has been modified; c) Clause 2 “Normative references” has been updated; d) Clause 3 “Terms and definitions” has been revised and new definitions have been included; e) Clause 4 “Safety requirements and verification” and Clause 5 “Information for

32、d as stated in ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are covered are indicated in the Scope of this International Standard. When requirements of this type-C standard are different from those which are stated in type-A or -B stand

33、ards, the requirements of this type-C standard take precedence over the requirements of the other standards for machines that have been designed and built according to the requirements of this type-C standard. EN ISO 19432:2012 (E) DIN EN ISO 19432:2012-12 4 1 Scope This International Standard speci

34、fies safety requirements, and measures for their verification, for the design and construction of portable, hand-held, internal combustion engine-driven, cut-off machines, intended to be used by a single operator in the cutting of construction materials, such as asphalt, concrete, stone and metal. I

35、t is applicable only to those machines designed purposely for use with a rotating, bonded-abrasive and/or super-abrasive (diamond) cut-off wheel having a maximum outer diameter of 430 mm, centre-mounted on, and driven by, a spindle shaft, where the top of the wheel rotates away from the operator (se

36、e Figure 1). This International Standard deals with all significant hazards, hazardous situations or hazardous events significant to these machines when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. (See Annex F for a list of significa

37、nt hazards.) This International Standard specifies methods for the elimination or reduction of hazards arising from their use, as well as the type of information on safe working practices to be provided with the machines. Cut-off wheel specifications are not considered in this International Standard

38、; for such specifications, see, for example, ISO 603-71, ISO 1394212and ISO 2291715. This International Standard is not applicable to machines manufactured before the date of its publication. 2 Normative references The following referenced documents are indispensable for the application of this docu
