The work of
26、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 established has the right to be represented on that committee. International organizations, governmental and non-governmental,
27、 in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main t
28、ask of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attent
29、ion 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 for identifying any or all such patent rights. ISO 19432 was prepared by Technical Committee ISO/TC 195, Building construction machinery and equipment. Th

31、gth (4.10); additional requirements for transmission cover (4.12); clarification of the parts to be recognized as hot parts, including temperature limits (4.13.1); additional requirement for electromagnetic immunity; added requirement for declaration of uncertainties to noise and vibration values (5

33、 position (C.5); inclusion of a simulated feeding force to the vibration test procedure (C.8); definition of machine positions (Annex D); additional information on reproducibility for noise and vibration measurements (Annex E); a new informative Annex F covering a list of significant hazards.

The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are covered are indicated in the Scope of this Interna
35、tional Standard. When requirements of this type-C standard are 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 the other standards for machines that have been designed and built according to the requir
36、ements of this type-C standard. BS EN ISO 19432:2012 ISO 19432:2012(E) BS EN ISO 19432:2012INTERNATIONAL STANDARD ISO 19432:2012(E) ISO 2012 All rights reserved 1Building construction machinery and equipment Portable, hand-held, internal combustion engine driven cut-off machines Safety requirements
37、1 Scope This International Standard specifies 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
38、 as asphalt, concrete, stone and metal. It 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
39、 wheel rotates away from the operator (see 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 manufactu
40、rer. (See Annex F for a list of significant 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
41、considered in this International Standard; 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 indis
