26、ing permitted without license from IHS-,-,-BS EN ISO 11806-2:2011ForewordISO (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 co
27、mmittees. 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, in liaison with ISO, also take part in the work. ISO collaborates closely with th
28、e 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 task of technical committees is to prepare International Standards. Draft Internation
29、al 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.Attention is drawn to the possibility that some of the elements of this document may be the
30、 subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 11806-2 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 17, Manually portable forest machinery.This first edition of ISO
31、11806-2 cancels and replaces ISO 14865:1998 and ISO 14740:1998.ISO 11806 consists of the following parts, under the general title Agricultural and forestry machinery Safety requirements and testing for portable, hand-held, powered brush-cutters and grass-trimmers: Part 1: Machines fitted with an int

37、ck-pack power unit1 ScopeThis part of ISO 11806 gives safety requirements and measures for their verification for the design and construction of portable, hand-held, powered brush-cutters and grass-trimmers with a back-pack-mounted combustion engine power source and mechanical power transmission bet
38、ween the power source and the cutting attachment. Methods for the elimination or reduction of hazards arising from the use of these machines and the type of information on safe working practices to be provided by the manufacturer are specified.This part of ISO 11806, taken together with the relevant
39、 clauses of ISO 11806-1 (see 4.1), deals with all significant hazards, hazardous situations and hazardous events, with the exception of whole-body vibration from the back-pack power unit, relevant to these machines when they are used as intended and under conditions of misuse which are reasonably fo
40、reseeable by the manufacturer.NOTE 1 A standardized test procedure for measuring whole-body vibration from the back-pack power unit is presently not available.NOTE 2 See Annex A, together with Annex A in ISO 11806-1:2011, for a list of significant hazards.This part of ISO 11806 is applicable to port
41、able, hand-held, powered brush-cutters and grass-trimmers manufactured after its date of publication.This part of ISO 11806 is not applicable to machines equipped with metallic cutting attachments consisting of more than one piece, e.g. pivoting chains or flail blades.2 Normative referencesThe follo
