24、ational 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 established has the right to be represented on that committee. Inter
25、national 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 standardization.International Standards are drafted in accordance with the
26、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. Publication as an International Standard requires approval by a
27、t 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. ISO shall not be held responsible for identifying any or all such patent rights.ISO 11680-2 was prepared by Technical Committee ISO/T

34、e1 ScopeThis part of ISO 11680 gives safety requirements and measures for their verification for the design and construction of portable, hand-held, pole-mounted powered pruners with a back-pack power unit and using a drive shaft to transmit power to a cutting attachment consisting of a saw chain or
35、 reciprocating or circular saw blade (hereafter referred to as “machine”). 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 11680, togethe
36、r with the relevant sections of ISO 11680-1, deals with all significant hazards, hazardous situations or hazardous events with the exception of electric shock from contact with overhead electric lines (apart from warnings and advice for inclusion in the instruction handbook) and whole-body vibration
37、 from the back-pack power unit, relevant to these machines when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.NOTE 1 A standardized test procedure for measuring whole-body vibration from the backpack power unit is presently not availabl
38、e.NOTE 2 See Annex A for a list of significant hazards.This part of ISO 11680 is applicable to portable, hand-held, pole-mounted powered pruners with back-pack power unit manufactured after its date of publication.2 Normative referencesThe following referenced documents are indispensable for the app

In addition, the machine shall be designed according to the principles of ISO 12100 for relevant but not significant hazards which are not dealt with by this part of ISO 11680.Machines shall comply with ISO 11680-1:2011, Clause 4, except f
45、or 4.3.The safe operation of a machine also depends on the safe environment associated with the use of personal protective equipment (PPE), such as gloves, boots and eye and hearing protective equipment, as well as safe working procedures (see ISO 11680-1:2011, 5.1).Except where otherwise specified
46、in this part of ISO 11680, the safety distances specified in ISO 13857:2008, 4.2.4.1 and 4.2.4.3, shall be met.4.2 Handgrip on backpack power unit4.2.1 RequirementsA hand-grip shall be available which may be a part of the frame and which shall allow an operator to grasp the back-pack power unit for
47、handling and transport.The hand-grip shall be designed such that it can be fully gripped by an operator when wearing gloves, it provides the necessary sureness of grip by its shaping and surface, its length is at least 100 mm and where, for a bail or closed hand-grip, this length is straight or curv
