5、2 DIN EN ISO 11680-2:2012-04 2 A comma is used as the decimal marker. Start of application The start of application of this standard is 1 April 2012. National foreword This standard includes safety requirements. This standard has been prepared by Technical Committee ISO/TC 23 “Tractors and machinery
6、 for agriculture and forestry”, Subcommittee SC 17 “Manually portable forest machinery” (Secretariat: SIS, Sweden) in collaboration with Technical Committee CEN/TC 144 “Tractors and machinery for agriculture and forestry”, Working Group WG 6 “Manually portable forestry machinery”, (Secretariat: AFNO
7、R, France). The responsible German body involved in its preparation was the Normenausschuss Eisen-, Blech- und Metallwaren (Hardware, Tinware and Metal Products Standards Committee), Working Committee NA 020-00-12 AA Tragbare Forstmaschinen. This standard contains specifications meeting the essentia
8、l requirements set out in Annex I of the “Machinery Directive”, Directive 2006/42/EC, which apply to pole-mounted powered pruners for use with a back-pack power source that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance wi
9、th the essential requirements of the directives. Once this standard 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 con
10、formity”). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. DIN and/or DKE shall not be held responsible for identifying any or all such patent rights. The ISO Standards referred to in clause 2 of this standard have been published
11、as the corresponding DIN EN ISO Standards with the same number. Amendments This standard differs from DIN EN ISO 11680-2:2009-01 and DIN EN ISO 11680-2 Corrigendum 1:2010-11 as follows: a) references to the corresponding clauses in DIN EN ISO 11680-1 regarding safety requirements and/or protective m
12、easures and information for use have been included; b) requirements for hand-grips, harnesses and hydraulic and pneumatic pipes and hoses have been rendered more precise; c) the list of significant hazards specifies in detail the origin (source) and the potential consequences.

30、 ISO 11680-2:2011 (E) 4 1 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 consi
31、sting of a saw chain or 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 par
32、t of ISO 11680, together 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) a
33、nd 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 foreseeable by the manufacturer.NOTE 1 A standardized test procedure for measuring whole-body vibration from the backpack power unit is
34、 presently not available.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 in

41、 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 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
42、.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 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 necess
