24、odies). 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. International organizations, governmental a
25、nd 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 rules given in the ISO/IEC Directives,
26、 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 at least 75 % of the member bodies cast
27、ing a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

33、1(E)Machinery for forestry Portable chain-saw safety requirements and testing Part 1:Chain-saws for forest service1 ScopeThis part of ISO 11681 gives safety requirements and measures for their verification for the design and construction of portable, combustion-engine, hand-held chain-saws, intended
34、 to be used for forest work by only one operator, by persons with the right hand on the rear handle and left hand on the front handle having read and understood the safety requirements provided in the instruction handbook and using the appropriate personal protective equipment (PPE). Methods for the
35、 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 11681 deals with all significant hazards, hazardous situations and hazardous events, with the exception
36、of kickback and balance for machines with an engine displacement of more than 80 cm3, relevant to these machines when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.NOTE See Annex A for a list of significant hazards.This part of ISO 1168
37、1 is applicable to chain-saws manufactured after its date of publication.2 Normative referencesThe following referenced documents are indispensable for the application of this document.

In addition, the machine shall be designed according to the principles of ISO 1210
47、0 for relevant but not significant hazards which are not dealt with by this part of ISO 11681.The safe operation of a chain-saw also depends on the safe environment associated with the use of personal protective equipment (PPE), such as gloves, slip-resistant footwear, and leg, eye, hearing and head
48、 protective equipment, as well as safe working procedures (see 5.1).Except where otherwise specified in this part of ISO 11681, the safety distances specified in ISO 13857:2008, 4.2.4.1 and 4.2.4.3, shall be met.4.2 Handles4.2.1 RequirementsChain-saws shall have a handle for each hand. These handles
49、 shall be designed such that they can be fully gripped by an operator wearing protective gloves, they provide the necessary sureness of grip by their shaping and surface, and they conform to the dimensions and clearances given in ISO 7914 (see also 4.12.1).The strength of both handles shall comply with ISO 7915.Chain-saws having a system for isolating machine vibration from the handles shall be designed so that the operator is able to stop the engine in a cont
