24、O (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 committees. Each member body interested in a subject for which a technical co

25、mmittee 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 the International Electrotechnical Commission (IEC) on all matters of electro

26、technical 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 International Standards adopted by the technical committees are circulated to the memb

27、er 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 subject of patent rights. ISO shall not be held responsible for identifyin

28、g any or all such patent rights.ISO 11681-2 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 17, Manually portable forest machinery.This third edition cancels and replaces the second edition (ISO 11681-2:2006), which has been technic

29、ally revised.ISO 11681 consists of the following parts, under the general title Machinery for forestry Po rtable chain-saw safety requirements and testing: Part 1: Chain-saws for forest service Part 2: Chain-saws for tree serviceISO 11681-2:2011(E)iv ISO 2011 All rights reservedBS EN ISO 11681-2:201

30、1IntroductionThis document is a type-C standard as stated in ISO 12100.The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are covered are indicated in the scope of this document.When requirements of this type-C standard are different from those which ar

31、e stated in type-A or type-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 requirements of this type-C standard.At the time of publication of this edition, it was not st

32、ate of the art to require that starting of the machine would be always possible without causing movement of the saw chain. Such a requirement will be considered for inclusion in the next revision of this International Standard.ISO 11681-2:2011(E) ISO 2011 All rights reserved vBS EN ISO 11681-2:2011B

34、ree service of portable, combustion-engine, hand-held chain-saws having a maximum mass without guide bar or saw chain and with tanks empty of 4,3 kg, intended to be used, with the right hand on the rear handle and left hand on the front handle, by a trained operator for pruning and dismantling stand

35、ing tree crowns, and by persons having read and understood the safety requirements provided in the instruction handbook, using the appropriate personal protective equipment (PPE). Methods for the elimination or reduction of hazards arising from the use of these machines and the type of information o

36、n 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 relevant to these machines when they are used as intended and under conditions of misuse which are reasonably foreseeable by

37、the manufacturer.NOTE See Annex B for a list of significant hazards.This part of ISO 11681 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.
