International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Internation
38、al Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. 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

International Standard 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.

42、n This part of ISO 11681 has been prepared for a special type of chain-saws used by trained persons for tree service work up in trees. This part of ISO 11681 differs from ISO 11681-11) as follows: Clause 1: !the tree service chain-saws are limited in size by the maximum allowed dry mass of 4,3 kg; C
43、lause 3: a definition of trained operator has been added and that for chain saws for tree service has been changed;“ subclause 4.1: the required handle dimensions have been altered; subclause 4.3: !a requirement for the sideways balance, measured in accordance with a new Annex D, has been added with
44、 a limited holding moment of 6 Nm; subclause 4.4: the non-manual chain-brake system shall meet stricter requirements than those in ISO 13772 and the allowed kickback angle has been reduced to 25;“ subclause 4.6: a permanently fixed spiked bumper is excluded; !Text deleted“ subclause 4.12: the requir
45、ement has been modified to be valid for an engine-stopping device (instead of an ignition switch); subclause 4.13: the requirement for protection from contact with parts under high voltage has been enlarged to include a requirement for an ignition interruption or short-circuiting device on the low v
46、oltage side and a method to verify, by inspection and use of a finger probe, the protection of the operator from unintentional contact with parts under high voltage; subclause 4.16: the requirement for protection from hot parts has been enlarged to all parts of the machine and a reference to EN 563
47、has been added; !Text deleted“ subclause 4.21: a requirement for an attachment point has been added; subclause 6.2: additional information is required; subclause 6.3: !new safety warnings have been added along with a new Annex E; subclause 6.4: new markings on the saw and information at the point of
48、 sale are requested, examples of the symbols to be used are given in a new Annex F“. Machinery is to comply as appropriate with ISO/TR 12100 for hazards which are not covered by this part of ISO 11681. 1 Scope This part of ISO 11681 specifies safety requirements and their verification for the design
49、 and construction of portable combustion-engined, hand-held chain-saws for tree service, designed for use by !a trained operator for pruning and dismantling standing tree crowns. It is applicable to chain-saws having a maximum mass of the saw equal to 4,3 kg, without guide bar and saw chain and with empty tanks“. It describes methods for the elimination or reduction of hazards a
