27、,-BS EN ISO 22867:2011ForewordISO (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
28、subject for which a technical committee 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
29、 (IEC) on all matters of electrotechnical 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 commi
30、ttees are circulated to the member 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
31、 held responsible for identifying any or all such patent rights.ISO 22867 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 17, Manually portable forest machinery.This second edition cancels and replaces the first edition (ISO 22867:2
32、004), which has been technically revised. The scope has been expanded to include hand-held garden equipment. It also incorporates Technical Corrigendum ISO 22867:2004/Cor 1:2006.ISO 22867:2011(E)iv ISO 2011 All rights reservedCopyright European Committee for Standardization Provided by IHS under lic
33、ense with CENNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-BS EN ISO 22867:2011IntroductionThis 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
34、indicated in the Scope of this document.When requirements of this type-C standard are different from those which are stated in type-A or -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
35、according to the requirements of this type-C standard.The vibration test code specified in this International Standard is based on ISO 20643, which gives general specifications for the measurement of the vibration emission of hand-held machinery. It differs from ISO 20643 in the number of operators
36、required to be involved in the test, with ISO 20643 requiring at least three operators and this International Standard only one. Another difference is that this International Standard primarily positions the transducers next to the hand in the area between the thumb and the index finger, where they
37、present the least disturbance to the operator gripping the machine.The determination of vibration characteristics is primarily used for manufacturers declarations, comparing data between machines in the machine family concerned, development work at the design stage, and the estimation of the vibrati
38、on risk considering the specific conditions (parameters).The use of this vibration test code will ensure reproducibility of the determination of the vibration characteristics. Measurements made during particular operating modes are of interest for assessment of the vibration exposure, for example, o
39、ver a typical working day.The work cycles chosen for this test code are based on the following considerations of application:a) chain-saws with an engine displacement of 0,50 null (0,1 10) % of nullA.2.3 Operating conditionsThe machine shall be operated upright and with the guide bar nose protruding
40、 outside the test timber, in accordance with Figure A.3.The log shall be horizontally and rigidly mounted on a stiff support so that its centreline is (800 100) mm above ground level.ISO 22867:2011(E)8 ISO 2011 All rights reservedCopyright European Committee for Standardization Provided by IHS under

The engine speed shall be kept at maximum engine power, determined
45、in accordance with ISO 7293, by controlling the applied feed force on the handles.The vibration measurements shall be taken in the middle third through the log with the complete bar tip free outside the log. The rotational frequency of the engine shall be controlled by the cutting force. There shall
46、 be no contact between the test timber and the engine/motor part of the machine or the spiked bumper, if provided. Only the bar and the saw chain shall come into contact with the test timber.A.3.4 RacingPerform the measurements at an engine speed of 133 % of the speed at maximum engine power, determ
47、ined in accordance with ISO 7293.If the engine has a speed limiter set below that speed, measure at the maximum speed achievable. If the engine does not run at a stable speed, carry out the test at the maximum possible stable speed; this speed shall not, however, be more than 8 r/s below the maximum
48、 speed as determined by the speed limiter. The engine speed shall be controlled with the throttle trigger. A.4 Calculation of equivalent vibration total valuesA.4.1 GeneralThe equivalent vibration total values are determined by means of work cycles. These are composed of components of equal time duration where the components for chain-saws with an engine displacement of 80 cm3are the idling, full load and racing modes and, for chain-saws with an engine displacement 80 cm3, the idling and full load modes.A.4.2 Chain-saws with engine displacement 80 cm3The equivalent vibrati
