24、onal 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 committee has been established has the right to be represented on that committee. Internat

25、ional 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 electrotechnical standardization.International Standards are drafted in accordance with the rul

26、es 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 member bodies for voting. Publication as an International Standard requires approval by at l

30、vered are 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

31、and built 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

32、operators 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, w

33、here they 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 t

34、he vibration 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

35、example, over 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

36、protruding 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 reservedBS EN ISO 22867:2011Dimensions in millimetres80010021Key1 ce

38、ull load.During operation, the chain saw shall be held with the guide bar centreline horizontal and the guide bar plane vertical.A.3.2 IdlingThe idling speed shall be adjusted according to the machine manufacturers instructions. Perform the measurements with the throttle trigger fully released. The

39、saw chain shall not move during the test.ISO 22867:2011(E) ISO 2011 All rights reserved 9BS EN ISO 22867:2011A.3.3 Full loadPerform the measurements during crosscutting and with the throttle fully open. The engine speed shall be kept at maximum engine power, determined in accordance with ISO 7293, b

40、y 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 be no contact between the tes

41、t 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, determined in accordance with ISO 72

42、93.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 speed as determined by the sp

43、eed 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

44、 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 vibration total value, ahv,eq, shall be determined froma a

For machines with bicycle-type handles, the accelerometers shall be

47、located 50 mm 3 mm outside the centre of the gripping areas, in accordance with Figure B.1. For machines with a rear handle and loop-type front handle, the accelerometer on the rear handle shall be located 20 mm 3 mm in front of the rear of the throttle trigger. If this distance cannot be obtained,

48、the accelerometer shall be placed at the front of that portion of the handle intended to be grasped. The accelerometer for the front hand shall be located 50 mm 3 mm to the right of the centre of the gripping area. See Figure B.2. For machines with a rear handle and the front handle on the tube, the

49、 accelerometer on the rear handle shall be located 20 mm 3 mm in front of the rear of the throttle trigger. If this distance cannot be obtained, the accelerometer shall be placed at the front of that portion of the handle intended to be grasped, in accordance with Figure B.2. The accelerometer for the front hand shall be located 50 mm 3 mm in front of the centre of the gripping area or, if there is no designated gripping area, 250 mm 5 mm in front of the centre of the rear-handle accelerometer.B.2 Adj
