EN ISO 22867:2011 (E) DIN EN ISO 22867:2012-04 3 IntroductionThis document is a type-C standard as stated in ISO 12100.The machinery concerned and the extent

30、 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 are stated in type-A or -B standards, the requirements of this type-C standard take precedence over the require

31、ments of the other standards for machines that have been designed 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 o

32、f hand-held machinery. It differs from ISO 20643 in the number of 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

33、 to the hand in the area between the thumb and the index finger, where 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 concer

34、ned, development work at the design stage, and the estimation of the 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 mo

35、des are of interest for assessment of the vibration exposure, for 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 conditions

36、The machine shall be operated upright and with the guide bar nose 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.EN ISO 22867:2011 (E) DIN EN ISO 22867:20

38、ith an engine displacement of 80 cm3idling and full 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 measurement

The saw chain shall not move during the test.EN ISO 22867:2011 (E) DIN EN ISO 22867:2012-04 13 A.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

40、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

41、 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

42、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

43、 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 dur

44、ation 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 vibration total value, ahv,e

For machines with bicycle-type handles, the accelerometer

47、s shall be 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

48、 obtained, 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
