33、2011 has been approved by CEN as a EN ISO 22868:2011 without any modification. “ 3 DIN EN ISO 22868:2011-06 EN ISO 22868:2011 (E) Introduction This document is a type-C standard as stated in ISO 12100.1)The machinery concerned and the extent to which hazards, hazardous situations or hazardous events

34、 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 requirements of the other standards for machines that have been de

35、signed and built according to the requirements of this type-C standard. During the first steps in the preparation of this International Standard it became obvious that the repeatability of the test results could become better if the operator were to be replaced by a simulation process, representing

36、the normal operating modes with chain-saws and trimmers/brush-cutters. Furthermore, it was found that the cutting process performed with chain-saws causes considerable deviations, which are not related to the measured object but to the test procedure itself. Based on these observations, it was concl

37、uded that the operators in both test procedures, i.e. for chain-saws and trimmers/brush-cutters, ought to be replaced by a defined fixture and the cutting process with chain-saws by a brake simulating the load. In this manner, the operating conditions during measurement would simulate normal operati

38、ng conditions. The determination of noise emission characteristics is primarily intended for manufacturers declarations of noise emitted, comparing the noise emitted by machines in the family concerned, and purposes of noise control at source at the design stage. The use of this noise test code will

39、 ensure reproducibility of the determination of the noise emission characteristics within specified limits determined by the grade of accuracy of the basic noise measurement method used. Noise measurement methods allowed by this International Standard give results with Grade 2 accuracy. The operatin

40、g modes specified for the tests are consistent with those involved in the assessment of the exposure sound pressure levels, for example, over a typical working day. NOTE Exposure sound pressure levels are the mean sound pressure levels experienced by the operator over a defined period of time. The w

41、ork cycles chosen for this test code are based on the following considerations of application: a) chain-saws with an engine of 80 cm3are used for various operations, including felling, bucking and delimbing; b) chain-saws with an engine of W 80 cm3are normally used for felling and bucking. Delimbing

42、 will cause the saw to run at racing speed; therefore, racing is included only for saws with a 80 cm3engine. 1) Safety of machinery General principles for design Risk assessment and risk reduction. 4 DIN EN ISO 22868:2011-06 EN ISO 22868:2011 (E) For brush-cutters, grass-trimmers, hedge-trimmers and

43、 pole-mounted powered pruners, the cutting mode (full load) is estimated to be valid only for short periods, while racing and idling are the two dominant modes. Moreover, it has also been found to be diverse and not able to be performed under repeatable conditions. For trimmers, the full load and th

44、e racing modes are integrated in one single mode due to the loading effect of the flexible line. For brush-cutters, hedge-trimmers and pole-mounted powered pruners, it is not possible to simulate the full load mode in a feasible way since there are no constant load conditions comparable to chain-saw

45、s. Since the operating mode “racing” is anyhow the worst case, it is used as representative. For garden blowers, full load and idling are the two dominant modes. In either case, transport and other tasks between operations will cause the machine to run at idling. Experience has lead to the conclusio

46、n that, except for hedge-trimmers and blowers, equal duration for the different working modes is a good estimation of daily exposure. For hedge-trimmers, experience has shown that the machine is used 1/5 at idling and 4/5 at racing, while for garden blowers it is used 1/7 at idling and 6/7 at racing

47、. A summary of results from “round robin” tests, carried out between 2007 and 2008 in up to eight test laboratories on a single chain-saw, brush-saw and grass-trimmer, is given in Annex G. 5 DIN EN ISO 22868:2011-06 EN ISO 22868:2011 (E) CAUTION Some of the test procedures specified in this Internat

48、ional Standard involve processes that could lead to a hazardous situation. Any person performing tests in accordance with this International Standard shall be appropriately trained in the type of work to be carried out. 1 Scope This International Standard specifies a noise test code for determining, efficiently and under standardized conditions, the noise emission characteristics of portable, hand-held, combustion-engine-powered forest and garden machines, including chain-saws, brush-cutters
