27、national 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 subject for which a technical committee has
28、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 (IEC) on all matters of electrotechnical st
29、andardization. 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 committees are circulated to the member bodies
30、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 held responsible for identifying any or
31、all such patent rights. ISO 22868 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 17, Manually portable forest machinery. This first edition of ISO 22868 cancels and replaces ISO 7182:1984, ISO 7917:1987, ISO 9207:1995 and ISO 10884
32、:1995, of which it constitutes a technical revision. EN ISO 22868:2005 Licensed Copy: sheffieldun sheffieldun, na, Sat Nov 18 02:13:16 GMT+00:00 2006, Uncontrolled Copy, (c) BSI v Introduction During the first steps in the revision of this International Standard, it became obvious that the repeatabi
33、lity of the test results could become better if the operator were to be replaced by a simulation process, representing 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, w
34、hich are not related to the measured object but to the test procedure itself. Based on these observations, it was concluded 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
35、 a brake simulating the load. In this manner, the operating conditions during measurement would simulate normal operating conditions. The determination of noise emission characteristics is primarily used for manufacturers declarations of noise emitted, comparing the noise emitted by machines in the
36、family concerned, and purposes of noise control at source at the design stage. The use of this noise test code will 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
37、. Noise measurement methods allowed by this International Standard give results with Grade 2 accuracy. The operating modes are of interest for assessment of the exposure sound pressure levels, for example, over a typical working day. The work cycles chosen for this test code are based on the followi
38、ng considerations of application: a) chain-saws with an engine of 80 cm3 are used for various operations, including felling, bucking and delimbing; b) chain-saws with an engine of W 80 cm3 are normally used for felling and bucking. Delimbing will cause the saw to run at racing speed; therefore, raci
39、ng is included only for saws with a 80 cm3 engine. For brush-cutters and grass-trimmers, 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 been found to be diverse and not able to be performed under repe
40、atable conditions. For trimmers, the full load and the racing modes are integrated in one single mode due to the loading effect of the flexible line. For brush-cutters, it is not possible to simulate the full load mode in a feasible way since there are no constant load conditions comparable to chain
41、-saws. Since the operating mode “racing” is anyhow the worst case, it is used as representative. In either case, transport and other tasks between operations will cause the machine to run at idling. Experience has lead to the conclusion that equal duration for the different working modes is a good e
42、stimation of daily exposure.

43、SANDADR IS:86822 O5002(E) 1 Forestry machinery Noise test code for portable hand-held machines with internal combustion engine Engineering method (Grade 2 accuracy) 1 Scope This International Standard specifies a noise test code for determining, efficiently and under standardized conditions, the noi
44、se emission characteristics of portable, hand-held, internal combustion-engine-powered forest machines such as chain-saws, brush-cutters and grass-trimmers. Noise emission characteristics include the A-weighted emission sound pressure level at the operator position and the A-weighted sound power lev
45、el. The code is applicable for manufacturers product controls as well as type tests. It is intended that the results obtained will be able to be used to compare different machines or different models of the same type of machine. Although the noise emission values determined are obtained in an artifi
46、cial operation, they are representative of noise emission in a real work situation. 2 Normative references The following referenced documents are indispensable for the application of this document.
