3、al standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 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. Internatio
4、nal organizations, govern- mental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical commit
5、tees are circulated to the member bodies for voting. Publication as an Inter- national Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 8909-3 was prepared by Technical Com- mittee lSO/TC 23, Tractors and machinery for agriculture and forest

9、ONAL STANDARD Q IS0 IS0 8909-3:1994(E) Forage harvesters - Part 3:. Test methods 1 Scope This part of IS0 8909 specifies test methods for evaluations of forage harvester function and per- formance, covering forage harvesters which cut the crop directly at full width or from spaced-apart plant rows,
10、or which pick up precut crop. It applies to forage harvesters with driven knives for chopping and which deliver the chopped crop into a container or a separate vehicle or trailer. The har- vesters may be tractor-mounted, trailed or self-pro- pelled. 2 Normative references The following standards con
11、tain provisions which, through reference in this text, constitute provisions of this part of IS0 8909. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of IS0 8909 are encouraged to investigate the poss
