2、stellen und Stellteilen (IS0 11 471 : 1995) This standard incorporates International Standard IS0 11471 Agricultural tractors and machinery - Coding of remote hydraulic power services and controls. National foreword This standard has been prepared by ISO/TC 23. The responsible German body involved i

3、n its preparation was the Normenausschu Maschinenbau (Mechanical Engineering Standards Committee), Section Landmaschinen und Traktoren. DIN EN IS0 3767-1 and DIN EN IS0 3767-2 are the standards corresponding to International Standards IS0 3767-1 and IS0 3767-2, respectively, referred to in clause 2

7、machinery Coding of remote hydraulic power services and controls Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical c

8、ommittees. Each member body interested in a subject for which a technical committee has 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. IS0 collaborates closely with t

9、he International Electrotechnical Commission (i EC) on all matters of electrotechnical standardization, 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 least 75 % of the

10、 member bodies casting a vote. International Standard IS0 11471 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcom- mittee SC 4, Tractors. 1 Scope This International Standard specifies the coding to be used to identify the couplings and control

11、s for the re- mote hydraulic power services of agricultural tractors, machinery and implements. The identification of couplings and controls will be useful to implement manufacturers to enable them to identify the implement hoses with the appropriate extended or retracted cylinder symbol. This will

12、help ensure proper operation of the implement when con- nected to the tractor. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publi- cation, the editions indicated were vali

13、d. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most re- cent editions of the standards indicated below. Members of IEC and IS0 maintain registers of cur- rently valid International
