The work of preparing International Standards is normally carried out through IS0 technical committees. Eac
9、h 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, govern- mental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the Internati
10、onal Electrotechnical Commission (IEC) 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 lnter- national Standard requires approval by at least 75 % of the member bod
11、ies casting a vote. International Standard IS0 2860 was prepared by Technical Committee ISO/TC 127, Earth-moving machinery, Sub-Committee SC 2, Safety re- quirements and human factors. This fourth edition cancels and replaces the third edition (IS0 2860:1983), of which it constitutes a technical rev

14、b) head access, c) body access, d) arm access, e) two-handed access. It provides engineers and designers with information in order that the access openings provided on equipment and machinery for purposes of in- spection, adjustment and maintenance have suffi- cient dimensions for the intended funct
15、ion by personnel in the field or shop. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard.

IS0 6165:1987, Earth-moving machinery - Basic types - Vocabulary. 3 Minimum access openings The dimensions shown in 3.1 to 3.4 are the rec- ommended minimum for limited activity through the opening. Larger op
18、enings will be needed in specific instances, depending upon the nature of the task, size and mass of the parts, etc. Such larger openings can be more useful and allow greater ef- ficiency. The larger openings for access with arctic clothing are for earth-moving machines and equipment in- tended for
19、use in cold environments. Based on available anthropometric data, the rec- ommended openings, in figures 1 to 5, are the smallest that will accommodate the 95th percentile operator as defined in IS0 3411. In all cases in 3.1 to 3.4, all corners may have an optional maximum 25 mm radius. IS0 2860:199
