16、 federation of national 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
17、committee. International organizations, governmental 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. International Standards are drafted in acc
18、ordance with the rules given in the ISOAEC Directives, Part 3 . 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 member bodies casting a vote. Attention
19、 is drawn to the possibility that some of the elements of this part of IS0 6953 may be the subject of patent rights. IS0 shall not be held responsible for identifying any or all such patent rights. International Standard IS0 6953-1 was prepared by Technical Committee ISO/TC 131, Fluid power systems,
20、 Subcommittee SC 5, Control products and components. This second edition cancels and replaces the first edition (IS0 6953-1 :1990), which has been technically revised.

23、on In pneumatic fluid power systems, power is transmitted and controlled through air under pressure circulating within a circuit.

26、rt of IS0 6953 specifies the characteristics of compressed air pressure regulators to be included in literature from their suppliers. It also applies to filter-regulators. In addition, it specifies the product marking requirements for pressure regulators and filter-regulators. This pari of IS0 6953
27、is applicable to compressed air pressure regulators with a rated inlet pressure of up to 2 500 kPa 25 bar) and an outlet adjustment pressure of up to 1 600 kPa (16 bar), and to filter-regulators with rated inlet and outlet pressures of up to 1 600 kPa (16 bar), in which the major contaminants are re
28、moved by mechanical means. The maximum temperature is 80 O C for regulators and filter-regulators and applies to materials of construction that are light alloys (aluminium, etc.), zinc die-casting alloys, brass, steel and plastic. The rated pressure should be selected from the preferred pressures li

For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, part
30、ies to agreements based on this pari of IS0 6953 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.
