12、SO 6953-1:2000(E) iii Foreword ISO (the International 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
13、 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. ISO collaborates closely with the International Electrotechnical Commissio
14、n (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an In
15、ternational 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 part of ISO 6953 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

This second edition cancels and replaces the first edition (ISO 6953-1:1990), which has been technically revised. ISO 6953 consists of the follow

Where r

21、gulators 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 part of ISO 6953 is applicable to compressed air pressure regulators with a rated inlet pre
22、ssure of up to 2 500 kPa 25 bar1) 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 removed by mechanical means. The maximum temperature is 80 C for regulators
23、 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 listed in ISO 2944. 2Normative references The following normative documents c
