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. 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 accordance 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 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, 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. IS0 6953 consists of the following parts, under the general title Pneumatic fluid power - Compressed air pressure regulators and filter-regulators: - Part I : Main characteristics to be included in literature from suppliers and product-marking requirements - Part 2: Test methods to determine the main characteristics to be included in literature from suppliers O IS0 2000 -All rights reserved iii Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/22/2007 09:33:04 MDTNo reproduction or networking permitted without license from IHS -,-,- STD-IS0 6953-L-ENGL 2OOO I 4851903 0844330 T 2 1 E IS0 6953-1 :2000(E) Introduction In pneumatic fluid power systems, power is transmitted and controlled through air under pressure circulating within a circuit. Where reduction and regulation of the pressure is desired, the regulators and filter-regulators are components designed to maintain the compressed air pressure approximately constant. iv O IS0 2000 - All rights reserved Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/22/2007 09:33:04 MDTNo reproduction or networking permitted without license from IHS -,-,- STD-ISO b953-L-ENGL 2000 = 4851903 0844733 968 W INTERNATIONAL STAN DARD IS0 6953-1 :2000(E) Pneumatic fluid power - Compressed air pressure regulators and filter-regulators - Part 1: Main characteristics to be included in literature from suppliers and product-marking requirements 1 Scope This part 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 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 removed 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 listed in IS0 2944. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions o f this part of IS0 6953. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties 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. For undated references, the latest edition of the normative document referred to applies. Members of IS0 and IEC maintain registers of currently valid International Standards.

The connecting interface for flange-mounted designs may be plain ported and counterbored to accept O-rings. For certain applications and connections other port forms may be employed. 4.2.3 Rated pressure Compressed air pressure regulators and filter-regulators shall be classified according to their rated pressure, selected from IS0 2944. The rated pressure shall be verified using the test procedure specified in ISO6953-2:2000, clause 6. This procedure verifies the pressure rating of the pressure-containing envelope but does not cover the limitation that may be imposed by the diaphragm. The range of duties and sensitivities of the diaphragms used varies widely and their strength may be limited to achieve the accuracy required by the application. 4.2.4 Range of operating temperatures 4.2.4.1 regulator are not impaired shal
