7、-,- ISO 3601-1:2002(E) ISO 2002 All rights reserved 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
8、. 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. ISO collaborates closely with the Intern
9、ational Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Sta
10、ndards 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 ISO 3601 may be
11、the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 3601-1 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 7, Sealing devices. This third edition cancels and replaces the second edition (ISO 3601-1:19
12、88), which has been technically revised. ISO 3601 consists of the following parts, under the general title Fluid power systems O-rings: Part 1: Inside diameters, cross-sections, tolerances and size identification code Part 2: Housing dimensions for general applications Part 3: Quality acceptance cri
13、teria Part 4: Anti-extrusion devices (back-up rings) Part 5: Suitability of elastomeric materials for industrial applications -,-,- ISO 3601-1:2002(E) iv ISO 2002 All rights reserved Introduction In fluid power systems, power is transmitted and controlled through a fluid (liquid or gas) under pressu
14、re within an enclosed circuit. Components need to be designed to meet these requirements under varying conditions. Testing of components to meet performance requirements provides users with a basis of assurance for determining design application and for checking component compliance with their state
15、d requirements. -,-,- INTERNATIONAL STANDARD ISO 3601-1:2002(E) ISO 2002 All rights reserved 1 Fluid power systems O-rings Part 1: Inside diameters, cross-sections, tolerances and size identification code 1 Scope This part of ISO 3601 specifies the inside diameters, cross-sections, tolerances and si
16、ze identification code for O-rings used in fluid power systems for general purpose applications (series G), as well as for aerospace and similar applications (series A). The dimensions and tolerances specified in this part of ISO 3601 are suitable for any elastomeric material, provided that suitable
17、 tooling is available. NOTE The tooling most commonly available is based on 70 IRHD NBR shrinkage rates (see ISO 48). For materials that shrink differently from this standard NBR compound, a special mould can be required to maintain the mean diameters and the tolerance limits listed. 2 Normative ref
18、erences The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 3601. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this pa
19、rt of ISO 3601 are encouraged to investigate the possibility of applying the most recent additions of the normative documents indicated below. For undated references, the last edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid Internat

NOTE Throughout this part of I
21、SO 3601, the term “O-ring” has been adopted, although the correct term is “toroidal sealing ring”. 1) To be published.

Figure 1 Typical O-ring configuration 6 Inside diameters, d1, cross-sections (section diameter), d2, and tolerances The combination of inside diameters, cross-sections and tolerances sha
23、ll be chosen from Table 2 for general purpose applications (series G) or from Table 3 for aerospace and similar applications, where smaller tolerance limits are recommended (series A). See note in clause 1. NOTE Most of the dimensions for the inside diameter were selected from the series of preferre
24、d numbers (see ISO 3). The tolerances for the inside diameters d1 of series G (Table 2) were calculated using the following formula: Tolerance d1 = ( d10,95 0,009) + 0,11 The tolerances for the inside diameters d1 of series A (Table 3) were calculated using the following formula: Tolerance d1 = ( d1
25、0,96 0,007) + 0,09 The calculated results shall be rounded to two places after the comma from 5 to 9 in the third place to the next higher 1/100 mm and from 1 to 4 in the third place to the next lower 1/100 mm.
