7、2012 + Corr.1:2012) has been prepared by Technical Committee ISO/TC 131 “Fluid power systems”, Subcommittee SC 7 “Sealing devices”, Working Group WG 3 “Fluid power systems and components Sealing devices Design criteria for standard O-ring applications”. The responsible German body involved in its pr
8、eparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-36-73 AA O-Ringe of Section Fluidtechnik. Technical Corrigendum 1 to ISO 3601-1:2012 has been incorporated: in Table A.2, fifth row, “17,5 mm” has been replaced with “17,54 mm” and i
9、n Annex B, “37,2 lx” has been replaced with “400 lx”. Because the responsible German Committee had already influenced the development of ISO 3601-1:2008 to a great extent, the Committee decided to adopt it, unchanged, as DIN ISO 3601-1:2010-08. The revised edition of the International Standard (ISO
10、3601-1:2012) has thus been adopted, unchanged, as the present standard for the same reason. Even though the International Standard does not fully conform with national expectations due to different market philosophies among regional markets, the existence of an ISO Standard in parallel with a DIN St
11、andard can be done away with and the ISO Standard can be published as a DIN ISO Standard without any changes. International Standards referred to in this standard have been published as the corresponding DIN ISO or DIN EN ISO Standards with the same number. For ISO 5598, ISO 16031-1 and ISO 16031-2
12、there are no national standards available. Amendments This standard differs from DIN ISO 3601-1:2010-08 as follows: a) O-ring dimensions have been corrected; b) size codes have been corrected; c) the minimum illumination for the inspection of O-rings has been corrected; d) the standard has been edit
13、orially revised. Previous editions DIN 3771-1: 1984-12 DIN 3771-2: 1984-12 DIN ISO 3601-1: 2010-08 DIN ISO 3601-1:2013-11 Fluid power systems O-rings Part 1: Inside diameters, cross-sections, tolerances and designation codes Introduction In fluid power systems, power is transmitted and controlled th
14、rough a fluid (liquid or gas) under pressure within an enclosed circuit. To avoid leakage or to seal different chambers of a component from each other, sealing devices are used. O-rings are one type of sealing device. 4 1 Scope This part of ISO 3601 specifies the inside diameters, cross-sections, to
15、lerances and designation codes for O-rings used in fluid power systems for general industrial and aerospace applications. The dimensions and tolerances specified in this part of ISO 3601 are suitable for any elastomeric material, provided that suitable tooling is available. NOTE The tooling most com
16、monly 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 references The following referenced documents are i

Figure 1 Typical O-ring configuration 6 Inside diameters, d1, cross-sections (section diameter), d2, and
20、tolerances 6.1 The combinations of inside diameters and cross-section diameters shall be chosen depending on the application: from Tables 1 through 6 for general industrial applications; from Tables 7 through 11 for aerospace applications. 6.2 For industrial applications, two classes of inside diame
21、ter tolerances, class A and class B, are specified. The tolerance of class B O-rings is based on Equation (A.1). Class A O-rings have tighter inside diameter tolerances than class B O-rings and are suitable for industrial or aerospace applications when the application or the housing require tighter
22、tolerances. Class B O-rings have dimensions and tolerances suitable for general-purpose applications. The inside diameter tolerances are based on Equation (A.1). For information, Figure 2 shows a graphical comparison of the inside-diameter tolerances for class A and class B O-rings. 6.3 Cross-sectio
23、n tolerances for non-standard (custom) O-rings for general industrial applications not listed in Tables 1 through 6 can be chosen from Table A.1. Tolerances for inside diameters for non-standard (custom) class A O-rings are listed in Table A.2. Equation (A.1) can be used to calculate inside diameter
24、 tolerances for non-standard (custom) class B O-rings. In marginal cases, the compliance with the limits of the shape deviations and surface imperfections should be considered besides the dimensional tolerances. See ISO 3601-3.
