    ISO 3601

     

    Welcome To Pacific Certifications!

    ISO 3601-1:2012(EN) Fluid power systems — O-rings — 

    Part 1: Inside diameters, cross-sections, tolerances, and designation codes
    ISO 3601 was created by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 7, and Sealing devices. ISO 3601-1:2012 is the fifth edition, it was canceled and replaced the fourth edition (ISO 3601-1:2008), which has been technically revised. It also incorporates the Technical Corrigenda ISO 3601-1:2008/Cor 1:2009 and ISO 3601-1:2008/Cor 2:2009.
    ISO 3601 consists of the following parts, under the general title Fluid power systems — O-rings:
    ISO 3601-1:2012(EN) Fluid power systems — O-rings — Part 1: Inside diameters, cross-sections, tolerances, and designation codes— Part 2: Housing dimensions for general applications
    ISO 3601-1:2012 specifies the inside diameters, cross-sections, tolerances, and designation codes for O-rings used in fluid power systems for general industrial and aerospace applications.
    The dimensions and tolerances specified in ISO 3601-1:2012 are suitable for any elastomeric material, provided that suitable tooling is available.

    ISO 3601-2:2016(EN) Fluid power systems — O-rings — Part 2: Housing dimensions for general applications
    ISO 3601-2:2016 defines the housing (gland) dimensions for class A O-rings for general industrial applications conforming to ISO 3601-1, as well as housing dimensions for class B O-rings used on selected metric-dimensioned hardware, e.g. fluid power cylinder bores and piston rods. These O-rings are to be used in general hydraulic and pneumatic applications without and with anti-extrusion rings (back-up rings). The dimensions of the O-rings (d1 and d2), size codes (SC), and tolerances conform to ISO 3601-1.

    ISO 3601-3:2005(EN)Fluid power systems — O-rings — Part 3: Quality acceptance criteria— Part 4: Anti-extrusion rings (back-up rings)
    ISO 3601-3:2005 defines the quality acceptance criteria of O-rings used in fluid systems, the dimensions of which are standardized in ISO 3601-1, ISO 16031-1, and ISO 16031-2.
    ISO 3601-3:2005 also defines and classifies surface imperfections on O-rings and specifies maximum acceptable limits for these imperfections. ISO 3601-3:2005 is also applicable to O-rings to be used in aerospace construction.
    ISO 3601-4:2008(EN)Fluid power systems — O-rings — Part 4: Anti-extrusion rings (back-up rings)
    ISO 3601-4:2008 defines dimensions and tolerances for five types of anti-extrusion rings, which are also known as backup rings:
    a) Spiral type (T1);
    b) Angle cut type (T2);
    c) Solid type (T3);
    d) Angle cut concave type (T4);
    e) Solid concave type (T5).
    These anti-extrusion rings are for use with selected O-ring sizes as specified in ISO 3601-1 and the relevant housing dimensions specified in ISO 3601-2016
    ISO 3601-5:2015(EN) Fluid power systems — O-rings — Part 5: Specification of elastomeric materials for industrial applications
    ISO 3601-5:2015 contains the material specification of a selection of standard elastomeric materials (rubber) for O-rings used in general industrial applications. It also indicates the ability of the materials to satisfy many of the requirements associated with fluid power components.
    Only materials which are in use universally are specified; other compounds are available and can be used. The required physical properties and test methods (including test specimen) should be agreed upon between the equipment manufacturer/user and the O-ring manufacturer/supplier.
