The revised global O-Ring standard - background & explanations
Feb 25, 2009
ISO 3601, the standard covering O-Rings, the most commonly used seal, has been revised to meet American, European, as well as Asian needs. ISO 3601 consolidates the long established AS 568B inch standard with the existing metric ISO 3601 and importantly, as it retains its original designation, means modification of documentation may not be required.
Revised - Inside diameters, cross-sections, tolerances and designation codes
- Dimensions are expressed in both metric and inch measurements
- Class A is identical with AS568B
- Class B is similar to the tolerances of the previous ISO 3601-1: 2002 and includes an equation to calculate the tolerance for the O-Ring inside diameter
- Range for O-Ring cross-section diameter tolerances from 0.8 mm to 8.4 mm
ISO 3601-2: 2008
New - Housing dimensions for general applications
- Covers technology for measuring surface roughness of O-Ring housings
- Design recommendations for O-Ring squeeze, elongation and compression as well as maximum groove fill
- Equation for calculation of O-Ring cross-section reduction caused by the elongation of the O-Ring inner diameter
ISO 3601-3: 2005
Partially revised - Quality acceptance criteria for O-Ring surfaces
ISO 3601-4: 2008
New – Retaining ring specifications
- Covers spiral Back-up Rings, solid type (cut/ uncut), concave type (cut/ uncut)
- Gives tolerances for outer and inner diameters depending on rod or piston applications
- Design recommendations but no size list for preferred housing dimensions
ISO 3601-5:2002
Currently in revision – Suitability of elastomeric materials for industrial applications
- Will replace general information on material groups with detailed information of more practical use to design engineers
- Will comprise detailed material specifications for important material groups Trelleborg Sealing Solutions has a high level of expertise in specification of O-Rings and other sealing elements within a wide range of industrial, aerospace and automotive applications. Design engineers can contact one of over 40 marketing companies worldwide for further information on this O-Ring standard or selecting the optimum sealing element for their specific application.
