Overview
ISO 3601-1:2012/Cor 1:2012 is a technical corrigendum to the ISO 3601-1:2012 standard for fluid power systems - O-rings. Part 1 of ISO 3601 defines the inside diameters, cross-sections, tolerances and designation codes used for O-rings in hydraulic and pneumatic applications. This corrigendum, published 2012-07-15 by ISO Technical Committee ISO/TC 131, Subcommittee SC 7 (Sealing devices), issues precise corrections to numerical values in the original document to ensure dimensional accuracy and correct inspection conditions.
Key topics and technical requirements
- Dimensional definitions: Focus on standardizing O-ring inside diameters and cross-section sizes to enable interchangeability across manufacturers.
- Tolerances: Specifies dimensional tolerances that control allowable deviations for inside diameters and cross-sections; the corrigendum refines numeric values to maintain manufacturing and quality consistency.
- Designation codes: Standardized designation codes for identifying O-ring sizes and cross-sections in drawings, bills of materials and procurement.
- Corrections included in Cor 1:
- Table A.2 (page 32): replace “17,5” with “17,54” - a dimensional correction affecting a specific size entry.
- Clause B.1.2 (page 34): replace “37,2 lux” with “400 lux” - correcting the specified illumination level for inspection or measurement conditions.
Practical applications
- Ensures consistent O-ring selection and interchangeability in hydraulic and pneumatic systems.
- Supports manufacturing tolerancing and quality control procedures, where precise dimensions and inspection conditions are critical.
- Used in component specification, CAD modeling, procurement documentation and inventory coding to reduce mismatch and sealing failures.
- The correction to illumination (400 lux) clarifies inspection environment requirements for visual or optical measurement of sealing components.
Who uses this standard
- Design engineers specifying seals for fluid power systems.
- Manufacturers and tooling engineers producing O-rings.
- Quality assurance and metrology teams performing dimensional checks and acceptance testing.
- Purchasing and inventory specialists using designation codes to manage part lists.
- Test laboratories and certification bodies validating compliance with ISO 3601 series requirements.
Related standards
- Part of the ISO 3601 series addressing O-ring dimensions and sealing-device interfaces. Users should consult other parts of the ISO 3601 family for complementary requirements on housing dimensions, material considerations and assembly interfaces.
