Overview
ISO 3601-3:2005/Amd 1:2018 is an amendment to the international standard that specifies quality acceptance criteria for O-rings used in fluid power systems, including hydraulic and pneumatic transmissions. As part of the ISO 3601 series, this amendment refines the dimensional limits and classification of surface defects for molded O-rings without radial joints. It serves as a critical guideline for manufacturers and users, especially in industries requiring high reliability such as aerospace engineering.
This amendment updates and replaces previous criteria focusing on defect tolerances and quality levels, providing enhanced clarity and precision for inspection procedures. The standard facilitates the consistent production and assessment of O-rings, ensuring optimum sealing performance in fluid power applications.
Key Topics
Scope and Application
Defines quality acceptance criteria for O-rings sized according to ISO 3601-1 and related parts. The criteria apply globally to O-rings utilized in fluid power systems and aerospace constructions.Defect Classification and Limits
Establishes detailed classifications of O-ring defects by type (e.g., burrs, offsets, lack of material) and maximum permissible dimensional limits based on the O-ring's section diameter. Defect criteria are split into classes such as Class N and Class S, each with tailored defect limits.Dimension Tables for Defects
Contains updated tables (Table 1 and Table 2) describing allowable defect sizes for different O-ring diameters. The amendment introduces tolerance ranges for diameters greater than 8.4 mm and revises criteria for combined defects like burrs and offsets.Surface Defect Descriptions
Provides schematic representations and definitions for common surface imperfections including:- Burr height and combined burr/offset measurements
- Cropping or material removal limits
- Excessive flashing flatness
- Filling marks and material shortages
Amendment Highlights
- Removal of burr criteria for combined burr defects in certain classes
- Additional tolerance ranges for larger diameter O-rings
- Clarification on maximum defect sizes relative to internal diameters
Applications
ISO 3601-3:2005/Amd 1:2018 is essential for industries where O-rings are crucial for sealing and fluid containment, including but not limited to:
Hydraulic Systems
Ensures sealing components meet rigorous quality standards for high-pressure power transmission.Pneumatic Systems
Verifies O-rings’ dimensional accuracy and surface integrity for reliable air or gas sealing.Aerospace Engineering
Applies stringent criteria to O-rings used in aircraft and spacecraft to guarantee safety and performance under extreme conditions.Manufacturing Quality Control
Provides a reference framework for inspection processes, helping manufacturers minimize defects and improve product consistency.Component Testing and Certification
Enables regulatory compliance and product certification aligned with international agreements.
Related Standards
ISO 3601-1: Specifies the dimensions and tolerances for O-rings used in fluid power systems, forming the foundational sizing guide referenced by the quality criteria in Part 3.
ISO 16031-1 and ISO 16031-2: Complementary standards addressing additional dimensional and sealing requirements for O-rings.
ISO/IEC Directives, Parts 1 & 2: Outline the procedures and drafting rules followed in the creation and amendment of ISO standards.
ISO 3601 Series: The comprehensive set of international standards covering O-ring design, dimensions, material specifications, and testing.
By applying ISO 3601-3:2005/Amd 1:2018, organizations benefit from internationally recognized quality benchmarks for O-ring acceptance, enhancing product reliability and facilitating smoother trade and compliance in fluid power and aerospace industries worldwide.

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. 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 International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
