6301-3 diameters, cross-sections, tolerances and size identification code ISOFluid power systems and components — Vocabulary ISOAerospace fluid systems — O-rings, inch series: This second edition cancels and replaces the first edition ISO Quality acceptance criteria Transmissions hydrauliques et pneumatiques — Joints toriques — Partie 3: For example, critical service aerospace or medical applications, where the surface of the O-ring must be near-perfect to perform in a satisfactory manner, are covered by this grade.
Testing of components to meet performance requirement provides users a basis of assurance for determining design application and for checking component compliance with their stated requirements.
Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. For dated references, only the edition cited applies.
This publication does not purport to include all the necessary provisions of a contract. Flow marks, non-fills and indentations within the limits of the above table shall not be allowed if: This part of ISO also defines and classifies surface imperfections on O-rings and specifies maximum acceptable limits for these imperfections.
Suitability of elastomeric materials for industrial applications The following parts are in preparation: International organizations, governmental 360-13 non-governmental, in liaison with ISO, also take part in the work. For example, aerospace or critical industrial or automotive applications are covered by this grade.
