Inside diameters, cross-sections, tolerances and size identification code ISOFluid power systems and components — Vocabulary ISOAerospace fluid systems — O-rings, inch series: Deviations of the curved cross section are permissible when the flattened area transitions into the curve of the circular cross section smoothly, and the cross section still falls within the permissible tolerances.
Revisions British Standards are updated by amendment or revision.
Users of British Standards should make sure that they possess kso latest amendments or editions. There are more than three in any 25mm length of circumference They interconnect There are more than three that are separated from each other by a distance that is less than the maximum limiting dimensions of such imperfection Reproduced with permission of the German Standards Institute DIN.

Flow marks, non-fills and indentations within the limits of the above table shall not be allowed if: Information regarding online access to British Standards via British Standards Online can be found at http: The main task of 301-3 committees is to prepare International Standards.
A list of organizations represented on this committee can be obtained on request to its secretary. Grade S O-rings are available upon request.
ISO shall not be held responsible for identifying any or all such patent rights. Standards are also available from the BSI website at is In response to orders for international standards, it is BSI policy to supply the BSI implementation of those that have been published as British Standards, unless otherwise requested. The work of preparing International Standards is normally carried out through ISO technical committees. For example, aerospace or iiso industrial or automotive applications are covered by this grade.
Buying standards Orders for all BSI, international and foreign standards publications should be addressed to Customer Services. This part of ISO is also applicable to O-rings to be 36013- in aerospace construction.
Quality acceptance criteria Transmissions hydrauliques et pneumatiques — Joints toriques — Partie 3: 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. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
This part of ISO also defines and classifies surface imperfections on O-rings and specifies maximum acceptable limits for these isk. The following table defines shape and surface deviations in o-rings per grade levels N and S 1 According to which value is the larger.
