Grade S O-rings are available upon request. For dated references, only the edition cited applies. This part of ISO also defines and classifies surface imperfections on O-rings and specifies maximum acceptable limits for these imperfections. All dimensions in mm. Various BSI electronic information services are also available which give details on all its products and services. For undated references, the latest edition of the referenced document including any amendments applies.
This publication does not purport to include all the necessary provisions of a contract. Grade N O-rings are used in general applications and satisfy the high demands on dynamic and static sealing. ISO shall not be held responsible for identifying any or all such patent rights. Copyright Copyright subsists in all BSI publications.

Combined Flash combination of offset, flash and parting line projection. If these details are to be used for any other purpose than implementation then the prior written permission of BSI must be obtained.
ISO consists of the following parts, under the general title Fluid power systems — O-rings: This does not preclude the free use, in the course of implementing the standard, of necessary details such as symbols, and size, type or grade designations. 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.
Information regarding online access to British Standards via British Standards Online can be found at http: 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.
Components must be designed to meet these requirements under varying conditions.
A list of organizations represented on this committee can be obtained on request to its secretary. Buying standards Orders for all BSI, international and foreign standards publications should be addressed to Customer Services.
Amendments issued since publication Amd. Permissible tolerances are classified into grade levels. Information on standards BSI provides a wide range of information on national, European and international standards through its Library and its Technical Help to Exporters Service.
International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. 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. The main task of technical committees is to prepare International Standards.
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.
Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee.

Subscribing members of BSI are kept up to date with standards developments and receive substantial discounts on the purchase price of standards. For example, critical service aerospace or medical applications, where the surface of the Isi must be 3061-3 to perform in a satisfactory manner, are covered by this grade.
Users of British Standards should make 3061-3 that they possess the latest amendments or editions. Suitability of elastomeric materials for industrial applications The following parts are in preparation: Quality acceptance criteria Transmissions hydrauliques et pneumatiques — Joints toriques — Partie 3: For details of these and other benefits contact Membership Administration.
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.
