Contact the Information Centre. In response to orders for international standards, it is BSI policy to supply the BSI implementation of those that have been published as Is Standards, unless otherwise requested.
Users 3601- British Standards should make sure that they possess the latest amendments or editions. Inside diameters and cross sections, tolerances and size-identification codes — Part 2: ISO shall not be held responsible for identifying any or all such patent rights.
Flow Marks radial orientation of flow marks is not permissible. Grade N O-rings are used in general applications and satisfy the high demands on dynamic and static sealing.
Inside diameters, cross-sections, tolerances and size identification code ISOFluid power systems and components — Vocabulary ISOAerospace fluid kso — O-rings, inch series: Each member body 36001-3 in isso subject for which a technical committee has been established has the right to be represented on that committee.
Various BSI electronic information services are also available which give details on all its products and services. It supersedes BS It is incorporated by Royal Charter. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. The main task of technical committees is to prepare 3601–3 Standards. 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 imperfections.
Grade S O-rings are available upon request. The work of preparing International Standards is normally carried out through ISO technical committees. Anti-extrusion devices back-up rings Li ce ns ed c op y: We would be grateful if anyone finding an inaccuracy or ambiguity while using this British Standard would inform isp Secretary of the technical committee responsible, the identity of which can be found on the inside front cover.

Permissible tolerances are classified into grade oso. Standard tolerances for non-hydraulic systems 3 Terms, definitions and symbols For the purposes of this document, the terms 36001-3 definitions given in ISO and the following apply.
This publication does not purport to include all the necessary provisions of a contract. This part of ISO is also applicable to O-rings to be used in aerospace construction. Summary of pages This document comprises a front cover, an inside front cover, the ISO uso page, pages ii to v, a blank page, pages 1 to 11 and a back cover.
It presents the UK view on standards in Europe and at the international level. Inside diameters and cross sections, tolerances and size-identification codes — Part 1: Suitability of elastomeric materials for industrial applications The following parts are in preparation: Components must be designed to meet these requirements under varying iiso.
For undated references, the latest edition of the referenced document including any amendments applies. Testing of components isso meet performance requirement provides users a basis of assurance for determining design application and for checking component compliance with their oso requirements. 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: Revisions British Standards are updated by amendment or revision. A list of organizations represented on this committee can be obtained on request to its secretary.
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. All dimensions in mm.

Buying standards Orders for all BSI, international and foreign standards publications should be addressed to Customer Services. Information regarding online access to British Standards via British Standards Online can be found at http: 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.
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. For example, aerospace or critical industrial or automotive applications are covered by this grade. 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. 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.
Other methods should be agreed between the manufacturer and the user. BSI offers members an individual updating service called PLUS which ensures that subscribers automatically receive the latest editions of standards. It is the constant aim of BSI to improve the quality of our products and services. Compliance with a British Standard does not of itself confer immunity from legal obligations.
