For example, aerospace or critical industrial or automotive applications are covered by this grade. Other methods should be agreed between the manufacturer and the user. 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. Each member body interested in a subject for which a technical committee has been established isl the right to be represented on that committee. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.

All dimensions in mm.

The main task of technical committees is to prepare International Standards. It is the constant aim of BSI to 36013- the quality of our products and services. Amendments issued since publication Amd. It supersedes BS Grade N O-rings are used in general applications and satisfy the high demands on dynamic and static sealing.

It is incorporated by Royal Charter. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

Grade S O-rings are available upon request. If these details are to be used for any other purpose than implementation then the prior written permission of BSI must be obtained. Quality acceptance criteria Transmissions hydrauliques et pneumatiques — Joints toriques — Partie 3: Flow Marks radial orientation of flow marks is not permissible. Suitability of elastomeric materials for industrial applications The following parts are in preparation: This publication does not purport to include all the necessary provisions of a contract.


BSI offers members an individual updating service called PLUS which ensures that subscribers automatically receive the latest editions of standards.

ISO consists of the following parts, under the general title Fluid power systems — O-rings: Grade S O-rings are designed for applications which require higher quality standards in regards to permissible deviations and surface qualities.

Standards and sizes

Permissible tolerances are classified into grade levels. 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.

Combined Flash combination of offset, flash and parting line projection. Figure 4 — Flow marks a Acceptable within dimensional limits.
