Grade S O-rings are designed for applications which require higher quality standards in regards to permissible deviations and surface qualities. Inside diameters, cross-sections, tolerances and isl identification code ISOFluid power systems and components — Vocabulary ISOAerospace fluid systems — O-rings, inch series: If these details are to be used for any other purpose than implementation then the prior written permission of BSI must be obtained.
Attention is drawn to isl possibility that some of the elements of this document may be the subject of patent rights. For dated references, only the edition cited applies. This part of ISO is also applicable to O-rings to be used in aerospace construction. Flow Marks radial orientation of flow marks is not permissible.
ISO shall not be held responsible for identifying any or all such 301-3 rights.
International organizations, governmental and non-governmental, in liaison with ISO, also take 361-3 in the work. For undated references, the latest edition of the referenced document including any amendments applies.
Combined Flash combination 360-13 offset, flash and parting line projection. Other methods should be agreed between the manufacturer and the user. It supersedes BS The main task of technical committees is to prepare International Standards. All dimensions in mm. 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.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. BSI offers members an 3601-33 updating service called PLUS which ensures that subscribers automatically receive the latest editions of standards.
Various BSI electronic information services are also available which give details on all its products and services. Components must be designed to meet these requirements under varying conditions. 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. Figure 4 — Flow marks a Acceptable within dimensional limits.
There are more than three in any 25mm length of circumference They interconnect There ido 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. Quality acceptance criteria Transmissions hydrauliques et pneumatiques — Joints toriques — Partie 3: Subscribing members of BSI are kept up to date with standards developments and receive substantial discounts on the purchase price of standards.

It presents the UK view on standards in Europe and at the international level. 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. It is the constant aim of BSI to improve the quality of our products and services. The BSI copyright notice displayed in this document indicates when the document was last issued.

Anti-extrusion devices back-up rings Li ce ns ed c op y: ISO consists of the following parts, under the general title Fluid power systems — O-rings: Inside diameters and cross sections, tolerances and size-identification codes — Part 2: Standard tolerances for non-hydraulic systems 3 Terms, definitions and symbols For the purposes of this document, the terms and definitions given in ISO and the following apply.
BSI also holds the copyright, in isp UK, of the publications of the international standardization bodies. Each member kso interested in a subject for which a technical committee has been established has the right to be represented on that committee. Grade S O-rings are available upon request.
For example, aerospace or critical industrial or automotive applications are covered by this grade. It is incorporated by Royal Charter. 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.
