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.
