Only ppm values may be established for foreign or mixed parts. They shall be analysed by the manufacturer in order to gain knowledge on how to improve the process. These requirements are intended to reduce or prevent the production of non- conforming fasteners with the objective of approaching zero defects for the characteristics specified.

BSI offers members an individual updating service called PLUS which ensures that subscribers automatically receive the latest editions of standards. The requirements for such characteristics are assured by means of a suitable monitoring process, based on a written control plan. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Management Centre or to any CEN member.

Users of British Standards should make sure that they possess the latest amendments or editions. 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. It is the constant aim of BSI to improve the quality of our products and services. It is identical with ISO A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the Management Centre has the same status as the official versions.

The adherence to the tolerances depends not only on isi material used but also on a number of other influencing factors; e. Please first log in with a verified email before subscribing to alerts. The work of preparing International Standards is normally carried out through ISO technical committees.

Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Sharp edges cannot always be avoided with certain cold forming processes. In the manufacture of fasteners, a number of production processes are reached by means of cold forming. The corresponding tolerances are specified considering ido individual part and production method.

In addition, the parts are transferred into other vessels many times during the production process, the number of transfer operations depending on the length of the production chain e. So for these fasteners, on average, can be expected.

Add to Alert PDF. The order shall designate the selected product characteristics, if any, considering the intended application, or a reasonably foreseeable application and its consequence. NOTE 2 The manufacturing lot may be split into a number of manufacturing batches for processing purposes and then reassembled into the same manufacturing lot.


Experience has shown that for one single specified characteristic, after automatic inspection there is still an average remaining level of non-conformities of about. Date Comments Corrigendum No. Fasteners manufactured under the conditions of this International Standard shall be delivered in manufacturing lots. With an automatic inspection process, usually four or five characteristics are checked simultaneously.

Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.

To achieve this aim, intermediate objectives are set by specifying criteria for evaluating the delivered quality of fasteners. The quality objective, zero defects, cannot be realized with today’s state-of-the-art methods. If the isi is exactly centered, statistically, 0 to 60 fasteners per one million fasteners may then be outside the tolerance limits.

Buying standards Orders for all BSI, international and foreign standards publications should be addressed to Customer Services. Revisions British Standards are updated by amendment or revision.

The distributor shall be able to provide full manufacturing lot documentation for a ten year period from the date of the sale to the customer, provided the customer gives the manufacturing lot number or the trace number to the distributor.
