Compliance with a British Standard does not of itself confer immunity from legal obligations.

To achieve this aim, intermediate objectives are set by specifying criteria for evaluating the delivered quality of fasteners. It presents the UK view on standards in Europe and at the international level. These requirements are intended to reduce or isso the production of non- conforming fasteners with the objective of approaching zero defects for the characteristics specified.

The corresponding tolerances are specified considering the individual part and production method. 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.

It is identical with ISO For undated references the latest edition of the publication referred to applies including amendments. Please first verify your email before subscribing to alerts.

A quality judgement of this characteristic by evaluation of ppm is not possible. 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. If the document is revised or amended, you will be notified by email.

It is the constant aim of BSI to improve the quality of our products and services. The machines used today in the production of fasteners e. If these details are to be used for any other purpose than implementation then the prior written permission of BSI must be obtained. A list of organizations represented on this committee can be obtained on request to its secretary. The adherence to the tolerances depends not only on the material used but also on a number of other influencing factors; e.


Parts with non-conformities in measurements, geometry and other properties result from unsystematic or systematic process characteristics.

Sharp edges cannot always be avoided with certain cold forming processes. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.

Additionally, the user shall take all prudent measures to assure the integrity of the fasteners purchased in accordance with this International Standard. Foreign or mixed parts can result either from the manufacturer’s production chain or the production chain of another party or from other sources. This control plan is part of the quality assurance system to be used by the manufacturer.

In the manufacture of fasteners, a number of production processes are reached by means of cold forming. Standards Subsctiption may be the perfect solution. The manufacturer shall be able to provide documentation for any manufacturing lot, to prove the compliance of the fasteners to the specifications, and this shall include at least: Some examples are given below to illustrate this.

Users are responsible for its correct application. It is common practice to include only fasteners with non-conforming characteristics and dissimilar fasteners in the establishment of ppm values unless otherwise agreed. The application of SPC cannot guarantee the delivery of fasteners with non-conformities, on a statistical basis.

So for these fasteners, on average, can be expected. This publication does not purport to include all the necessary provisions of a contract. The same applies for the application of lubricants on fasteners to meet specified limits of coefficients of friction.

Various BSI electronic information services are also available which give details on all 16462 products and services. Users of British Standards should 61426 sure that they possess the latest amendments or editions. If, for instance, a value of 1,33 for a single characteristic is assumed, this means that of the fasteners are within the specification for this particular characteristic.

For isoo references, subsequent amendments to, or revisions of, any of these publications do not apply.

In such cases, depending on the type and geometry of the fastener, corrosion resistance is based on significant surfaces of the fastener. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by Mayand conflicting national standards shall be withdrawn at the latest by May These requirements, which constitute a quality assurance system, are intended to reduce or prevent the isi of nonconforming fasteners with the objective of approaching zero defects for the charac-teristics.
