Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Please first log in with a verified email before subscribing to alerts. The requirements for such characteristics are assured by means of a suitable monitoring process, based on a written control plan. If a characteristic is specified and is considered critical with respect to its intended use, all concerned parties are expected to take prudent measures to approach zero defects.

You may delete a document from your Alert Profile at any time.

If the user considers that 164226 degree to which the characteristic s deviate s from specified requirements will have no significant effect on the assembly or performance of the fasteners in their service application, the user may authorize a written release of the fasteners for completion of production or for shipment, as applicable.

Adherence to completion of salt spray testing prior to shipment is not always practical because of the testing time required which may exceed several hundred 14626.

If these details are to be used for any other purpose than implementation then the prior written permission of BSI must be obtained. For undated references the latest edition of the publication referred to applies including amendments.

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.

Information regarding online access to British Standards via British Standards Online can be found at http: Up-to-date lists and bibliographical references concerning 164426 national standards may be obtained on application to the Management Centre or to any CEN member.

The application of SPC cannot guarantee the delivery of fasteners with non-conformities, on a statistical basis. They shall be analysed by the manufacturer in order to gain knowledge on how to improve the process.


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 adherence to such a specification e. The work of preparing International Standards is normally carried out through ISO technical committees.

BS EN ISO 16426:2002

Standards Subsctiption may be the perfect solution. The customer, upon opening the original packaging, assumes full responsibility for all subsequent traceability. 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.

The number of parts produced by a manufacturer can amount to isi to several million per day, which requires special measures for maintaining the process capability. The documentation for traceability shall be preserved by the manufacturer for at least ten years from the date of sale to the customer. 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.

Experience has shown that for one single specified characteristic, after automatic 1626 there is still an average remaining level of non-conformities of about. Any repackaging carried out by the distributor transfers the responsibilities from 16246 manufacturer to the distributor for those characteristics which may be affected by the repackaging operation.

This is schematically illustrated in Figure A. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Contact the Information Centre. The shipping document shall include at least 164266 designation of the fasteners and the manufacturing lot number or trace number.

We have no document history for this standard. If the document 166426 revised or amended, you will be notified by email. Users of British Standards should make sure that they possess the latest amendments or editions. We would be grateful if anyone finding an inaccuracy or ambiguity while using this British Standard would inform the Secretary of the technical committee responsible, the identity of which can be found on the inside front cover.

It is identical with ISO This standard is also available to be isso in Standards Subscriptions. When coating the parts for corrosion protection, differences in the local thickness of the coating cannot be avoided and will vary depending on the part size 116426 the coating method, and may cause differences in the local salt spray corrosion resistance. Copyright Copyright subsists in all BSI publications.


Endorsement notice 164226 text of ISO The quality objective, zero defects, cannot be realized with today’s state-of-the-art methods.

Parts with non-conformities in measurements, geometry and other properties result 1626 unsystematic or systematic process characteristics. As the voice of the U. This International Standard outlines the requirements from receipt of raw material through the manufacturing process to delivery at the distributor or the user, who is the installer.

Annex A of this International Standard is for information only. 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. The BSI copyright date displayed in this document indicates when the document was last issued. This International Standard specifies requirements which shall be met by the mechanical fastener manufacturers and distributors.

Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. For screws with large length: These normative references are cited at the appropriate places in the text and the publications are listed hereafter.

These requirements, which constitute a quality assurance system, are intended to reduce or prevent the production of nonconforming fasteners oso the objective of approaching zero defects for the charac-teristics.

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. BSI offers members an individual updating service called 1642 which ensures that subscribers automatically receive the latest editions of standards. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

A quality judgement of this characteristic by evaluation of ppm is not possible.
