BRITISH STANDARD BS EN ISO Incorporating Corrigendum No. 1 Fasteners — Quality assurance system The European. Find the most up-to-date version of ISO at Engineering We are looking ISO , it was referenced in a document. The statement that can be found on it is: ISO specifies requirements for a fastener q.
The shipping document shall include at least the designation of the fasteners and the manufacturing lot number or trace number.
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. For undated references the latest edition of the publication referred to applies including amendments. A list of organizations represented on this committee 61426 be obtained on request to its secretary. For this reason, corrosion resistance is assured by means of suitable production management measures utilizing in-process control.
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.
The manufacturer shall be able to provide documentation for any manufacturing lot, to prove the compliance of is fasteners to the specifications, and this shall include at least: It is the constant aim of BSI to improve the quality of our products and services. It presents the UK view on standards in Europe and at the international level.
For screws with large length: It is common practice to include only fasteners with non-conforming characteristics and dissimilar fasteners in the establishment of ppm values unless otherwise agreed. Standards Subsctiption may be the perfect solution. Foreign or mixed parts can result either from the manufacturer’s production chain or the production chain of another party or from other sources. Users iwo responsible for its correct application.
The requirements for such characteristics are assured by means of a suitable monitoring process, based on a written control plan. 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.
This European Standard shall be given the status of a national standard, either jso publication of an identical text or by endorsement, at the latest by Mayand conflicting national standards shall be withdrawn at the latest by May A quality judgement of this characteristic by evaluation of ppm is not possible.
The adherence to such a specification e.
ISO – Fasteners — Quality assurance system
Any repackaging carried out by the distributor transfers the responsibilities from the manufacturer to the distributor for those characteristics which may be affected by the repackaging operation.

Buying standards Orders for all BSI, international and foreign standards publications should be addressed to Customer Services. These requirements, which constitute a quality assurance system, are intended to reduce or prevent the production of nonconforming fasteners with the objective of approaching zero defects for the charac-teristics.
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. The manufacturer 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 to the manufacturer.
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. You may delete a document from your Alert Profile at any time. With an automatic inspection process, usually four or five characteristics are checked simultaneously.
Standards are also available from the BSI website at http: Please first log in with a verified email before subscribing to alerts. For all other characteristics, the manufacturer may use the quality plan of his choice and the customer shall rely on ISO to evaluate the level of conformance of the purchased fasteners.
Examples of unsystematic process characteristics are: In such cases, it is often not possible to give clearly-defined tolerances or limit values.
So for these fasteners, on average, can be expected. Information regarding online access to British Standards via British Standards Online can be found at http: BSI also holds the copyright, in the UK, of the 164426 of the international standardization sio. Sharp edges cannot always be avoided with certain cold forming processes. In such 16246, depending on the type and geometry of the fastener, corrosion resistance is based on significant surfaces of the fastener.
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 and the coating method, and may cause differences in the local salt spray corrosion resistance. We have no amendments or corrections for this standard. It is identical with ISO This publication does not purport to include all the necessary provisions of a contract.
These normative references are cited jso the appropriate places in the text and the publications are listed hereafter. Users of British Standards should make sure that they possess the latest amendments or editions.
If the user considers that the degree to which the characteristic s deviate s from specified requirements will have no significant effect on 14626 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.
Only ppm values may be established for foreign or mixed parts.
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. Compliance with a British Standard does not of itself confer immunity from legal obligations.
The number of parts produced by a manufacturer can amount to up to several million per day, which requires special measures for maintaining the process capability. Special measures are taken to prevent mechanical damage especially at points of impact and to avoid contamination. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
