It is the constant aim of BSI to improve the quality of our products and services. To achieve this aim, intermediate objectives are set by specifying criteria for evaluating the delivered quality of fasteners. Please first verify your email before subscribing to alerts.

This publication does not purport to include all the necessary provisions of a contract. The manufacturer shall be able to provide documentation for uso manufacturing lot, to prove the compliance of the fasteners to the specifications, and this shall include at least: If the document is revised or amended, you will be notified by email.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. This does not preclude the free use, in the isso of implementing the standard, of necessary details such 14626 symbols, and size, type or grade designations. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. 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 work of preparing International Standards is normally carried out through ISO technical committees. Isl corresponding tolerances are specified considering the individual part and production method.


BS EN ISO 16426:2002

In the production of threaded fasteners, there are differences in the screw threads based on the method in which the threads are formed which affect geometry, tolerances, roughness, thread laps, etc. The machines used today in the production of fasteners e. For undated references the latest edition of the publication referred to applies including amendments. 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.

As the voice of the U. 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. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. BSI also holds the copyright, in the UK, of the publications of the international standardization bodies.

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. In such cases, depending on the type and geometry of the fastener, corrosion resistance is based on significant surfaces of the fastener. While unsystematic non-conformities cannot be recognized by statistical process control SPCsystematic non- conformities can usually be limited by the application of SPC.

In case of dispute, the supplier shall be able to provide all necessary information relating to the manufacturing lot number. Amendments issued since publication Amd. 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.

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

The customer, upon opening the original packaging, assumes full responsibility for all subsequent traceability. In the manufacture of fasteners, a number of production processes are reached by oso of cold forming.

The shipping document shall include at least the designation of the fasteners and the manufacturing lot number or trace number.

With an automatic inspection process, usually four or five characteristics are checked simultaneously. Information regarding online access to British Standards via British Standards Online can be found at http: This International Standard specifies requirements which shall be met by the mechanical fastener manufacturers and distributors. Already Subscribed to this document. 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 The quality objective, zero defects, cannot be realized with today’s state-of-the-art methods.


They shall be analysed by the manufacturer in order to gain knowledge on how to improve the process. This control plan is part of the quality assurance system to be used by the manufacturer.

This is schematically illustrated in Figure A. 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.

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 hours. For undated references, the latest edition of the normative document referred to applies. The order shall designate the selected product characteristics, if any, considering the intended application, or a reasonably foreseeable application and its consequence. It presents the UK view on standards in Europe and at the international level.

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.
