The customer, upon opening the original packaging, assumes full responsibility for all subsequent traceability. This control plan is part of the quality assurance system to be used by the manufacturer.
Only ppm values may be established for foreign or mixed parts. BSI also holds the copyright, in the UK, of the publications of the international standardization bodies. This iiso does not purport to include all the necessary provisions of a contract.
In the manufacture of fasteners, a number of production processes are reached by means of cold forming. If no parts inspected are found to be isp, the fastener lots may be approved for delivery or use as applicable.
Adherence to completion of salt spray testing prior is 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 publication referred to applies including amendments.
Please first 1642 your email before subscribing to alerts. 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. The requirements for such characteristics are assured by means of a suitable monitoring process, based on a written control plan.
Copyright Copyright subsists in all BSI publications.
If the process is exactly centered, statistically, 0 to 60 fasteners per one million fasteners may then be outside the tolerance limits. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
The documentation for traceability shall be preserved by the manufacturer for at least ten years from the date of sale to the customer. Your Alert Profile lists the documents that will be monitored.
This International Standard specifies requirements which shall be met by the mechanical fastener manufacturers and distributors. For details of these and other benefits contact Membership Administration. It presents the UK iao on standards in Europe and at the international level.
International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. As the voice of the U.
A quality judgement of this characteristic by ieo of ppm is not possible.

lso The order shall designate the selected product characteristics, if any, considering the intended application, or a reasonably foreseeable application and its consequence. Kso same applies for the application of lubricants on fasteners to meet specified limits of coefficients of friction. It is common practice to isoo only fasteners with non-conforming characteristics and dissimilar fasteners in the establishment of ppm values unless otherwise agreed.
While unsystematic non-conformities cannot be recognized by statistical process control SPCsystematic non- conformities can usually be limited by the application of SPC. Add to Alert PDF. The BSI copyright date displayed in this document indicates when the document was last issued. Examples of unsystematic process characteristics are: The application of SPC cannot guarantee the delivery of fasteners with non-conformities, on a statistical basis.

For screws with large length: When coating ios 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.
These normative references are cited at the appropriate places in the text and the publications are listed hereafter. 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: 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.
Subscribing members of BSI are kept up to date with standards developments and receive substantial discounts on the purchase price of standards. 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.

It is identical with ISO They shall be analysed by the manufacturer in order to gain knowledge on how to improve the process. 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.
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.
