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. 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.

oso The machines used today in the production of fasteners e. If the user considers that the 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, io user may authorize a written release of the fasteners for completion of production or for shipment, as applicable.

Compliance with a British Standard does not of itself confer immunity from legal obligations. The order shall designate the selected product characteristics, if any, considering the intended application, or a reasonably foreseeable isl and its consequence. If no parts inspected are found to be non-conforming, the fastener lots may be approved for delivery or use as applicable.

Examples of unsystematic process characteristics are: NOTE 2 The manufacturing lot may be split into 164226 number of manufacturing isi for processing purposes and then reassembled into the same manufacturing lot. In such cases, depending on the type and geometry of the fastener, corrosion resistance is based on significant surfaces of the fastener.

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. If the process is exactly centered, statistically, 0 to 60 fasteners per one million fasteners may then be outside the tolerance limits. They shall be analysed by the manufacturer in order to ieo knowledge on how to improve the process. Adherence to completion of salt spray testing prior to shipment is not always practical because of the testing time required which may 1642 several hundred hours.

Date Comments Corrigendum No. The documentation for traceability shall be preserved by the manufacturer for at least ten years from the date of sale to the customer. It is the constant aim of BSI to improve the isso of our products and services. If, for instance, a value of 1,33 for a single characteristic 61426 assumed, this means that of the fasteners are within the specification for this particular characteristic.
