27、nd explanation concerning the principles of this International Standard 1 6 Bibliography . 18 Introduction Although every fastener should meet all the requirements of the standard to which it is specified, in mass production this is not always possible. The manufacturer is expected to take due care
28、during all stages of production so that the risk of parts that do not satisfy requirements is minimized. Nevertheless, the control processes used for that purpose are not the subject of this International Standard. The purchaser may wish to confirm whether, considering the limitations of inspection
29、by attributes of a fastener lot, it is reasonable to assume that the delivered fasteners were made to specification. In any case, it must be recognised that quality assessment of this sort cannot provide complete confidence that nonconforming fasteners do not exist within a production lot. It is des
30、irable that both supplier and purchaser possess a clear understanding of the quality-assessment processes to be used by the purchaser. Consequently, this International Standard defines those requirements to be applied by the purchaser where no other prior agreement exists, However, specification of
31、acceptable quality level (AQL) values does not imply the suppliers right to knowingly supply a nonconforming unit. NOTE A new IS0 International Standard is to be developed to take into account fasteners produced under in-process control and a certified quality assurance system operated by the manufa
32、cturer. The new standard will also cover special agreements for selected characteristics. Page 4 EN IS0 3269 : 2000 1 Scope 1.1 This International Standard specifies the acceptance inspection procedure that the purchaser of fasteners must follow in order to determine whether a lot of fasteners will
33、be accepted or rejected in cases where no other such procedure was agreed with the supplier at the time the fasteners were ordered. Additional requirements for acceptance may be included in a specific product standard (for example, one on prevailing torque-type nuts). The same procedure is also to b
34、e applied in cases where conformance to specification is disputed. 1.2 This International Standard is applicable to bolts, screws, studs, nuts, pins, washers, blind rivets and other related fasteners not intended for high volume machine assembly, special-purpose applications or specially engineered
35、applications requiring greater in-process control and lot traceability (see the note in the introduction). The procedure for these products shall be agreed upon by the supplier and the purchaser prior to the confirmation of the order. 1.3 any particular in-process control procedure or inspection dur
36、ing production. 1.4 The production of accessories, services and partially fabricated parts (for example, washers, nuts, plating, heat treatment and blanks) for use in the manufacture of fasteners may be subcontracted to other suppliers by the fastener supplier. Nevertheless, the supplier of the fina
37、l, finished product shall be solely responsible for the fasteners quality. This International Standard is applicable only to fully manufactured products; it neither implies nor includes The requirements of this International Standard apply only to the condition of fasteners at the time of delivery.
38、Any process carried out after receipt (for example, plating) will invalidate the requirements of this International Standard. 1.5 Standard is based.
