Fasteners - Acceptance inspection (ISO 3269:2019)
This document specifies an inspection procedure to be used by the purchaser where no prior agreement exists. It also specifies a reference acceptance procedure for acceptance or rejection of an inspection lot, when no agreement can be reached between the purchaser and the supplier, or where conformance to specification is disputed. It applies to inspection lots of bolts, screws, studs, nuts, pins, washers, rivets and other related fasteners. This document applies to fasteners not intended for high volume machine assembly, special-purpose applications or specially engineered applications requiring more advanced in-process control and lot traceability. For in-process control or final inspection by the manufacture and sorting, see ISO 16426.
Mechanische Verbindungselemente - Annahmeprüfung (ISO 3269:2019)
Dieses Dokument legt ein Prüfverfahren fest, das vom Käufer anzuwenden ist, wenn keine vorherige Ver-einbarung vorliegt.
Es legt außerdem auch ein Schieds Annahmeverfahren für die Annahme oder Rückweisung eines Prüfloses fest, wenn keine Vereinbarung zwischen dem Käufer und dem Lieferanten erzielt werden kann, oder wenn die Übereinstimmung mit der Spezifikation angezweifelt wird.
Es gilt für Prüflose von Schrauben, Bolzen, Muttern, Stiften, Scheiben, Nieten und weiteren ähnlichen Ver-bindungselementen.
Dieses Dokument gilt für Verbindungselemente, die nicht für den Zusammenbau von Hochleistungs-maschinen, Anwendungen für besondere Zwecke oder speziell entwickelte Anwendungen vorgesehen sind, die eine weitergehende Prozessüberwachung und Rückverfolgbarkeit der Lose erfordern.
Für die Prozessüberwachung oder Endprüfung bei der Herstellung und Sortierung, siehe ISO 16426.
Fixations - Contrôle réception (ISO 3269:2019)
Le présent document spécifie une procédure de contrôle à appliquer par le client si aucun accord préalable n'a été conclu.
Il spécifie également une procédure de réception de référence pour l'acceptation ou le rejet d'un lot de contrôle lorsqu'aucun accord n'a pu être conclu entre le client et le fournisseur, ou lorsque la conformité à la spécification fait l'objet d'un litige.
Il s'applique aux lots de réception de boulons, vis, goujons, écrous, goupilles, rondelles, rivets et autres fixations associées.
Le présent document s'applique aux fixations non destinées aux machines d'assemblage à gros débit, à des applications spéciales, ou à des applications particulières nécessitant un contrôle en cours de fabrication plus poussé et une traçabilité des lots.
Pour le contrôle en cours de fabrication, le contrôle final par le fabricant ou le contrôle par tri, voir l'ISO 16426.
Vezni elementi - Prevzemna kontrola (ISO 3269:2019)
Ta dokument določa postopek prevzemne kontrole, ki ga lahko uporabi kupec, če predhodnega dogovora ni. Prav tako določa referenčni postopek za prevzem ali zavrnitev kontrolne serije, kadar med kupcem in dobaviteljem ni mogoče doseči dogovora ali če je skladnost s specifikacijami sporna. Velja za kontrolne serije sornikov, vijakov, zatičev, matic, moznikov, podložk, zakovic in drugih povezanih veznih elementov. Dokument se uporablja za vezne elemente, ki niso namenjeni za montažo strojev masovne proizvodnje, posebne namene ali posebne vrste uporabe, pri katerih se zahteva naprednejša kontrola postopka in sledljivost serije. Za kontrolo med postopkom ali končno kontrolo v proizvodnji in sortiranje glej ISO 16426.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso

This document was prepared by Technical Committee ISO/TC 2, Fasteners, Subcommittee SC 7, Reference
standards.
This fourth edition cancels and replaces the third edition (ISO 3269:2000), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— introduction of an additional approach for incoming inspection with smaller sample sizes based
on N = 0;
A
— use of a reference approach in case agreement is not reached;
— sample size specified on the basis of lot size;
— addition of informative Annexes A and B explaining the basis for sample size selection.
Any feedback or questions on this document should be directed to the user’s national standards body. A

ISO 3269:2019(E)
Introduction
The manufacturer of fasteners is expected to take due care and apply process control (see ISO 16426)
during production in order to minimize the chances of producing parts that do not satisfy requirements
of the standard or technical specification to which they are specified. Although every fastener should
meet all the specified requirements, this objective is not guaranteed in mass production.
The purchaser of fasteners is expected to decide whether it is reasonable to assume that the delivered
fasteners were made to specification. Considering the limitations of inspection by attributes of a
fastener inspection lot, it is desirable that both the purchaser and the manufacturer (or supplier)
possess a clear understanding of the acceptance inspection procedure to be used by the purchaser. This
document describes an inspection procedure for use by the purchaser where no prior agreement exists.
Such acceptance inspection cannot provide complete confidence that non-conforming fasteners do
not exist within a production lot. Conversely, the acceptance of a lot based on acceptance quality limit
(AQL) values in this document does not imply that the supplier has a right to knowingly supply non-
conforming fasteners.
This fourth edition introduces a layered approach for incoming acceptance inspection that begins with
small sample sizes associated with a sampling plan based on Ac = 0.

Fasteners — Acceptance inspection
1 Scope
This document specifies an inspection procedure to be used by the purchaser where no prior
agreement exists.
It also specifies a reference acceptance procedure for acceptance or rejection of an inspection lot,
when no agreement can be reached between the purchaser and the supplier, or where conformance to
specification is disputed.
It applies to inspection lots of bolts, screws, studs, nuts, pins, washers, rivets and other related fasteners.
This document applies to fasteners not intended for high volume machine assembly, special-purpose
applications or specially engineered applications requiring more advanced in-process control and lot
traceability.
For in-process control or final inspection by the manufacture and sorting, see ISO 16426.
