Fasteners - Quality assurance system (ISO 16426:2002)

ISO 16426 specifies requirements for a fastener quality assurance system to be met by the fastener manufacturers and distributors. These requirements are intended to reduce or prevent the production of non-conforming fasteners with the objective of approaching zero defects for the characteristics specified.
This International Standard outlines the requirements from receipt of raw material through the manufacturing process to delivery at the distributor or the user, who is the installer.

Verbindungselemente - Qualitätssicherungssystem (ISO 16426:2002)

Diese Internationale Norm legt Anforderungen an ein Qualitätssicherungssystem fest, die von den Herstellern und Vertreibern von Verbindungselementen erfüllt werden müssen. Diese Anforderungen sind dazu vorgesehen, die Fertigung von fehlerhaften Verbindungselementen zu verringern oder zu verhindern, mit dem Ziel, sich dem Zustand "Null-Mängel" für festgelegte Eigenschaften anzunähern.
Diese Internationale Norm legt die Anforderungen von der Übernahme des Ausgangswerkstoffes über den Herstellungsprozess bis zur Lieferung an den Vertreiber oder den Verbraucher, der die Verbindungselemente montiert, fest.

Eléments de fixation - Systeme d'assurance qualité (ISO 16426:2002)

L'ISO 16426:2002 spécifie les exigences auxquelles doivent répondre le fabricant d'éléments de fixation mécaniques et les distributeurs. Ces exigences en système d'assurance qualité visent à réduire ou à empêcher la production d'éléments de fixation non conformes, et ont pour objectif de s'approcher du zéro défaut en ce qui a trait aux caractéristiques spécifiées.
L'ISO 16426:2002 fixe les exigences à partir de la réception de la matière première en passant par le processus de fabrication jusqu'à la livraison au distributeur ou à l'utilisateur, qui est l'installateur.

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.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.

Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.

Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

International Standard ISO 16426 was prepared by Technical Committee ISO/TC 2, Fasteners.

Introduction

This International Standard is the second in a series of two standards for mechanical fastener quality using a

detection system and a prevention system respectively.

— ISO 3269 deals with acceptance inspection based on statistical sampling of fasteners at a given AQL level at the

time of receiving and constitutes a detection system intended primarily for use by the customer.

— ISO 16426 deals with fully traceable mechanical fasteners which have been produced under a verifiable quality

assurance system and constitutes a prevention system intended primarily for use by the fastener manufacturer.
