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).

Introduction
This document specifies the fastener inspection documents which can be supplied when requested at
the time of the order.
Before publication of this document, inspection documents according to ISO 10474 or EN 10204 were
also applied for fasteners. This document was developed specifically for fasteners, as a preferred
alternative to ISO 10474 or EN 10204.
Data in inspection documents may be collected from in-process control during the manufacture of the
fasteners and/or from final control on the finished fasteners based on sampling. In-process control
during manufacture within a certified quality assurance system operated by the manufacturer gives
the most reliable information about conformance of the fasteners (for more information regarding
acceptance inspection or quality assurance for fasteners, see ISO 3269 or ISO 16426).
Inspection documents for fasteners may include material, mechanical, physical, dimensional, functional
and finish-coating properties, as agreed at the time of the order.
