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.

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.

Fasteners — Types of inspection documents
1 Scope
This document specifies the different types of fastener inspection documents issued by the fastener
manufacturer or distributor and/or by the external authorized representative on specific request of the
purchaser at the time of the order.
— declaration of compliance (F2.1);
— test reports (F2.2, F3.1 and F3.2).
NOTE The term “certificate” is in common use, however for fastener inspection documents the terminology
to be used is “test report”.
This document specifies requirements for the content of each fastener inspection document, in
conjunction with the order, the relevant standards and/or specified requirements.
This document is applicable to finished fasteners such as bolts, screws, studs, nuts, washers, pins,
rivets, etc. made of steel, stainless steel, non-ferrous metal or non-metallic material.
This document does not apply to special-purpose or specially engineered applications requiring other
types of procedures (e.g. initial samples).
Examples of inspection documents are given in Annex A. An example of a coding system identifying the
sections in fastener inspection documents is given in Annex B.

and/or specified requirements. The fasteners inspected and/or tested are not necessarily part of the
actually delivered fasteners provided that they
— are in accordance with the same standard or technical specification,
— are manufactured from the same material designation,
— are manufactured with the same manufacturing sequences and under same conditions,
— have the same shape, and
— have similar dimensions, where the differences do not impact the test results.
4.2.2 Specific inspection for fasteners
Inspection carried out before delivery, on the fasteners from the original manufacturing lot and in
accordance with the product specification, in order to verify that the fasteners comply with the order
and relevant standards and/or specified requirements.

the distributor's authorized representative.
4.3.5 Fastener test report F3.2
Document issued by the manufacturer or distributor declaring that the delivered fasteners are in

Inspection document in accordance with this document is only supplied on request of the purchaser.
The type of inspection document, F2.1, F2.2, F3.1 or F3.2 shall be agreed at the time of the order.
Fasteners produced in accordance with a product standard (and/or technical specification) shall meet
all the applicable requirements, regardless of which controls are performed during manufacturing
and/or final inspection. It is the responsibility of the manufacturer and distributor to apply suitable

SIST EN ISO 16228:2018
ISO 16228:2017(E)

methods of their choice, such as in-process control or final inspection, to ensure that the manufactured
lot does conform to the specified requirements.
Even when receiving an inspection document, the purchaser is responsible for the approval of
the delivered fasteners by acceptance inspection procedures in accordance with ISO 3269 unless
otherwise agreed.
The inspection documents F2.1 and F2.2 should include the fastener manufacturing lot number of the
delivered fasteners, however a trace lot number may replace or complement the manufacturing lot
number. The inspection documents F3.1 and F3.2 shall include the fastener manufacturing lot number
of the delivered fasteners.
Each inspection document is only valid for the as-delivered condition of the related fasteners referenced
in the inspection document. Any further processing after delivery (e.g. coating) altering the fasteners
may invalidate all or part of the content of the inspection document.
5.2 Maintenance of data for inspection documents
The fastener supplier issuing an inspection document shall maintain in-process control and/or final
test/inspection records either in hardcopy or electronically for a minimum period of three years.
5.3 Traceability
Fasteners shall be fully traceable by the manufacturing lot number (or trace lot number), and to
maintain lot integrity, manufacturing lots shall not be commingled.
NOTE For the definitions of manufacturing lot number, trace lot number and commingling, see ISO 1891-4.
The purchaser who receives the fastener inspection document is responsible for maintaining
subsequent traceability when required. Upon opening the original packaging, the purchaser assumes
full responsibility for all subsequent traceability.
In case of dispute, the supplier shall be able to provide all necessary documentation and test/inspection
records related to the manufacturing lot number (or trace lot number).
5.4 Inspection document sources
The fastener manufacturer is allowed to
— generate F2.1, F2.2, F3.1 or F3.2 inspection documents, and
— transfer the original data from suppliers into the manufacturer inspection document, provided that
full traceability is ensured; the test/inspection results of the original inspection document shall not
be modified.
The pass-through distributor and repackaging distributor are allowed to
— generate F2.1 or F2.2 inspection documents only by transferring data from F2.1 or F2.2 from the
manufacturer,
— generate F3.1 or F3.2 inspection documents,
— supply the incoming inspection document F2.1, F2.2, F3.1 or F.3.2 from the manufacturer, and
— transfer the original data from F3.1 of the manufacturer into the distributor F3.1 inspection
document, provided that full traceability is ensured; the test/inspection results of the original
inspection document shall not be modified.
The alteration distributor is allowed to
— generate F2.1 inspection documents only by transferring data from the manufacturer,
