Steel and steel products - Location and preparation of samples and test pieces for mechanical testing (ISO 377:2017)
This document specifies requirements for the identification, location and preparation of samples and test
pieces intended for mechanical tests on steel sections, bars, rod, flat products and tubular products as
defined in ISO 6929. If agreed in the order, this document can also apply to other metallic products. These
samples and test pieces are for use in tests that are carried out in conformity with the methods specified
in the product or material standard or, in the absence of this, in the standard for the test method.
Where the requirements of the order or product standard differ from those given in this document,
then the requirements of the order or product standard apply.
Stahl und Stahlerzeugnisse - Lage und Vorbereitung von Probenabschnitten und Proben für mechanische Prüfungen (ISO 377:2017)
Diese Internationale Norm legt Anforderungen an die Kennzeichnung, Lage und Vorbereitung von Probenabschnitten und Proben für mechanische Prüfungen an den in ISO 6929 definierten Profilen, Stäben, Walzdraht, Flacherzeugnissen und rohrförmigen Erzeugnissen aus Stahl fest. Falls bei der Bestellung vereinbart, kann diese Internationale Norm auch für andere metallische Erzeugnisse gelten.
Die Probenabschnitte und Proben sind für Prüfungen bestimmt, die nach den in der Erzeugnis- oder Werkstoffnorm festgelegten Verfahren oder, falls in diesen nichts angegeben ist, nach dem in der Prüfnorm angegebenen Verfahren durchgeführt werden.
Wenn die Anforderungen in der Bestellung oder der Erzeugnisnorm von den Anforderungen nach dieser Internationalen Norm abweichen, so gelten die Anforderungen entsprechend der Bestellung oder der Erzeugnisnorm.
Acier et produits en acier - Position et préparation des échantillons et éprouvettes pour essais mécaniques (ISO 377:2017)
L'ISO 377:2017 définit les exigences relatives à l'identification, à la position et à la préparation des échantillons et éprouvettes destinés aux essais mécaniques des profilés, barres, fils machine, et produits plats et tubulaires en acier, tels que définis dans I'ISO 6929. Par accord à la commande, l'ISO 377:2017 peut également s'appliquer à d'autres produits métalliques. Elle n'est pas applicable aux essais non destructifs. Ces échantillons et éprouvettes sont à utiliser dans les essais effectués conformément aux méthodes prescrites dans la norme de produit ou, en absence de celle-ci, dans la norme d'essai.
Lorsque les exigences de la commande ou de la norme de produit différent de celles données dans l'ISO 377:2017, les exigences définies à la commande ou prescrites dans la norme de produit s'appliquent.

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.

Steel and steel products — Location and preparation of
samples and test pieces for mechanical testing
1 Scope
This document specifies requirements for the identification, location and preparation of samples and test
pieces intended for mechanical tests on steel sections, bars, rod, flat products and tubular products as
defined in ISO 6929. If agreed in the order, this document can also apply to other metallic products. These
samples and test pieces are for use in tests that are carried out in conformity with the methods specified
in the product or material standard or, in the absence of this, in the standard for the test method.
Where the requirements of the order or product standard differ from those given in this document,
then the requirements of the order or product standard apply.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

3.6
reference condition
condition of a sample, rough specimen or test piece having undergone a heat treatment to represent the
intended final condition of the product
Note 1 to entry: In such cases, the sample, rough specimen or test piece is called the reference sample, reference
rough specimen or reference test piece.
4 General requirements
4.1 Representative testing
Sample, rough specimens and test pieces selected in accordance with Annex A shall be considered to be
representative of the product.
NOTE As a result of their production sequence, e.g. melting, casting hot or cold forming or both, heat
treatment, etc., steel products are not homogeneous. The mechanical properties of samples taken from other
locations can be different.
4.2 Identification of sample products, samples, rough specimens and test pieces
Sample products, samples, rough specimens and test pieces shall be marked to ensure traceability to
the original product and their location and orientation in that product. For this purpose, if, during the
preparation of any one or more of the samples, rough specimens or test pieces, removal of the marks
cannot be avoided, transfer of these marks shall be carried out before the existing marks are removed
or, in the case of automatic preparation, equipment before the test piece is removed from the equipment.
In the case of specific inspection and where requested by the purchaser, the transfer of the marks shall
be carried out in the presence of the purchaser’s representative.
In the case of fully automatic in line preparation and testing systems, marking of samples, rough
specimens and test pieces is not necessary if an adequate control system exists, which defines the
procedures to follow in the event of system failure.
