Corrosion protection of steel structures by protective paint systems - Assessment of, and acceptance criteria for, the adhesion/cohesion (fracture strength) of a coating - Part 1: Pull-off testing (ISO/DIS 16276-1:2024)
ISO 16276-1:2007 specifies procedures for assessing the fracture strength of a protective paint coating of any thickness on a steel substrate of thickness not less than 10 mm. The procedures given in this part of ISO 16276 are based on methods used with different types of pull-off test equipment. The results obtained using such different types of equipment are not comparable.
This part of ISO 16276 also specifies suitable equipment and defines inspection areas, sampling plans and acceptance/rejection criteria.
It does not give any values of the fracture strength of different protective paint coatings.
Korrosionsschutz von Stahlbauten durch Beschichtungssysteme - Beurteilung der Adhäsion/Kohäsion (Haftfestigkeit) einer Beschichtung und Kriterien für deren Annahme - Teil1: Abreißversuch (ISO/DIS 16276-1:2024)
Dieser Teil von ISO 16276 legt Verfahren zum Bewerten der Haftfestigkeit eines Beschichtungssystems beliebiger Schichtdicke auf einem mindestens 10 mm dicken Stahlsubstrat fest. Die in diesem Teil von ISO 16276 angegebenen Verfahren basieren auf Prüfverfahren für unterschiedliche Typen von Abreißprüfgeräten. Die mit unterschiedlichen Typen von Abreißprüfgeräten erhaltenen Ergebnisse sind nicht zu vergleichen.
ANMERKUNG 1 Substrate mit weniger als 10 mm Dicke können geprüft werden, wenn sie durch die Sandwich Technik (siehe ISO 4624) oder die Art des Bauteiles (z. B. Doppel T Träger, Grundplatte) verstärkt werden. Ansonsten können Probenplatten mit mindestens 10 mm Dicke verwendet werden, die gleichzeitig mit dem Bauwerk beschichtet wurden, oder es wird nach ISO 16276 2 geprüft.
Dieser Teil von ISO 16276 ist nur anwendbar, wenn ein Wert für die Haftfestigkeit zusammen mit Typ und Hersteller des Gerätes festgelegt wird. Üblicherweise sind diese Angaben in den Vertragsunterlagen enthalten.
ANMERKUNG 2 Ein Wert für die Haftfestigkeit ist nur aussagefähig, wenn die Anforderungen an die Umgebungsbedingungen (siehe 6.4.2) eingehalten werden.
Dieser Teil von ISO 16276 legt die Anwendung geeigneter Geräte fest und definiert Inspektionsflächen, Messpläne sowie Kriterien für die Annahme/Ablehnung.
Er gibt keine Werte für die Haftfestigkeit von verschiedenen Beschichtungssystemen an.

L'ISO 16276-1:2007 spécifie des modes opératoires permettant d'évaluer la résistance à la rupture d'un système de peinture, quelle que soit son épaisseur, appliqué sur un subjectile en acier ayant une épaisseur au moins égale à 10 mm. Les modes opératoires figurant dans l'ISO 16276-1:2007 reposent sur des méthodes d'essai utilisant différents types de machines d'essai de traction. Les résultats obtenus sur ces différents types d'appareils d'essai ne sont pas comparables.
L'ISO 16276-1:2007 spécifie l'utilisation d'appareillages appropriés et définit les aires de contrôle, les plans d'échantillonnage et les critères d'acceptation/de rejet.
Elle ne donne aucune valeur de résistance à la rupture pour les différents systèmes de peinture.

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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO [had/had not] received notice of
(a) patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

Introduction
The main purpose of this part of ISO 16276 is to supplement the ISO 12944 series with regard to the field
assessment of, and acceptance criteria for, the adhesion/cohesion of a coating.
To comply with this part of ISO 16276, laboratory testing of panels might be required.
This part of ISO 16276 introduces the term “fracture strength” which includes both adhesion and cohesion.
Adhesion and cohesion are defined in ISO 4618, whereas the ISO 12944 series uses the term “adhesion” only.
NOTE This part of ISO 16276 is intended for the assessment of pull-off testing of paint coatings on steel structures
on site. ISO 4624 specifies a pull-off test for laboratory use, without instructions for interpretation of the results and
without acceptance or rejection criteria.
Fracture strength testing is normally destructive and therefore requires repair work, the extent of which
will depend on the specification and on the durability required of the protective paint coating.
An objective of this part of ISO 16276 is to provide uniformity in the assessment of the fracture strength of
a coating and to establish acceptance/rejection criteria for protective paint coatings. The method uses test
equipment based on the pull-off principle.
Protective paint systems which have poor adhesion/cohesion will normally fail at fracture strength values
significantly lower than the values quoted in the specification.
For a protective paint system with a particular fracture strength, a range of test values will be obtained
from different types of equipment.
Specifying test equipment that gives, for a particular fracture strength, the highest test values does not
necessarily indicate a higher durability for that protective paint system. Also, high test values for a particular
fracture strength do not necessarily indicate a high durability for that protective paint system.
