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 16276-1:2007)

This part of ISO 16276 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. NOTE 1 Substrates of less than 10 mm in thickness can be tested if they are strengthened by the sandwich technique (see ISO 4624) or by the nature of the structure (e.g. I-beam or backing-plate). Otherwise, test panels with a thickness of at least 10 mm coated in the same way as the structure can be used, or the method specified ISO 16276-2 can be used. This part of ISO 16276 is only applicable if a fracture strength value is specified, together with the type of test equipment and the manufacturer of the equipment. Usually, this information is included in contract documentation.

Beschichtungsstoffe - Korrosionsschutz von Stahlbauten durch Beschichtungssysteme - Beurteilung der Adhäsion/Kohäsion (Haftfestigkeit) einer Beschichtung und Kriterien für deren Annahme - Teil 1: Abreißversuch (ISO 16276-1:2007)

Dieses Dokument legt Verfahren zum Bewerten der Haftfestigkeit eines Beschichtungssystems beliebiger Schichtdicke auf einem mindestens 10 mm dicken Stahlsubstrat fest. Die in dieser Norm 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 Profils (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 Teil 2 dieser Europäischen Norm geprüft.
Diese Europäische Norm gibt keine Werte für die Haftfestigkeit von verschiedenen Beschichtungssystemen an.
Diese Europäische Norm ist nur anwendbar, wenn ein Wert für die Haftfestigkeit zusammen mit Typ und Hersteller des Gerätes festgelegt werden. 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)eingehalten werden.
Diese Europäische Norm legt die Anwendung geeigneter Geräte fest und definiert Inspektionsflächen, Messpläne sowie Kriterien für die Annahme/Ablehnung.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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 document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 16276-1 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 139, Paints and varnishes, in collaboration with Technical Committee ISO/TC 35, Paints and
varnishes, Subcommittee SC 14, Protective paint systems for steel structures.
ISO 16276 consists of the following parts, under the general title 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
⎯ Part 2: Cross-cut testing and X-cut testing

ISO 16276-1:2007(E)
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.

INTERNATIONAL STANDARD ISO 16276-1:2007(E)

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
1 Scope
This part of ISO 16276 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.
NOTE 1 Substrates of less than 10 mm in thickness can be tested if they are strengthened by the sandwich technique
(see ISO 4624) or by the nature of the structure (e.g. I-beam or backing-plate). Otherwise, test panels with a thickness of
at least 10 mm coated in the same way as the structure can be used, or the method specified ISO 16276-2 can be used.
This part of ISO 16276 is only applicable if a fracture strength value is specified, together with the type of test
equipment and the manufacturer of the equipment. Usually, this information is included in contract
documentation.
NOTE 2 A value for the fracture strength is only meaningful if the requirements concerning the ambient conditions
(see 6.4.2) are met.
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.
