Paints and varnishes - Corrosion protection by protective paint systems - Assessment of porosity in a dry film (ISO 29601:2011)
This document specifies procedures for detecting the presence of porosity (discontinuity) in a protective paint system of any film thickness on a steel or other metallic substrate. The procedures given in this document are based on test methods for two different types of test equipment according to the dry film thickness. These procedures are only applicable for testing electrically non-conductive parts of a paint system.
This document specifies the use of appropriate equipment, defines inspection procedures and provides guidance for the interpretation of the results.
Beschichtungsstoffe - Korrosionsschutz von Stahlbauten durch Beschichtungssysteme - Beurteilung der Porosität einer trockenen Beschichtung (ISO 29601:2011)
Dieses Dokument legt Verfahren zur Feststellung von Porosität in Beschichtungssystemen jeder Schichtdicke für den Korrosionsschutz auf einem Stahlsubstrat oder anderen Substraten aus Metall fest. Die in diesem Dokument angegebenen Verfahren basieren auf Prüfverfahren, die je nach Trockenschichtdicke mit zwei unterschiedlichen Prüfgerätetypen arbeiten. Diese Verfahren sind nur für die Prüfung elektrisch nichtleitender Teile eines Beschichtungssystems anwendbar.
Dieses Dokument legt die Anwendung geeigneter Geräte fest, definiert Verfahren für die Inspektion und gibt Hinweise für die Angabe der Ergebnisse.
Die festgelegten Prüfverfahren werden hauptsächlich für neue Beschichtungen angewendet, sie können jedoch auch für Beschichtungen angewendet werden, die bereits in der Praxis gebraucht wurden. Dabei muss die Möglichkeit berücksichtigt werden, dass die Beschichtungen durch das Eindringen von Materialien, die in der Praxis mit ihnen in Kontakt gekommen sind, verletzt sein könnten.
Peintures et vernis - Anticorrosion par systèmes de peinture - Évaluation de la porosité d'un feuil sec (ISO 29601:2011)
L'ISO 29601:2011 spécifie des modes opératoires permettant de détecter l'existence de porosité dans un système de revêtement de peinture, quelle qu'en soit l'épaisseur, appliqué sur un subjectile en acier ou sur tout autre métal. Les modes opératoires fournis dans la présente Norme internationale sont basés sur des méthodes faisant appel à deux types d'équipement d'essai, le choix de l'équipement étant fonction de l'épaisseur du feuil sec. Ces modes opératoires ne s'appliquent qu'aux essais des couches électriquement non conductrices d'un système de peinture.
Les méthodes d'essai spécifiées sont destinées principalement aux revêtements neufs mais peuvent aussi être employées pour les revêtements déjà mis en service. Dans ce dernier cas, il est important de garder à l'esprit le fait que des substances en contact avec le revêtement ont pu y pénétrer pendant la période en service.
Barve in laki - Korozijska zaščita z zaščitnimi premaznimi sistemi - Ocenjevanje poroznosti suhega filma (ISO 29601:2011)
Ta mednarodni standard določa postopke za odkrivanje poroznosti zaščitnega premaznega sistema kakršne koli debeline na jeklu ali drugem kovinskem substratu. Postopki, navedeni v tem mednarodnem standardu, temeljijo na metodah, ki uporabljajo dve različni vrsti preskusne opreme, izbira opreme pa je odvisna od debeline suhega filma. Ti postopki veljajo le za preskušanje električno neprevodnih delov premaznega sistema. Opredeljene preskusne metode so v glavnem namenjene uporabi z novimi premazi, lahko pa se uporabljajo za premaze, ki se že nekaj časa uporabljajo. V zadnjem primeru je treba upoštevati, da so premaz lahko predrle snovi, ki so bile med uporabo z njim v stiku.

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 29601 was prepared by the European Committee for Standardization (CEN) in collaboration with ISO
Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 14, Protective paint systems for
steel structures, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna
Agreement).

Introduction
This International Standard supplements the ISO 12944 series (see the Bibliography) with regard to the
detection of porosity in a dry film. If specified or agreed, the standard can also be used for other applications.
The objective of this International Standard is to achieve uniformity of practice for the detection of porosity in a
dry film. The methods chosen entail the detection of porosity using one of two types of equipment, a low-
voltage pinhole detector or a high-voltage spark tester.
This International Standard complements ISO 19840, which concerns the measurement of the thickness of
dry films on rough surfaces, and ISO 16276-1 and ISO 16276-2, which concern the measurement of the
adhesion of a coating by pull-off testing (Part 1) and by cross-cut and X-cut testing (Part 2).

INTERNATIONAL STANDARD ISO 29601:2011(E)
Paints and varnishes — Corrosion protection by protective
paint systems — Assessment of porosity in a dry film
1 Scope
This International Standard specifies procedures for detecting the presence of porosity in a protective paint
system of any thickness on a steel or other metallic substrate. The procedures given in this International
Standard are based on methods using two different types of test equipment, the choice of equipment
depending on the dry film thickness. These procedures are only applicable to the testing of electrically non-
conductive parts of a paint system.
The test methods specified are mainly intended for use with new coatings, but can also be used for coatings
which have been in service for some time. In the latter case, it is important to bear in mind that the coating
might have been penetrated by substances in contact with the coating during service.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
porosity
presence of one or more discontinuities in a coating
2.2
discontinuity
hole, pit, pinhole, void, crack, thin spot, inclusion, contamination or other flaw in a coating that significantly
lowers the dielectric strength of the coating
NOTE Certain types of discontinuity can also be described as a holiday.
2.3
nominal dry film thickness
NDFT
dry film thickness specified for each coat or for the whole paint system
[ISO 19840:2004]
2.4
mean dry film thickness
arithmetic mean of all the individual dry film thicknesses in the inspection area
[ISO 19840:2004]
2.5
inspection area
designated area for inspection as defined in the specification
NOTE If inspection areas are not defined, the whole structure is a single inspection area.
