Paints and varnishes - Corrosion protection of steel structures by protective paint systems - Part 8: Development of specifications for new work and maintenance (ISO 12944-8:2017)
ISO 12944-8:2017 covers the development of specifications for corrosion protection of steel structures using protective paint systems. It relates to new work and maintenance in the workshop or on site and is also applicable to the corrosion protection of individual components. ISO 12944-8:2017 covers the corrosion protection of steel structures exposed to different corrosion stresses by environments such as indoors, open-air and immersion in water or burial in soil, as well as special stresses, due for example, to medium or high temperatures. The need for different durability ranges is considered.
Steel surfaces that have been hot-dip-galvanized, metal-sprayed, zinc-electroplated or sherardized, and previously painted steel surfaces, are also covered by ISO 12944-8:2017.
In ISO 12944-8:2017, reference areas for assessing the quality of the corrosion protection work and the performance of the protective paint systems used are dealt with. ISO 12944-8:2017 provides detailed flow charts for planning new work and maintenance, which are taken into account when writing a specification.
ISO 12944-8:2017 can also be used as a guide if extreme corrosion stresses or high temperatures occur, or if the protective paint systems are to be used on other substrates, such as non-ferrous metals or concrete, to define suitable specifications.
Beschichtungsstoffe - Korrosionsschutz von Stahlbauten durch Beschichtungssysteme - Teil 8: Erarbeiten von Spezifikationen für Erstschutz und Instandsetzung (ISO 12944-8:2017)
In diesem Dokument wird die Erarbeitung von Spezifikationen für den Korrosionsschutz von Stahlbauten durch Beschichtungssysteme behandelt. Es bezieht sich auf Erstschutz und Instandsetzung, im Werk oder auf der Baustelle, und ist auch auf den Korrosionsschutz von einzelnen Bauteilen anwendbar. In diesem Dokument werden der Korrosionsschutz von Stahlbauten, die unterschiedlichen Korrosionsbelastungen durch Umgebungen, wie z. B. in Innenräumen, im Freien sowie in Wasser oder im Erdreich ausgesetzt sind, sowie Sonderbelastungen, z. B. durch mittlere oder hohe Temperaturen, behandelt. Die Notwendigkeit unterschiedlicher Zeitspannen für die Schutzdauer wird berücksichtigt.
Stahloberflächen, die feuerverzinkt, thermisch gespritzt, galvanisch verzinkt oder sherardisiert wurden sowie bereits zuvor beschichtete Stahloberflächen werden in diesem Dokument ebenfalls erfasst.
In diesem Dokument werden Kontrollflächen zum Bewerten der Qualität der Korrosionsschutzarbeiten und der Leistungsfähigkeit der angewendeten Beschichtungssysteme behandelt. Dieses Dokument enthält detaillierte Fließdiagramme für die Planung von Erstschutz- und Instandsetzungsarbeiten, die beim Erstellen einer Spezifikation berücksichtigt werden sollten.
Dieses Dokument kann auch als Leitfaden zur Festlegung geeigneter Spezifikationen angewendet werden, wenn außergewöhnliche Korrosionsbelastungen oder äußerst hohe Temperaturen auftreten oder wenn die Beschichtungssysteme für andere Untergründe, z. B. Nichteisenmetalle oder Beton, zu verwenden sind.
Peintures et vernis - Anticorrosion des structures en acier par systèmes de peinture - Partie 8: Développement de spécifications pour les travaux neufs et de maintenance (ISO 12944-8:2017)
L'ISO 12944-8 :2017 couvre le développement de spécifications relatives à la protection contre la corrosion des structures en acier au moyen de systèmes de peinture anticorrosion. Elle s'applique aux travaux neufs et à la maintenance en atelier ou sur site, ainsi qu'à la protection contre la corrosion des éléments individuels. L'ISO 12944-8 :2017 couvre la protection anticorrosion des structures en acier exposées à différentes contraintes de corrosion dues à l'environnement ? intérieur, extérieur, immersion dans l'eau ou enfouissement dans le sol ? ainsi qu'à des contraintes spéciales, qu'elles soient dues à des températures moyennes ou élevées. Il prend en considération l'existence de besoins différents en matière de durabilité.
L'ISO 12944-8 :2017 traite également des subjectiles d'acier qui ont été galvanisés au trempé à chaud, revêtus de métal par projection à chaud, électrozingués ou shérardisés, ainsi que des aciers préalablement peints.
Il traite par ailleurs des surfaces de référence permettant d'évaluer la qualité de la protection contre la corrosion et les performances des systèmes de peinture anticorrosion utilisés. L'ISO 12944-8 :2017 propose des logigrammes de planning pour des travaux neufs et de maintenance pour l'élaboration d'une spécification.
L'ISO 12944-8 :2017 peut également servir de guide pour définir des spécifications adaptées en cas de contraintes de corrosion extrêmes ou de températures élevées ou lorsque les systèmes de peinture anticorrosion sont utilisés sur d'autres subjectiles, comme des métaux non-ferreux ou du béton.
Barve in laki - Protikorozijska zaščita jeklenih konstrukcij z zaščitnimi premaznimi sistemi - 8. del: Priprava specifikacij za novogradnje in vzdrževanje (ISO 12944-8:2017)
Ta dokument zajema pripravo specifikacij za protikorozijsko zaščito jeklenih konstrukcij z uporabo zaščitnih premaznih sistemov. Nanaša se na novogradnje in vzdrževanje v delavnici ali na mestu uporabe konstrukcije in se uporablja tudi za protikorozijsko zaščito posameznih sestavnih delov. Ta dokument zajema protikorozijsko zaščito jeklenih konstrukcij, izpostavljenih različnim korozijskim obremenitvam (npr. v zaprtih prostorih, na prostem in pri potopu v vodo ali zakopanosti v zemljo) ter posebnim obremenitvam (npr. zaradi izpostavljenosti srednje visokim ali visokim temperaturam). Upoštevana je potreba po različnih razponih trajnosti.
V tem dokumentu so zajete tudi jeklene površine, ki so bile vroče galvanizirane, kovinsko brizgane, galvanizirane s cinkom ali šeradirane, in predhodno premazane jeklene površine.
V tem dokumentu so obravnavana referenčna območja za ocenjevanje kakovosti ukrepov protikorozijske zaščite in učinkovitosti zaščitnih premaznih sistemov. Ta dokument vključuje podrobne diagrame poteka za načrtovanje novogradenj in vzdrževanja, ki se upoštevajo pri pripravi specifikacije.
Ta dokument se lahko uporablja tudi kot vodilo, če se pojavijo ekstremne korozijske obremenitve ali visoke temperature ali če se zaščitni premazni sistemi uporabljajo za druge podlage, kot so neželezne kovine ali beton, za določitev ustreznih specifikacij.

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

Introduction
Unprotected steel in the atmosphere, in water and in soil is subjected to corrosion that can lead to
damage. Therefore, to avoid corrosion damage, steel structures are normally protected to withstand
the corrosion stresses to which they will be subjected during the service life required of the structure.
There are different ways of protecting steel structures from corrosion. ISO 12944 (all parts) deals with
protection by paint systems and covers, in the various parts, all features that are important in achieving
adequate corrosion protection. Additional or other measures are possible but require particular
agreement between the interested parties.
In order to ensure effective corrosion protection of steel structures, owners of such structures, planners,
consultants, companies carrying out corrosion protection work, inspectors of protective coatings
and manufacturers of coating materials need to have at their disposal state-of-the-art information in
concise form on
