Paints and varnishes - Corrosion protection of steel structures by protective paint systems - Part 9: Protective paint systems and laboratory performance test methods for offshore and related structures (ISO 12944-9:2018)

This International Standard deals with performance requirements for protective paint systems for offshore and related structures (i.e. those exposed to the marine atmosphere, as well as those immersed in sea or brackish water). Such structures are exposed to environments of corrosivity category CX (offshore) and immersion category Im4 as defined in ISO 12944-2, with special stresses as given in 4.3 and Annex B of ISO 12944-2:1998. ISO 12944-9 can also be used for other structures, provided that the paints or protective paint systems selected comply with this International Standard.
This International Standard places emphasis on high-durability paint systems, with the aim of minimizing maintenance and hence reducing safety considerations and environmental impact.
The temperature range applicable for these paint systems is considered to be between -20 °C and +120 °C, and the performance testing is aimed at verifying suitability of the paint systems for this temperature range. The use of paint systems outside this temperature range shall be subject to agreement by the end user. Such agreement may include testing at the applicable temperatures.
The paint systems for submerged service (Im4) are aimed at ambient operating temperatures up to a maximum of 50 °C. For higher operating temperatures, specific evaluation and performance documentation is needed. The selection of performance requirements should be considered in conjunction with the cathodic protection design parameters.

Beschichtungsstoffe - Korrosionsschutz von Stahlbauten durch Beschichtungssysteme - Teil 9: Beschichtungssysteme und Leistungsprüfverfahren im Labor für Bauwerke im Offshorebereich (ISO 12944-9:2018)

Diese Internationale Norm behandelt die Leistungsanforderungen an Beschichtungssysteme für Bauwerke im Offshorebereich (d. h. solche, die Meeresatmosphäre ausgesetzt sind, sowie im Meer oder in Brackwasser eingetauchte Beschichtungssysteme). Derartige Bauwerke sind Umgebungen der Korrosivitätskategorie CK (Offshore) und der Immersionskategorie Im4 ausgesetzt, wie in ISO 12944 2 festgelegt.
Diese Internationale Norm behandelt Bauwerke aus Kohlenstoffstahl, die Oberflächen Cd/Bi Cr und Zn/Bi Cr deckt sie nicht ab. Auch Oberflächen unter Dämmungen oder Beton werden nicht abgedeckt.
Diese Internationale Norm hebt Beschichtungssysteme mit langer Schutzdauer mit dem Ziel hervor, die Instandsetzung auf ein Mindestmaß zu verringern und dadurch Sicherheitsüberlegungen und Um¬welt-belastungen zu reduzieren.
Der anwendbare Temperaturbereich für diese Beschichtungssysteme liegt zwischen −20 °C und +80  C und die Leistungsprüfung zielt auf die Eignungsprüfung der Beschichtungssysteme für diesen Tem¬pe¬ra¬tur-bereich ab. Die Nutzung der Beschichtungssysteme außerhalb dieses Temperaturbereichs muss durch den End¬anwender vereinbart werden. Eine solche Vereinbarung darf eine Prüfung bei den maßgeblichen Temperaturen einschließen.
Die Beschichtungssysteme für Beanspruchungen durch Eintauchen (Im4) zielen auf Betriebstemperaturen der Umgebung bis maximal 50 °C ab. Bei höheren Betriebstemperaturen sind spezielle Bewertungen und Leistungsdokumentationen nötig. Die Auswahl der Leistungsanforderungen sollte in Verbindung mit den Gestaltungsparametern des kathodischen Schutzes betrachtet werden.
Diese Internationale Norm schließt Folgendes ein:
—   die Prüfverfahren zur Bestimmung der Zusammensetzung der einzelnen Bestandteile des Beschichtungssystems;
—   die Leistungsprüfverfahren des Labors zur Bewertung der voraussichtlichen Schutzdauer des Beschichtungssystems;
—   die Kriterien zur Beurteilung der Ergebnisse der Leistungsprüfungen.
Diese Internationale Norm behandelt die Anforderungen an neue Arbeiten und alle vor der Inbetriebnahme erforderlichen Ausbesserungen. Sie darf auch in Bezug auf die Instandhaltung angewendet werden, wenn eine vollständige Erneuerung durchgeführt wird und das darunter liegende Metallsubstrat durch Strahlen vollständig freigelegt wurde (siehe 4.4).
Instandhaltung im Allgemeinen wird von dieser Norm nicht behandelt, wo zur Oberflächenbehandlung üblicherweise andere Verfahren als Strahlen angewendet werden.

ISO 12944-9:2018 traite des exigences de performance relatives aux systèmes de peinture anticorrosion pour la protection des structures offshore et structures associées (c'est-à-dire exposées à l'environnement marin ou immergées dans l'eau de mer ou l'eau saumâtre). Ces structures sont exposées à des environnements de catégorie de corrosivité CX (offshore) et de catégorie d'immersion Im4 telles que définies dans l'ISO 12944‑2.
ISO 12944-9:2018 décrit des systèmes de peinture pour une haute durabilité conformément à l'ISO 12944‑1.
ISO 12944-9:2018 traite des structures en acier au carbone et ne traite pas des surfaces de type Cd/Bi Cr et Zn/Bi Cr. Il ne s'applique pas non plus aux surfaces recouvertes d'isolant ou de béton.
ISO 12944-9:2018 s'applique aux systèmes de peinture prévus pour une plage de température d'utilisation entre ?20 °C et +80 °C et les essais de performance ont pour objectif de vérifier l'adéquation des systèmes de peinture à cette plage de température.
ISO 12944-9:2018 s'applique aux systèmes de peinture employés pour un service en immersion (Im4) qui sont destinés à des températures ambiantes de service pouvant aller jusqu'à une température maximale de 50 °C.
ISO 12944-9:2018 spécifie:
-      les méthodes d'essai à utiliser pour déterminer la composition des différents composants du système de peinture anticorrosion;
-      les méthodes d'essai de performance en laboratoire afin d'évaluer la durabilité probable du système de peinture anticorrosion;
-      les critères à appliquer pour évaluer les résultats des essais de performance.
ISO 12944-9:2018 couvre les exigences relatives aux travaux neufs et aux éventuelles réparations nécessaires avant la mise en service. Il peut également être utilisé dans le cadre de la maintenance lorsqu'une rénovation complète est effectuée et que le subjectile métallique sous-jacent est entièrement mis à nu par un décapage par projection d'abrasif.
ISO 12944-9:2018 ne traite pas de la maintenance en général lorsque des méthodes de préparation de surface autres que le décapage par projection d'abrasif sont concernées.
ISO 12944-9:2018 traite des structures en acier d'une épaisseur d'au moins 3 mm, qui ont fait l'objet d'un calcul de résistance approuvé au stade de la conception.
Les structures suivantes ne sont pas couvertes par le présent document:
-      les structures en acier inoxydable ainsi que celles construites en cuivre, en titane ou en aluminium, ou leurs alliages;
-      les câbles en acier;
-      les structures enterrées;

Barve in laki - Protikorozijska zaščita jeklenih konstrukcij z zaščitnimi premaznimi sistemi - 9. del: Zaščitni premazni sistemi in laboratorijske preskusne metode za konstrukcije na morju in sorodne konstrukcije (ISO 12944-9:2018)

Ta mednarodni standard obravnava zahteve glede učinkovitosti zaščitnih premaznih sistemov za konstrukcije na morju in sorodne konstrukcije (tiste, ki so izpostavljene morskemu ozračju, pa tudi tiste, ki so potopljene v morsko ali slano vodo). Takšne konstrukcije so izpostavljene okolju kategorije korozivnosti CX (na morju) in imerzijske kategorije Im4, kot je opredeljeno v standardu ISO 12944-2, s posebnimi obremenitvami iz točke 4.3 in dodatka B standarda ISO 12944-2:1998. ISO 12944-9 se lahko uporablja tudi za druge konstrukcije, če so barve ali zaščitni premazi izbrani v skladu s tem mednarodnim standardom. Ta mednarodni standard daje poudarek na zelo vzdržljive sisteme zaščitnih premazov, ki zagotavljajo manj vzdrževanja konstrukcij, povzročajo manj varnostnih tveganj in imajo manjši vpliv na okolje. Temperaturno območje, ki velja za te sisteme premazov, je med –20 °C in 120 °C, preskušanje zmogljivosti pa je namenjeno preverjanju primernosti sistemov premazov za to temperaturno območje. Za uporabo premaznih sistemov zunaj tega temperaturnega območja se je treba dogovoriti s končnim uporabnikom. Tak dogovor lahko vključuje tudi preskušanje pri takih temperaturah. Premazni sistemi za potopno uporabo (Im4) so namenjeni delovnim temperaturam okolja do največ 50 °C. Za višje temperature sta potrebni posebna evalvacija in izvedbena dokumentacija. Izbor zahtev glede zmogljivosti naj bi upoštevali v povezavi s parametri katodne zaščite.

ISO 12944-9:2018(E)
Introduction

Unprotected steel in the atmosphere, in water and in soil is subject 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 corrosion protection by paint systems. It is vital that such information is as complete as

possible, unambiguous and easily understandable to avoid difficulties and misunderstandings between

the parties concerned with the practical implementation of protection work.

ISO 12944 (all parts) is intended to give this information in the form of a series of instructions. It is

written for those who have some technical knowledge. It is also assumed that the user of ISO 12944 (all

parts) is familiar with other relevant International Standards, in particular those dealing with surface

preparation.

Although ISO 12944 (all parts) does not deal with financial and contractual questions, attention is

drawn to the fact that, because of the considerable implications of inadequate corrosion protection,

non-compliance with requirements and recommendations given in this document may result in serious

financial consequences.

ISO 12944-1 defines the overall scope of ISO 12944. It gives some basic terms and definitions and a

general introduction to the other parts of ISO 12944. Furthermore, it includes a general statement on

health, safety and environmental protection, and guidelines for using ISO 12944 (all parts) for a given

project.

Offshore and related structures require specific attention in order to be able to withstand the severe

corrosion stresses to which they are exposed during their service life and to minimize the risk of

failures that would impact safety, operating costs or capital cost.

In order to establish sufficient corrosion protection and ensure optimum performance of the coating,

it is necessary to specify the requirements for the protective paint system(s) along with the relevant

laboratory performance tests to assess its (their) likely durability.

In order to achieve the same performance as indicated by testing, proper surface preparation and

application of the paint is essential. Close attention needs to be given to the execution of the work.

This document places emphasis on high-durability paint systems, with the aim of minimizing

maintenance and hence reducing safety considerations and environmental impact.

Part 9:
Protective paint systems and laboratory performance test
methods for offshore and related structures
1 Scope

This document specifies the performance requirements for protective paint systems for offshore and

related structures (i.e. those exposed to the marine atmosphere, as well as those immersed in sea or

brackish water). Such structures are exposed to environments of corrosivity category CX (offshore) and

immersion category Im4 as defined in ISO 12944-2.

This part of ISO 12944 describes paint systems for high durability according to ISO 12944-1.

This document is applicable to structures made of carbon steel and does not cover Cd/Bi Cr and Zn/Bi

Cr surfaces. It is not applicable to surfaces under insulation or concrete.

This document is applicable for paint systems intended for a service temperature range between −20 °C

and +80 °C, and the performance testing is aimed at verifying suitability of the paint systems for this

temperature range.

This document is applicable for paint systems for submerged service (Im4) which are intended for

ambient operating temperatures up to a maximum of 50 °C.
This document specifies:

— the test methods to be used to determine the composition of the separate components of the

protective paint system;

— the laboratory performance test methods for the assessment of the likely durability of the protective

paint system;
— the criteria to be used to evaluate the results of performance tests.

This document covers the requirements for new work and any repairs necessary before start-up. It can

also be used in relation to maintenance where complete refurbishment is carried out and the underlying

metal substrate is completely exposed by abrasive blast-cleaning.

It does not address maintenance in general where methods of surface preparation other than abrasive

blast-cleaning are typically used.

This document deals with structures, made of carbon steel of not less than 3 mm thickness, which are

designed using an approved strength calculation.
The following are not covered by this document:

— structures built of stainless steel as well as those built of copper, titanium or aluminium or their alloys;

— steel cables;
— buried structures;
— pipelines;
