Paints and varnishes - Corrosion protection of steel structures by protective paint systems - Part 2: Classification of environments (ISO 12944-2:2017)

ISO 12944-2:2017 deals with the classification of the principal environments to which steel structures are exposed, and the corrosivity of these environments. ISO 12944-2:2017
-      defines atmospheric-corrosivity categories, based on mass loss (or thickness loss) by standard specimens, and describes typical natural atmospheric environments to which steel structures are exposed, giving advice on the estimation of the corrosivity,
-      describes different categories of environment for structures immersed in water or buried in soil, and
-      gives information on some special corrosion stresses that can cause a significant increase in corrosion rate or place higher demands on the performance of the protective paint system.
The corrosion stresses associated with a particular environment or corrosivity category represent one essential parameter governing the selection of protective paint systems.

Beschichtungsstoffe - Korrosionsschutz von Stahlbauten durch Beschichtungssysteme - Teil 2: Einteilung der Umgebungsbedingungen (ISO 12944-2:2017)

Dieses Dokument beschreibt die häufigsten Umgebungsbedingungen, denen Stahlbauten ausgesetzt sind, und nimmt eine Einteilung dieser Umgebungsbedingungen anhand ihrer Korrosivität vor. Dieses Dokument enthält
—   eine Aufstellung von Kategorien atmosphärischer Korrosivität basierend auf dem Massenverlust (beziehungsweise Dickenverlust) von Standardproben mit Beschreibung typischer natürlicher atmosphärischer Umgebungsbedingungen, denen Stahlbauten ausgesetzt sind, wobei Hinweise zur Bestimmung der Korrosivität gegeben werden,
—   eine Beschreibung der verschiedenen Kategorien von Umgebungsbedingungen für Stahlbauten, die sich in Wasser oder Erdreich befinden und
—   Informationen zu besonderen Korrosionsbelastungen, die Korrosion wesentlich befördern oder eine höhere Leistungsfähigkeit des Beschichtungssystems erforderlich machen können.
Die mit einer bestimmten Umgebung oder Korrosivitätskategorie verbundenen Korrosionsbelastungen sind ein wesentlicher Parameter für die Auswahl des Beschichtungssystems.

Peintures et vernis - Anticorrosion des structures en acier par systèmes de peinture - Partie 2: Classification des environnements (ISO 12944-2:2017)

ISO 12944-2:2017 traite de la classification des principaux environnements auxquels sont exposées les structures en acier peintes et de la corrosivité de ces environnements. Le présent document
-      définit les catégories de corrosivité atmosphérique, basées sur la perte de masse (ou la perte d'épaisseur) au moyen d'éprouvettes standard, et décrit les environnements atmosphériques naturels types auxquels sont exposées les structures en acier, en donnant des conseils pour l'estimation de la corrosivité,
-      décrit différentes catégories d'environnement pour les structures immergées ou enterrées, et
-      fournit des informations sur certaines contraintes de corrosion particulières, susceptibles d'augmenter de façon significative la vitesse de corrosion ou de nécessiter une plus grande performance du système de peinture.
Des contraintes de corrosion associées à un environnement particulier ou à une catégorie de corrosivité représentent un paramètre essentiel pour le choix de systèmes de peinture.

Barve in laki - Protikorozijska zaščita jeklenih konstrukcij z zaščitnimi premaznimi sistemi - 2. del: Klasifikacija okoljskih pogojev (ISO 12944-2:2017)

ISO 12944-2:2017 obravnava klasifikacijo glavnih okoljskih pogojev, ki so jim izpostavljene jeklene konstrukcije, in korozivnost teh pogojev. ISO 12944-2:2017
- opredeljuje kategorije atmosferske korozivnosti na podlagi izgube mase (ali debeline) s standardnimi vzorci in opisuje običajne naravne atmosferske okoljske pogoje, ki so jim izpostavljene jeklene konstrukcije, ter podaja nasvete glede vrednotenja korozivnosti;
- opisuje različne kategorije okoljskih pogojev za konstrukcije, potopljene v vodo ali zakopane v zemljo; in
- podaja informacije o nekaterih posebnih korozijskih obremenitvah, ki lahko povzročijo znatno povečanje stopnje korozije ali postavijo višje zahteve glede učinkovitosti zaščitnega premaznega sistema.
Korozijske obremenitve, povezane z določenimi okoljskimi pogoji ali kategorijo korozivnosti, predstavljajo enega od osnovnih parametrov, ki vplivajo na izbiro zaščitnih premaznih sistemov.
