Paints and varnishes - Corrosion protection of steel structures by protective paint systems - Part 5: Protective paint systems (ISO 12944-5:2019)

This document describes the types of paint and paint system commonly used for corrosion protection of steel structures.
It also gives guidelines for the selection of paint systems available for different environments (see ISO 12944‑2) except for corrosivity category CX and category Im4 as defined in ISO 12944‑2 and different surface preparation grades (see ISO 12944‑4), and the durability grade to be expected (see ISO 12944‑1).

Beschichtungsstoffe - Korrosionsschutz von Stahlbauten durch Beschichtungssysteme - Teil 5: Beschichtungssysteme (ISO 12944-5:2019)

Dieses Dokument beschreibt die für den Korrosionsschutz von Stahlbauten allgemein verwendeten Arten von Beschichtungsstoffen und Beschichtungssystemen.
Es gibt außerdem eine Anleitung für die Auswahl von Beschichtungssystemen, für verschiedene Umgebungs-bedingungen (siehe ISO 12944-2), mit Ausnahme der Korrosivitätskategorie CX und der Kategorie Im4 nach ISO 12944-2 und verschiedener Oberflächenvorbereitungsgrade (siehe ISO 12944-4), und die zu erwartende Schutzdauer (siehe ISO 12944-1).

Peintures et vernis - Anticorrosion des structures en acier par systèmes de peinture - Partie 5: Systèmes de peinture (ISO 12944-5:2019)

Le présent document décrit les types de peinture et de systèmes de peinture couramment utilisés pour la protection contre la corrosion des structures en acier.
Il fournit également des lignes directrices pour le choix de systèmes de peinture adaptés aux différents environnements (voir l'ISO 12944-2), excepté les catégories de corrosivité CX et la catégorie Im4 telles que définies dans l'ISO 12944-2, les différents degrés de préparation de surface (voir l'ISO 12944-4) et le niveau de durabilité attendu (voir l'ISO 12944-1).

Barve in laki - Protikorozijska zaščita jeklenih konstrukcij z zaščitnimi premaznimi sistemi - 5. del: Zaščitni premazni sistemi (ISO 12944-5:2019)

V tem dokumentu so opisane vrste barv in premaznih sistemov, ki so pogosto uporabljeni za protikorozijsko zaščito jeklenih konstrukcij. Podane so tudi smernice za izbiro premaznih sistemov, ki so na voljo za različna okolja (glej ISO 12944-2), razen za korozijsko kategorijo CX in kategorijo Im4, kot je določeno v standardu ISO 12944-2, in različne stopnje priprave površine (glej ISO 12944-4), ter določena je pričakovana stopnja trajnosti (glej ISO 12944-1).
