ISO12944 is the industry standard for corrosion protection of steel structures by protective paint systems. Originally released in 1998, the standard is put together by representatives from key countries and companies involved in the protection of steel structures to build a mutually beneficial standard.

Apr 16, 2020 · ISO 12944 addresses a protective paint system that can prevent corrosion in carbon or low-alloy structural steel. This coating system delays the corrosion of the metal because it can seal off the surface of the steel from the local microclimate that surrounds it and would otherwise generate rust.

health, safety and environmental protection, and guidelines for using ISO 12944 (all parts) for a given project. This document gives some terms and definitions related to paint systems in combination with guidance

Urban and industrial atmospheres with moderate sulfur dioxide levels. Coastal areas with low salinity. Each corrosivity class is sub-divided into three durabilities: The durabilities represent the approximate service time expectancy . A near-white blast cleaned metal surface.

International Standard ISO 12944-2 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 14, Corrosion protection of steel structures by protective paint systems. ISO 12944 consists of the following parts, under the general title Paints and varnishes — Corrosion protection of steel structures by protective

ISO 12944-1:2017 defines the overall scope of ISO 12944 (all parts). 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.

ISO 12944 is an international standard on corrosion protection of steel structures by protective paint systems. It consists of several parts: Part 1: General introduction; Part 2: Classification of environments; Part 3: Design considerations

This booklet summarises the main changes to ISO 12944 (revisions done in 2017 and 2018) relevant to paint applicators and specifiers. It is intended as a quick reference guide for people who already know and work with ISO 12944.

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.
