ISO 12944-5:2019 Certification Process Explained
Purpose and objectives
The ISO 12944-5:2019 standard provides guidelines for the corrosion protection of steel structures through protective paint systems. Its primary objective is to ensure that coatings are selected and applied effectively to withstand various environmental conditions, ultimately enhancing the durability and longevity of steel structures. By establishing a uniform set of requirements, the standard aims to assist manufacturers, contractors, and end-users in understanding the best practices for coating application and maintenance. This ensures that protective systems are both efficient and compliant with international standards.
Scope: who must comply
The SN EN ISO 12944-5:2020 standard applies to a broad range of industries that utilize steel structures, particularly in sectors such as construction, manufacturing, and infrastructure. Companies involved in the production and application of protective paint systems, including those in the Paint & Color Industries, must adhere to these guidelines. Typical profiles include manufacturers of alkyd and acrylic resin coatings, contractors specializing in corrosion protection, and maintenance professionals responsible for the upkeep of steel structures in environments prone to corrosion.
How SN EN ISO 12944-5:2020 relates to other standards
The ISO 12944-5:2019 standard is part of a comprehensive family of ISO 12944 standards that address various aspects of corrosion protection. Related standards include:
- ISO 12944-1: This part outlines the general principles and definitions concerning corrosion protection.
- ISO 12944-2: This section details classification of environments based on corrosivity categories, which is essential for the correct application of protective systems.
- ISO 12944-3: This part provides information on the selection of coating systems based on the environmental conditions and intended use of the steel structure.
Revision history and current status
The current revision of the standard is SN EN ISO 12944-5:2020, published by the Swiss Normen-Vereinigung (SNV). This revision reflects updates aimed at improving clarity and addressing emerging technologies in coating materials. The most recent changes include enhanced guidelines on the expected durability of protective systems and refined surface preparation grades, ensuring that compliance with ISO 12944-5:2019 is aligned with contemporary practices in corrosion protection.

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).
