Understanding SN EN ISO 12944-2:2018 for Corrosion Protection
SN EN ISO 12944-2:2018
Beschichtungsstoffe - Korrosionsschutz von Stahlbauten durch Beschichtungssysteme - Teil 2: Einteilung der Umgebungsbedingungen (ISO 12944-2:2017)
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.

What SN EN ISO 12944-2:2018 covers
SN EN ISO 12944-2:2018 provides a systematic classification of environments that may impact steel structures, focusing on atmospheric conditions as well as conditions related to water immersion and soil burial. The standard categorizes environments based on their corrosivity, assessing potential damage through mass loss or thickness loss observed in standardized specimens. It outlines various corrosivity categories and identifies typical atmospheric environments, helping professionals estimate corrosion risks for steel structures. Furthermore, it addresses special corrosion stresses that can elevate corrosion rates and influence the selection of protective paint systems. Notably, it does not cover specific application methodologies for protective coatings, which are addressed in other parts of the ISO 12944 series.

Who needs to comply with SN EN ISO 12944-2:2018
This standard is vital for a wide range of stakeholders within the Paint & Color Industries. Key audiences include manufacturers of protective coatings, civil engineers, architects, and asset managers responsible for steel structures across various sectors such as construction, transportation, and infrastructure. Organizations of all sizes, from small to large enterprises, need to ensure compliance to maintain the integrity of their steel structures and protect them against corrosion. Additionally, regulatory bodies and quality assurance professionals involved in material specifications and compliance audits will find this standard relevant for ensuring quality and safety in their projects.
=== SECTION 3 ===
Key requirements
- Corrosivity Classification: The standard classifies environments based on corrosivity, allowing for informed decisions regarding protective paint systems.
- Mass Loss Measurement: It defines how to measure mass loss or thickness loss in standard specimens to evaluate corrosion rates effectively.
- Environmental Categories: It categorizes environments for structures above ground, immersed in water, or buried in soil, each with distinct corrosivity assessments.
- Special Corrosion Stresses: The standard mentions specific corrosion stresses that can affect corrosion rates and coating performance, guiding the selection of appropriate protective systems.
- Estimation Guidance: It provides methodologies for estimating corrosivity based on environmental conditions, aiding in proactive maintenance planning.
These requirements are typically audited through comprehensive assessments, ensuring adherence to the classification and protective measures outlined in the standard.

How to implement SN EN ISO 12944-2:2018
Implementing SN EN ISO 12944-2:2018 involves a series of strategic steps to ensure compliance and effective corrosion protection. Organizations should begin with a gap analysis to identify current practices against standard requirements. This is followed by the development of appropriate documentation that details the corrosion protection measures and paint systems in use. Training sessions should then be organized to educate employees about the standard and its implications on their work. An internal audit should be conducted to assess adherence to the standard, followed by a certification audit to validate compliance. This structured approach not only aligns practices with the standard but also enhances overall quality management in corrosion protection.
