ISO 12944-2:2017 - Classification of Environments for Corrosion Protection
ISO 12944-2:2017 serves as a critical standard in the paint and color industries, focusing on corrosion protection for steel structures. It delineates various environments that can impact the integrity and longevity of these structures. Understanding and adhering to this standard is vital for compliance and audit readiness, ensuring that protective paint systems are appropriately selected based on the corrosivity of the surroundings.
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.

Best practices at a glance
This section introduces a checklist of best practices that align with the clauses of SN EN ISO 12944-2:2018. These practices cover essential aspects of corrosion protection, from understanding environmental classifications to implementing the right protective measures, ensuring comprehensive compliance with the standard and enhancing overall structural integrity.
=== SECTION 2 ===
The practices
-
Understand corrosion categories: Familiarize yourself with the atmospheric-corrosivity categories defined in ISO 12944-2:2017. This understanding is crucial for selecting appropriate protective paint systems, as different environments pose varying levels of risk to steel structures. (Refer to Clause 4)
-
Conduct regular environmental assessments: Regularly assess the environments in which your steel structures operate. This practice ensures that any changes in environmental conditions are accounted for, allowing timely adjustments to protective strategies. (Refer to Clause 5)
-
Select protective paints based on environment: Choose protective paint systems that correlate with the categorized environment. This selection mitigates the risk of premature corrosion and structural failure, adhering to the recommendations provided in the standard. (Refer to Clause 6)
-
Document corrosion assessments: Keep thorough documentation of all corrosion assessments and environmental classifications. This practice not only aids in compliance but also serves as a valuable resource during audits and evaluations. (Refer to Clause 7)
-
Train personnel on corrosion risks: Ensure that employees are trained on the significance of corrosion risks and the importance of following ISO 12944-2:2017 guidelines. Proper training enhances awareness and adherence to best practices. (Refer to Clause 8)
-
Implement a monitoring program: Establish a monitoring program to track the condition of protective coatings and detect early signs of corrosion. This ongoing vigilance is essential for maintaining the integrity of steel structures. (Refer to Clause 9)
-
Review and update protective strategies regularly: Regularly review and update your protective strategies to align with any new findings or changes in environmental conditions. Staying proactive is key to long-term corrosion protection. (Refer to Clause 10)
-
Engage with certified professionals: Collaborate with certified professionals who specialize in corrosion protection and the ISO standards. Their expertise can guide effective implementation and compliance efforts. (Refer to Clause 11)
