Why compare SN EN ISO 12944-5:2020 and ISO 12944-5:2019 vs ISO 12944-2
The comparison between SN EN ISO 12944-5:2020, ISO 12944-5:2019, and ISO 12944-2 is significant for professionals involved in corrosion protection and coating applications. Engineers, project managers, and quality assurance specialists are often faced with the challenge of determining which standard best suits their specific situations. This comparison addresses their needs by highlighting differences in scope, applicability, and guidance on protective paint systems.
How SN EN ISO 12944-5:2020 approaches the topic
SN EN ISO 12944-5:2020 focuses on the corrosion protection of steel structures through the use of protective paint systems. This standard categorizes environments based on their corrosivity and provides detailed guidance on the types of coatings suitable for various applications. It includes information on:
- Classification of environments for corrosion protection, helping users understand where specific coatings can be applied effectively.
- New construction and maintenance strategies, ensuring longevity and durability of protective systems.
- Types of coating materials such as alkyd resin coatings, acrylic resin coatings, and ethyl silicate coatings, providing a comprehensive overview of available options.
- Surface preparation grades which are critical for achieving optimal adhesion and performance of coatings.
Overall, this standard is essential for ensuring the correct application of protective measures against corrosion.
How ISO 12944-5:2019 vs ISO 12944-2 approaches the topic
ISO 12944-5:2019, similar to its successor, outlines guidelines for the protective paint systems for steel structures. However, ISO 12944-2 provides a broader framework for corrosion protection, focusing not only on paint systems but also on general principles for designing protective measures against corrosion in steel. Key aspects covered in ISO 12944-2 include:
- General requirements for corrosion protection, expanding beyond paint to include various protective strategies.
- Durability expectations of protective systems, giving users insights into the lifespan of different coatings.
- Certification mechanisms and compliance requirements, ensuring that users can easily navigate regulatory standards and certifications.
While both standards share similarities, ISO 12944-2 offers a more comprehensive overview of corrosion protection beyond just paint systems.
