What is ISO 12944-4: 2018 ?

Title: Understanding and Adhering to ISO 12944-4: 2018 and EN ISO 12944-1: 2017: A Guide for Protective Coating on Steel Structures

Steel structures are often subjected to harsh environments, such as marine or industrial atmospheres, which can cause them to corrode and reduce their lifespan. To prevent this, paint systems are applied to the steel structures to provide protection and extend their lifespan. However, ensuring the quality and effectiveness of the paint systems is critical. ISO 12944-4: 2018 and EN ISO 12944-1: 2017 are two international standards that offer guidelines for the selection and implementation of protective coatings on steel structures.

Understanding ISO 12944-4: 2018:

ISO 12944-4: 2018 is an international standard that provides guidelines for the selection and specification of paint systems, surface preparation, application methods, and quality control measures for protective coatings on steel structures. The standard covers the entire lifecycle of the coating system, from the selection of the appropriate paint system to the performance criteria for each layer.

ISO 12944-4: 2018 offers valuable information on the corrosion resistance of the paint system, the environmental impact of the paint, and the performance criteria for the different layers of the coating system. It also provides guidance on the testing and measurement of the performance of the paint system.

The Importance of ISO 12944-4: 2018:

ISO 12944-4: 2018 plays a crucial role in ensuring the durability and effectiveness of protective coatings on steel structures. It ensures that the paint system is designed to meet the specific requirements of the corrosive environment, such as marine or industrial atmospheres, and that it is able to prevent corrosion for the expected service life of the structure.

ISO 12944-4: 2018 also provides essential guidance for coating manufacturers, contractors, inspectors, and end-users in selecting the appropriate paint system based on the corrosive environment. The standard ensures consistent quality and performance of paint systems, leading to enhanced safety, reduced maintenance costs, and increased asset value over time.

Understanding EN ISO 12944-1: 2017:

EN ISO 12944-1: 2017 is an international standard that provides guidelines for the corrosion protection of steel structures, with a focus on industrial environments. The standard outlines various methods of surface preparation, types of protective coatings, and application procedures to ensure the longevity and durability of steel structures.

The Purpose of EN ISO 12944-1: 2017:

The primary purpose of EN ISO 12944-1: 2017 is to offer a comprehensive approach to protecting steel structures from corrosion. It outlines various methods of surface preparation, types of protective coatings, and application procedures to ensure the longevity and durability of steel structures in different environments.

Key Guidelines and Recommendations:

ISO 12944-4: 2018 and EN ISO 12944-1: 2017 offer guidelines for selecting and implementing protective coatings on steel structures. The standard provides essential information on the corrosion resistance of the paint system, the environmental impact of the paint, and the performance criteria for each layer of the coating system.

To ensure the effectiveness of the protective coating system, it is important to follow the guidelines and recommendations provided by the ISO standards. These guidelines and recommendations are designed to ensure that the protective coating system is able to prevent corrosion for the expected service life of the structure, while also providing a high level of quality and performance.

Conclusion:

ISO 12944-4: 2018 and EN ISO 12944-1: 2017 are two important international standards that provide guidelines for selecting and implementing protective coatings on steel structures. These standards ensure that the protective coating system is designed to meet the specific requirements of the corrosive environment and that it is able to prevent.
