What is BS EN ISO 12944-9:2014?

BS EN ISO 12944-9:2014 is an international standard that provides guidelines for the corrosion protection of steel structures subjected to environments such as atmospheric exposure, immersion in water, or buried in soil. It is part of the ISO 12944 series, which covers different aspects of corrosion protection for steel structures.

Scope and Purpose

The scope of BS EN ISO 12944-9:2014 is to establish principles for the selection and application of corrosion protection systems for steel structures exposed to various environmental conditions. It aims to ensure the durability and longevity of steel structures by providing guidance on the design, materials, surface preparation, application methods, quality control, and maintenance of corrosion protection systems.

Key Requirements

This standard outlines key requirements for different levels of corrosivity categories and surface profiles. It defines the performance criteria for corrosion protection systems, including their ability to withstand specific environments and provide an extended service life for steel structures.

Some of the key requirements covered in BS EN ISO 12944-9:2014 include:

Atmospheric corrosion categories and corresponding protective systems

Definitions and characteristics of corrosivity categories

Surface preparation methods and cleanliness standards

Application methods and recommended coating systems

Quality control procedures and inspection methods

Maintenance recommendations for prolonging the service life of corrosion protection systems
