What is this standard about?
There are a few different ways of protecting steel structures from corrosion which can potentially cause very costly damage. This standard is one in a series of eight that deals with protecting steel using paint systems and covers. It provides concise, clear, up-to-date and comprehensive instructions to ensure effective corrosion protection.
The other standards in the ISO 12944 series are:
- Part 1: General introduction
- Part 2: Classification of environments
- Part 3: Design considerations
- Part 4: Types of surface and surface preparation
- Part 6: Laboratory performance test methods and associated assessment criteria
- Part 7: Execution and supervision of paint work
- Part 8 Development of specifications for new work and maintenance
Who is this standard for?
- Structural fabricators and engineers
- Thermal sprayers
- Galvanizers
- Coating and paint manufacturers
- Companies carrying out corrosion protection work
- Companies owning steel structures, e.g. offshore steel structures
- Planners
- Consultants
- Inspectors of protective coatings
Why should you use this standard?
It describes the types of paint and paint system commonly used for corrosion protection of steel structures. It also gives guidelines on the selection of paint systems available for different environments (see ISO 12944-2) except for corrosivity category CX and category Im4 as defined in ISO 12944-2, different surface preparation grades (see ISO 12944-4), and the durability grade to be expected (see ISO 12944-1).
What’s changed since the last update?
This version is more user-friendly with updated normative references, clarified essential requirements and some restructuring to make it easier to use. As well, the following have been added:
- A new normative annex for “Minimum requirements for protective systems”
- New types of coatings (polyaspartic, fluoropolymer, fluoroethylene/vinyl ether co-polymer and polysiloxanes)
- Descriptions for intermediate coats and topcoats
- New informative annexes on “Paint systems on hot dip galvanized steel” and “Paint systems on thermal-sprayed metallic coatings”
