What is ISO 12944‑5 - Protective paint systems about?
ISO 12944‑5 is part 5 of a multi-series of international standards on paints and varnishes which covers corrosion protection of steel structures by protective paint systems.
ISO 12944‑5 describes the types of paint and paint system commonly used for corrosion protection of steel structures.
ISO 12944‑5 also gives guidelines for the selection of paint systems available for different environments except for corrosivity category CX and category Im4.
Who is ISO 12944‑5 - Protective paint systems for?
ISO 12944‑5 on protective paint systems is relevant to: 
- Paints and varnishes manufacturers
- Steel industry
Why should you use ISO 12944‑5 - Protective paint systems?
Unprotected steel in the atmosphere, in water and in soil is subjected to corrosion that may lead to damage. Therefore, to avoid corrosion damage, steel structures are normally protected to withstand the corrosion stresses during the required service life required of the structure.
There are different ways of protecting steel structures from corrosion. ISO 12944 (all parts) deals with protection by paint systems and covers, in the various parts, all features that are important in achieving adequate corrosion protection.
ISO 12944‑5 gives some terms and definitions related to paint systems in combination with guidance for the selection of different types of protective paint systems. This guidance can help you make better business decisions and in turn increase revenue.
With the guidance of ISO 12944‑5, you can protect your machinery made of steel, this can help you in reducing potential costs and safety risks.
