EN ISO 12944-4 Paints and Varnishes - Protection of Steel Structures with Corrosion Protective Paint Systems - Part 4: Surface Types and Surface Preparation Test

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN ISO 12944-4 testing. This standard covers the following surface types and their preparation for steel structures made of carbon or low alloy steel:

• Uncoated surfaces;
• Surfaces thermally sprayed with zinc, aluminum or their alloys;
• Hot-dip galvanized surfaces;
• Zinc coated surfaces;
• fragmented surfaces;
• Surfaces painted with prefabrication primer;
• Other painted surfaces.

This standard defines a range of grades of surface preparation, but does not specify any requirements for the condition of the substrate prior to surface preparation.

Highly polished surfaces and hardened surfaces are not covered by this document.

In the atmosphere, water and soil, unprotected steel is subject to corrosion that can cause damage. Therefore, to prevent corrosion damage, steel structures are normally protected to withstand the corrosion stresses that the structure will be subjected to during its required service life.

There are different ways to protect steel structures from corrosion. EN ISO 12944 (all parts) deals with protection with paint systems and covers all the features that are important in obtaining adequate corrosion protection on various parts. Additional or other measures are possible but require specific agreement between the parties involved.

To ensure effective protection of steel structures against corrosion, owners of such structures, planners, consultants, companies carrying out corrosion protection work, protective coating inspectors and coating material manufacturers need to have the latest information. succinctly on corrosion protection with paint systems. It is vital that such information is as complete, clear and easy to understand as possible in order to avoid difficulties and misunderstandings between parties involved in the practical implementation of conservation work.
