ISO 12944 Paints and varnishes – Corrosion protection of steel structures by protective paint systems

The reference for specifying paint systems: corrosivity categories C1–C5 and CX, durability ranges, design for corrosion protection, surface preparation, paint systems, testing and inspection.

CodeISO 12944Issued byISOFieldCorrosion protection

What it covers

Environment classification and durability (L, M, H, VH).
Typical paint systems for each category, laboratory performance tests, execution and supervision.

Key points for fabricators

Durability is the expected time to first major maintenance, not a guarantee.
Dry film thickness readings are a standard release record.

How PEB Studio supports it

The project record stores the surface protection specification, and the QC library includes DFT inspection before release for shipment.

This page is a summary for orientation. Always work from the edition of the standard named in the project specification.
