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.
