This document specifies an external protective coating system which is factory applied to ductile iron pipeline components as specified in ISO2531 , ISO7186 and ISO16631 . This coating system comprises an electro-deposited metallic zinc-based coating of
pure metallic zinc with a purity of 99,99%,
zinc and aluminium alloy with or without other metals, or
other zinc alloys
followed by a finishing layer that can be bituminous paint or synthetic resin compatible with zinc-based coating.
NOTE ISO8179‑2 deals with zinc-rich paint coating.
