ISO 12944

ISO 12944 specifies guidelines for the corrosion protection of steel structures using coating systems to extend the life of steel structures and reduce maintenance costs.
It covers the selection, design, application and maintenance of coating systems for different environments (corrosivity categories C1-CX) and duration of protection (low, medium, high).
Sherardizing is specifically mentioned in Parts 1, 4, 5 and 8.
