Corrosion coupons
Corrosion coupons are used to classify (industrial and marine atmospheres) to monitor atmospheric corrosivity in accordance with ISO 22426 and ISO 12944. The following products are available:
-
CLIMAT units (wire-on-bolt test) per ASTM G116
-
'ISO" units (flat mild steel and hot-dip galvanised steel, aluminium and copper) per ISO 9226:2012
-
Open helix wire devices ( ISO 9226:2012 steel, aluminium, zinc and copper)
Coupons are marked for proper identification. Laboratory test reports (after exposure) identify contaminants, atmospheric corrosion rates and corrosivity categories

Natural Weathering Programme
Corrosion coupons are exposed at our C3 - CX exposure sites across South Africa.
