a For thickness gaging (lower maximum for flaw inspection)

b Duration of ferrous corrosion inhibition (mild steel & cast iron): 100 = long term protection, 80 = 60 days-steel, 14 days - iron, 60 = 30 days - steel, 7 days - iron, 40 = 7 days - steel, 2 to 8 hours - iron, 20 = 8 hours-steel, 0 to 2 hours - iron, 0 = no inhibition, like plain water.

c 10 = thick paste, 5 = slow flowing gel, 0 = water

d For thickness gaging (lower maximum for flaw inspection)

e Typical values only, request current C of A for actual values

f 100 = easiest to remove with appropriate solvent, 0 = difficult to remove even with solvent and scrubbing

N/A = Not Available, Information in green indicates best estimates.
