This Standard provides guidance on practical procedures, for use in the field, to assess the degree of cure or through-dry in coatings. Applicable coatings include those that dry by oxidation (e.g., alkyd), solvent evaporation (e.g., lacquers such as chlorinated rubber), those that set by chemical reaction with a liquid curing agent (e.g., epoxy) and those that react with the atmosphere (e.g., inorganic zinc).
