A Instead of viscosity of the residue, the specifying agency, at its option, can specify penetration 100 g: 5 s at 25°C [77°F] of 120 to 250 for Grades MC-30, MC-70, MC-250, MC-800, and MC-3000. However, in no case will both be required. † Editorially corrected to match originally published D2027–97.
