ARSD 44:02:07:43. General equipment and utensils -- Materials and design

Materials that are used in the construction of utensils and food-contact surfaces of equipment may not allow the migration of deleterious substances or impart colors, odors, or tastes to food. Under normal use conditions materials must be safe; durable; corrosion-resistant; nonabsorbent; sufficient in weight and thickness to withstand repeated warewashing; finished to have a smooth, easily cleanable surface; and resistant to pitting, chipping, crazing, scratching, scoring, distortion, and decomposition.
