Scale	Aggregating more than a circle 3/8 inch (9.5 mm) in diameter	Aggregating more than a circle 5/8 inch (15.9 mm) in diameter	Aggregating more than 25 percent of the surface.

Skin breakdown	Aggregating more than a circle 1/2 inch (12.7 mm) in diameter	Aggregating more than a circle 3/4 inch (19.1 mm) in diameter	Aggregating more than 25 percent of the surface.	Sprayburn	Skin is hard and aggregating more than a circle 3/4 inch (19.1 mm) in diameter	Skin is hard and aggregating more than a circle 1 1/4 inches (31.8 mm) in diameter	Aggregating more than 25 percent of the surface.

Note: All references to area or aggregate area, or length are based on a tangerine 2 1/2 inches in diameter (63.5 mm), allowing proportionately greater areas on larger fruit and lesser areas on smaller fruit.
