#### § 51.713 Classification of defects.

All references to area or aggregate area, or length in this standard are based on an orange 27⁄8 inches in diameter, allowing proportionately greater areas on larger fruit and lesser areas on smaller fruit.

| Green spots or oil spots | More than slightly affecting appearance | Aggregating more than a circle 7/8 inch in diameter | Aggregating more than a circle 11/4 inches in diameter. | |
| Hail | Not well healed, or aggregating more than a circle 1/4 inch in diameter | Not well healed, or aggregating more than a circle 3/8 inch in diameter | Not well healed, or aggregating more than a circle 1/2 inch in diameter | Not well healed, or aggregating more than a circle 3/4 inch in diameter. |
| Scab | | Materially detracts from the shape or texture, or aggregating more than a circle 5/8 inch in diameter | Seriously detracts from the shape or texture, or aggregating more than a circle 3/4 inch in diameter | Aggregating more than 25 percent of the surface. |
| Scale | More than a few adjacent to the “button” at the stem end, or more than 6 scattered on other portions of the fruit | Aggregating more than a circle 5/8 inch in diameter | Aggregating more than a circle 3/4 inch in diameter | Aggregating more than 25 percent of the surface. |
| Scars | Depressed, not smooth, or detracts from appearance more than the amount of discoloration permitted in the grade | Deep, rough or hard aggregating more than a circle 1/4 inch in diameter; slightly rough with slight depth aggregating more than a circle 7/8 inch in diameter; smooth or fairly smooth with slight depth aggregating more than a circle 11/4 inches in diameter | Deep, rough aggregating more than a circle 1/2 inch in diameter; slightly rough with slight depth aggregating more than a circle 11/4 inches in diameter | Deep, rough or unsightly that appearance is very seriously affected. |
| Skin breakdown | | Aggregating more than a circle 1/4 inch in diameter | Aggregating more than a circle 5/8 inch in diameter | Aggregating more than 25 percent of the surface. |
| Sunburn | | Skin is flattened, dry, darkened or hard, aggregating more than 25 percent of the surface | Affecting more than one-third of the surface, hard, decidedly one-sided, or light brown and aggregating more than a circle 11/4 inches in diameter | Aggregating more than 50 percent of the surface. |
| Sprayburn | | | Hard, or aggregating more than a circle 11/4 inches in diameter | Aggregating more than 25 percent of the surface. |
| Split, rough or protruding navels | Split is unhealed; navel protrudes beyond general contour; opening is so wide, growth so folded and ridged that it detracts noticeably from appearance | Split is unhealed, or more than 1/4 inch in length, or more than 3 well healed splits, or navel protrudes beyond the general contour, and opening is so wide, folded or ridged that it detracts materially from appearance | Split is unhealed, or more than 1/2 inch in length, or aggregate length of all splits exceed 1 inch, or navel protrudes beyond general contour, and opening is so wide, folded and ridged that it seriously detracts from appearance | Split is unhealed or fruit is seriously weakened. |
