(a) Mature means that the apples have reached the stage of development which will insure the proper completion of the ripening process. Before a mature apple becomes overripe it will show varying degrees of firmness, depending upon the stage of the ripening process. The following terms are used for describing different stages of firmness of apples:

1. (1) Hard means apples with a tenacious flesh and starchy flavor.
2. (2) Firm means apples with a tenacious flesh but which are becoming crisp with a slight starchy flavor, except the Delicious variety.
3. (3) Firm ripe means apples with crisp flesh except that the flesh of the Gano, Ben Davis, and Rome Beauty varieties may be slightly mealy.
4. (4) Ripe means apples with mealy flesh and soon to become soft for the variety.

(f) Injury means any specific defect defined in this section; or an equally objectionable variation of any one of these defects, any other defect, or any combination of defects, which more than slightly detracts from the appearance, or the edible or shipping quality of the apple. The following specific defects shall be considered as injury:

1. (1) Russeting in the stem cavity or calyx basin which cannot be seen when the apple is placed stem end or calyx end down on a flat surface shall not be considered in determining whether or not an apple is injured by russeting. Smooth net-like russeting outside of the stem cavity or calyx basin shall be considered as injury when an aggregate area of more than 10 per cent of the surface is covered, and the color of the russeting shows no very pronounced contrast with the background color of the apple, or lesser amounts of more conspicuous net-like russeting when the appearance is affected to a greater extent than the above amount permitted.
2. (2) Sunburn or sprayburn, when the discolored area does not blend into the normal color of the fruit.
3. (3) Dark brown or black limb rubs which affect a total area of more than one-fourth inch in diameter, except that light brown limb rubs of a russet character shall be considered under the definition of injury by russeting.¹

4. (4) Hail marks, drought spots, other similar depressions or scars:

   1. (i) when the skin is broken, whether healed or unhealed;
   2. (ii) when there is appreciable discoloration of the surface;
   3. (iii) when any surface indentation exceeds one-sixteenth inch in depth;
   4. (iv) when any surface indentation exceeds one-eighth inch in diameter; or,
   5. (v) when the aggregate affected area of such spots exceeds one-half inch in diameter.¹

5. (5) Disease.

   1. (i) Cedar rust infection which affects a total area of more than three-sixteenths inch in diameter.¹

   3. (iii) Red skin spots which are thinly scattered over more than one-tenth of the surface, or dark, heavily concentrated spots which affect an area of more than one-fourth inch in diameter.¹

6. (6) Insects.

   1. (i) Any healed sting or healed stings which affect a total area of more than one-eighth inch in diameter including any encircling discolored rings.¹
   2. (ii) Worm holes.

(g) Damage means any specific defect defined in this section; or an equally objectionable variation of any one of these defects, any other defect, or any combination of defects, which materially detracts from the appearance, or the edible or shipping quality of the apple. The following specific defects shall be considered as damage:

1. (1) Russeting in the stem cavity or calyx basin which cannot be seen when the apple is placed stem end or calyx end down on a flat surface shall not be considered in determining whether or not an apple is damaged by russeting, except that excessively rough or bark-like russeting in the stem cavity or calyx basin shall be considered as damage when the appearance of the apple is materially affected. The following types and amounts of russeting outside of the stem cavity or calyx basin shall be considered as damage:

   1. (i) Russeting which is excessively rough or Roxbury Russet and other similar varieties.
   2. (ii) Smooth net-like russeting, when an aggregate area of more than 15 per cent of the surface is covered, and the color of the russeting shows no very pronounced contrast with the background color of the apple, or lesser amounts of more conspicuous net-like russeting when the appearance is affected to a greater extent than the above amount permitted.
   3. (iii) Smooth solid russeting, when an aggregate area of more than five per cent of the surface is covered, and the pattern and color of the russeting shows no very pronounced contrast with the background color of the apple, or lesser amounts of more conspicuous solid russeting when the appearance is affected to a greater extent than the above amount permitted.
   4. (iv) Slightly rough russeting which covers an aggregate area of more than one-half inch in diameter.¹
   5. (v) Rough russeting which covers an aggregate area of more than one-fourth inch in diameter.¹
2. (2) Sunburn or sprayburn which has caused blistering or cracking of the skin, or when the discolored area does not blend into the normal color of the fruit unless the injury can be classed as russeting.
3. (3) Limb rubs which affect a total area of more than one-half inch in diameter, except that light brown limb rubs of a russet character shall be considered under the definition of damage by russeting.¹

4. (4) Hail marks, drought spots, other similar depressions or scars:

   1. (i) when any unhealed mark is present;
   2. (ii) when any surface indentation exceeds one-eighth inch in depth;
   3. (iii) when the skin has not been broken and the aggregate affected area one-half inch in diameter;¹ or,
   4. (iv) when the skin has been broken and well healed, and the aggregate affected area exceeds one-fourth inch in diameter.¹
5. (5) Stem or calyx cracks which are not well healed, or well healed stem or calyx cracks which exceed an aggregate length of one-fourth inch.
6. (6) Invisible water core existing around the core and extending to water core in the vascular bundles; or surrounding the vascular bundles when the affected areas surrounding three or more vascular bundles meet or coalesce; or existing in more than slight degree outside the circular area formed by the vascular bundles.

2. (2) Sunburn or sprayburn which seriously detracts from the appearance of the fruit.
3. (3) Limb rubs which affect more than one tenth of the surface in the aggregate.
4. (4) Hail marks, drought spots, or scars, if they materially deform or disfigure the fruit, or if such defects affect more than one tenth of the surface in the aggregate: provided, that, no hail marks which are unhealed shall be permitted and not more than an aggregate area of one-half inch shall be allowed for well-healed hail marks where the skin has been broken.¹
5. (5) Stem or calyx cracks which are not well healed, or well healed stem or calyx cracks which exceed an aggregate length of one-half inch.

(j) Diameter.

When measuring for minimum size, diameter means the greatest dimension of the apple measured at right angles to a line from stem to blossom end. When measuring for maximum size, diameter means the smallest dimension of the apple determined by passing the apple through a round opening in any position.
