3)For size. 5 percent, by count, for almonds which are smaller than the specified minimum thickness;
4) For loose extraneous and foreign material. 2 percent, by weight, including therein not more than 1 percent which can pass through a round opening 24/64 inch (9.5 mm) in diameter: Provided, that such material is practically free from insect infestation; and,
5) For internal (kernel) defects. 10 percent, by weight, for almonds with kernels failing to meet the requirements of this grade: Provided, that not more than one-half of this tolerance or 5 percent shall be allowed for kernels affected by decay or rancidity, damaged by insects or mold or seriously damaged by shriveling: And provided further, that no part of this tolerance shall be allowed for live insects inside the shell.
