The size designations and measurement requirements for the respective sizes are:
Select size raisins means that no more than 60 percent, by weight, of all the raisins will pass through round perforations 22/64-inch in diameter, but not more than 10 percent, by weight, of all the raisins may pass through round perforations 20/64-inch in diameter.
Small size raisins means that 95 percent, by weight, of all the raisins will pass through round perforations 24/64-inch in diameter, and not less than 70 percent, by weight, of all raisins will pass through round perforations 22/64-inch in diameter.
Mixed size raisins means a mixture that does not meet either the requirements for “select” size or for “small” size.
