Open the container and pour the nuts loosely into a vertical graduated cylinder (do not tilt) of appropriate size fitted with a funnel which has been modified, if necessary, to provide a minimum opening of 1 -inch diameter. (If the loose volume of the nuts is less than 500 milliliters, use a 500-milliliter cylinder with an inside diameter of approximately 1 inches; but if the loose volume is 500 milliliters or more, use a 1,000-milliliter cylinder with an inside diameter of approximately 2 inches.)
