If the can size in question is not listed, calculate the value for column II as follows: From the list select as the comparable can size that one having nearest the water capacity of the can size in question, multiply the value listed in column II for the same form of tuna ingredient by the water capacity of the can size in question, and divided by the water capacity of the comparable can size. Water capacities are determined by the general method provided in §130.12(a) of this chapter. For the purposes of this section, cans of dimensions 211*109 shall be deemed to have a water capacity at 68 °F of 3.55 avoirdupois ounces of water; cans of dimensions 307*113, a water capacity of 7.05 avoirdupois ounces of water; cans of dimensions 401*206, a water capacity of 13.80 avoirdupois ounces of water; and cans of dimensions 603*408, a water capacity of 68.15 avoirdupois ounces of water.
For can size 211*109
Press cylinder:
Inside depth, approximately 33/4 inches.
Inside diameter, 2.593 inches.
Wall thickness, approximately 3/8 inch.
Plunger:
Thickness, approximately 1 inch.
Diameter, 2.568 inches.
For can size 307*113
Press cylinder:
Inside depth, approximately 4 inches.
Inside diameter, 3.344 inches.
Wall thickness, approximately 3/8 inch.
Plunger:
Thickness, approximately 11/4 inches.
Diameter, 3.319 inches.
For can size 401*206
Press cylinder:
Inside depth, approximately 41/8 inches.
Inside diameter, 3.969 inches.
Wall thickness, approximately 1/2 inch.
Plunger:
Thickness, approximately 11/4 inches.
Diameter, 3.944 inches.
For can sizes where the diameter is greater than 401, the core cutter described in paragraph (c)(3)(ii) of this section shall be used and the resulting core pressed in the press cylinder for can size 401*206. For can sizes differing from those specified in this paragraph (c)(3)(i), special press cylinders and plungers may be used. Special press less than the outside diameters, at the cylinders have inside diameters 1/10 -inch double seam, for the can sizes for which the cylinders are used; plunger diameters are 0.025-inch less than the inside diameters of the press cylinders.
