b. Square or Rectangular Cans. These cans have three measurements. The
first measurement recorded is the longest measurement of the can end, the second
number is the shortest measurement of the can end, and the third number is the height
of the can. The height measurement is from the manufacturer's double seam (bottom of
the can) to the packer's double seam (top of the can). Thus, the can size is designated
by three sets of numbers and recorded in the following order: 402 (4 and 2/16 inches,
the longest can end measurement) by 303 (3 and 3/16 inches, the width of the can end)
by 1012 (10 and 12/16 inches, the can height). (See Figure 1-7.)
