Issue Date: 8/1/2012
Effective Date: 8/1/2012
When classes are determined by the density of articles, as tendered for shipment, the word “density” means pounds per cubic foot (pcf).
- The cubage of loose articles or pieces, or packaged articles of a rectangular, elliptical or square shape one plane shall be determined by multiplying the greatest straight line dimensions of length, width and depth in inches, including all projections, and dividing the total by 1,728 cubic inches (one cubic foot). The density shall be the result of the division of the weight or the articles, piece or package by the ascertained cubic feet.
- To determine the density of a cylindrical shaped article or any article other
than a square, elliptical or rectangular-shaped article in a single plane, square the greatest dimension on the cylindrical or other than square, elliptical or rectangular plane (multiply the dimension by itself) and multiply that result by the height or length. If result is in cubic inches, divide by 1,728 cubic inches (one cubic foot). The density shall be the result of the division of the weight of the article by the ascertained cubic feet.
