ISTA 3A states that for a standard, small, flat or elongated package type with less than or more than six faces, you are to develop a method for identifying each face, edge and corner then document that method with a diagram. One common method is to draw a virtual six-sided box around the test item. This virtual six-sided box should be large enough to allow for the entire test sample to fit within it. The next step would be identifying the faces of the virtual box by utilizing the establish method within ISTA 3A for six-sided packages. Those resulting face numbers are then transferred and assigned to the corresponding test sample contact areas. Figure 1 is an example of how to document this method for a hexagon package. This is also a common method utilized by carriers to determine dimensional weight of irregularly shaped packages (i.e. packages that are not six-sided). For assistance on hexagons or other irregularly shaped items, please don't hesitate to contact me directly at "How would you label the faces, corners and edges of an irregularly shaped package such as a hexagon carton within ISTA 3A?"
