This test method is intended to apply to the testing of all types of plastics, including cast, hot-molded, and cold-molded resinous products, and both homogeneous and laminated plastics in rod and tube form and in sheets 0. For example, Table 1 shows the time to approximate time saturation for various thickness of nylon Even for otherwise homogeneous materials, it may be slightly greater through cut edges than through molded surfaces.
