9. Internal corrosion. If the container is a metal can, two filled and sealed cans of water must be immersed in boiling water for 6 to 8 hours. At the end of the boiling period they must be cooled to room temperature. The cans must then be placed upright in a freezing compartment at approximately -20 C (-4 F) for 16 hours. The cycle of alternating boiling and freezing must be continued until six cycles have been completed. After the freezing portion of the cycle, the frozen cans may be immersed directly in the boiling water for the next cycle, or held at room temperature until it is convenient to start the next cycle. At the completion of the six cycles, the water in the cans, and the water in two cans not subjected to the temperature cycling must be chemically analyzed. The water in the cycled cans must not show an increase in products of corrosion as compared to the uncycled cans.
