The outer conductor integrity test is designed to evaluate the ability of an outer conductor material to withstand heat exposure and subsequent soldering.
Samples are placed into an oven at the specified temperature for no less than 1 hour and 30 minutes. After the heat exposure, samples are maintained at room temperature for no less than 4 hours. One end of each sample will then be immersed in molten solder to a specified depth for a specified duration and, once again, conditioned back to room temperature. The samples are visually inspected for any damage to the outer conductor.
