Abstract : A very simple cold-bend test was devised and tested for evaluating thermoplastic jackets used on mine-power-feeder cables. A test sample is bent into a semicircle whose radius is equal to the minimum bend radius recommended by IPCEA and then cooled to the desired test temperature (-35 deg C). While at temperature, the sample is straightened by pulling the cable ends with a winch arrangement. The results show that of the jackets tested, those which cannot withstand the test literally burst when the sample is straightened. (MM)
