(149 [deg]F.) for an electrolytic type and 90 [deg]C. (194 [deg]F.) for other than an electrolytic type. \2\ The temperature indicated refers to the hottest spot on the outside surface of the coil measured by the thermocouple method. \3\ The limitations on rubber- and thermoplastic-insulated wires and cords and on phenolic composition do not apply if the insulation or the phenolic has been investigated and found to have special heat-resistant properties, or if the insulation meets the thermal requirements. \4\ 40 less than melting point. \5\ 104 less than melting point.
