Rationale: /86 application: "Not for Navy Use". Having a seamless construction wire
>> /186 enables the improved configuration to be employed in thermocouple extension cables.
>> NOTE: the associated AS5419/7 will also be impacted accordingly to update it from /86 to /186.
>> The rationale has to do with the /86 being a tape-wrapped construction. As such it has forced hydrolysis test issues with inferior performance when compared to the seamless /186. Fluid susceptibility is of concern in Naval applications. That was the reason for the creation of /186, to address the issues. The /186 is simply an improved wire construction.
