The present invention comprises a duplex thermal transfer pack. The pack includes a large bag containing many smaller sub bags. Each sub bag contains plain water. The volume within the large bag but outside the sub bags contains a second substance. This second substance freezes with a consistency akin to crushed ice or packed snow. The second substance allows the thermal transfer pack to remain malleable even when its contents are frozen.

A load test device includes: a resistor unit that includes a plurality of resistors that receive supplied power and a wall (holding frame) that holds opposite ends of each of the plurality of resistors; and an insulating cap that is attached to a portion of a terminal of the resistor that protrudes from the wall. The cap is composed of a material that is deformed by heat. When a temperature of the terminal becomes equal to or higher than a first temperature, the cap is deformed by heat and detached from the terminal.
