The required standards for environmental tests for communication and electronic equipment used currently are not standards into which the Korean climate and use environment are taken into consideration. But the most used environmental testing standards of the U.S. army(MIL-STD-810) has been used without taking into consideration the Korean domestic situation and conditions by simply translating the US standards. Adherence to these standards may increase in the manufacturing costs according to excessively strict standards. Therefore, this paper will propose a new environmental test standards for temperature.
