Test Item Drop Test
Test Condition Criteria The sample shall not Drop the test piece one time from the height of 1m in each of X, Y and Z directions onto the lauan have any abnormality in the appearance and the material of 30 mm thickness.
humidity detection output shall be in the electric characteristics of item 7.

Heat Shock Exposure to High Temperature Exposure to High Humidity Exposure to Low Temperature Load Life
The samples are subjected to 10 cycles of 2 hours’ exposure of each of –25deg.C and +70deg.C (Do not let it have dewdrops.) The samples are exposed to a temp. of +70deg.C for 1000 hrs. The samples are exposed to a temp. of +40deg.C with 95%RH for 1000 hrs. The samples are exposed to a temp. of –25deg.C for 1000 hrs. The samples are subjected to a consecutive electric load in the normal temperature and humidity for 1000 hrs.
The variation of the humidity detection output shall be within +/- 5% against the initial value.
*1)The measurement of the humidity detection output is done after 15 minutes has passed with the advantage way-type precision humidity producing device after the temperature humidity setting. *2)The measurement of the reliability test parts is done after they are left for more than two hours in the normal temperature and the normal humidity.
9. Notes for Use
(1)Do not get the product wet in the water, and do not let it have dewdrops. Characteristics may change permanently. (2)Do not make foreign materials such as a solvent, oil and fat stick to the humidity sensor. It may stop fulfilling normal features. (3)Do not use for medical apparatus (application involving risk of affecting life).
