8. reliability tests no. test item test condition criteria 1 drop test d rop the test piece one time from the height of 1m in each of x, y and z directions onto the lauan material of 30 mm thickness. the sample shall not have any abnormality in the appearance and the humidity detection output shall be in the electric characteristics of item 7. 2 heat shock 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.) 3 exposure to high temperature the samples are exposed to a temp. of +70deg.c for 1000 hrs. 4 exposure to high humidity the samples are exposed to a temp. of +40deg.c with 95%rh for 1000 hrs. 5 exposure to low temperature the samples are exposed to a temp. of ?25deg.c for 1000 hrs. 6 load life 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 ou tput is done after 15 minutes has passed with the advantage way-type precision humi dity 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). hokuriku electric industry co.,ltd.
