4. Reliability Test
Afterbeing worked inachamberat +85 for 1hour, then
soundershall be placed inachamberat -40 for 1hour(1cycle
is the belowdiagram).
After6abovecycles, soundershall be measured afterbeing
placed innaturalcondition for1hour.
Afterbeing placed inachamberwith 90 to95%R.H.at +40±2
for2hand then being placed innaturalcondition for2h,
soundershall be measured.
First being worked inachamberwith -40±2for 2hand
then being placed inachamberwith -40±2 ℃for16h, finally
being placed innaturalcondtion for2h, soundershall be
measured.
Afterbeing woked inachamberwith +85±2for 2h and then
being placed innaturalcondition for2h, soundershall be
