    After being worked in a chamber at  +85

 for 

1 hour, then 

sounder shall be placed in a chamber at  -40 

 for 

1 hour(1 cycle 

is the below diagram).

     After 6 above cycles, sounder shall be measured after being 

placed in natural condition for  1 hour.

   After being placed in a chamber with  90 to 95%R.H. at +40

±

 for 2 h and then being placed in natural condition for  2h , 

sounder shall be measured. 

    First  being worked  in a chamber with  -40

±

 for 

2h and 

then being placed in a chamber with  -40

±

 for 16h, finally 

being placed in natural condtion for 2h, sounder shall be  
measured.

   After being woked in a chamber with  +85

±

 for 

2h and then 

being placed in natural condition for  2h, sounder shall be 
measured.

         After test(1~7item), the transducr S.P.L . difference shall be within 

±

10dB, and the 

appearance not exist any change to be harmful to normal operation(e.g.cracks,rusts,damages 
and especially distortion).
