5-1. VIBRATION TEST
At condition,amplitude and oscillation shall be 2mm and 1,000 C.P.M.
respectively. There shall be no looseness after each2 hours of
top-bottom back-forth and right-left vibrations.
5-2. DROP TEST
After the packed tuner at 50 cm height is dropped 6 tims from
each side,gain variation shall be less then 2dB and frequency drift
shall be less than 200 kHz
5-3. TEMPERATURE TEST
After the tuner shall be exposed for each 120 minutes in a test
Chamber of temperature cycle at 20℃,50℃,0℃,20℃and then the
tuner shall be operated satisfactorily electrical
performance.
5-4. HUMIDITY TEST
After 5 hours exposure in a test chamber at 50℃±5℃ or 0℃±5℃and
90±5%R.H.,then exposed for 4h in a room temperature,
there shall be no deterioration in electrical performance.
5-5. TEMPERATURE SHOCK TEST
After 12 hours exposure in a test chamber at 60℃±2℃ or -10℃±2℃
and them exposed in a room temperature for more than 4h,the tuner
shall be operate satisfactorily.
