1. SPECIAL ENVIRONMENT TEST 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 each 2 hours of top-bottom back-forth and right-left vibrations.After this test the gain variation shall be less than 3dB and frequency drift shall be less than 200 kHz. 5-2. DROP TEST After the packed tuner at 50Cm height is dropped six times from each side, gain variation shall be less then 3dB 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 2℃,40℃,0℃,20℃ and then the tuner shall be operated satisfactorily electrical performance. 5-4. HUMIDITY TES After 5 hours exposure in a test chamber at 40℃±5℃ and 90 ± 5% R.H.,then exposed for 4 hours in a room temperature, there shall be no deterioration in electrical performance. In addition, the gain variation shall be less than 3dB and frequency drift shall be less than 500 kHz. 5-5. TEMPERATURE SHOCK TEST After 12 hours exposure in a test chamber at 60℃±2℃ or -20℃±2℃ and them exposed in a room temperature for more than 4 hour, the tuner hall be operate satisfactorily. 2.
