In case of light damage to the thermal deformation of materials and abnormal phenomenon is the experiment failed. B: the impact of high temperature and pressure start test. Major test equipment: incubators, thermometers, voltage regulator, voltmeter and clock. Main test items: high-temperature startup performance and reliability testing quantity: 10. Test Method: Plug trials. At high temperatures, the regulator voltage to 250V, switch three times, at intervals of not less than 8 seconds (an interval of 8 seconds is to be the capacitance of all the discharge lamps to reduce the mutual interference), in the process , lamps should not be damaged, or they will be disqualified. C: low temperature. Main Test Equipment:
Cold boxes, thermometers,[link widoczny dla zalogowanych], voltage regulator, voltmeter and clock. Main test items: low temperature and pressure to start. The number of tests: 10. Test Method: tested lamps into the cold chamber, the connection circuit,[link widoczny dla zalogowanych], the voltage regulator's output voltage to 180V (voltage regulator power supply only to the lamp under test),[link widoczny dla zalogowanych], open the cold box power supply, the temperature set at -15 ��, to be inside the box again when the temperature dropped to -15 �� for 2 hours so the lamps to cool, turn on the lamp power supply, observe the results.
In case of light damage, and abnormal phenomena can not be started while the experiment failed. (Bell brand of constant temperature and humidity box BE-TH Series) D: low-temperature high-pressure shock launch test. Main Test Equipment: Cold boxes,[link widoczny dla zalogowanych], thermometers, voltage regulator, voltmeter and clock. Main test items: the number of low-temperature high-pressure shock reliability tests: 10.
Test Method: Plug trials. In the low-temperature conditions, the regulator voltage to 250V, switch three times, at intervals of not less than 8 seconds (an interval of 8 seconds is to be the capacitance of all the discharge lamps to reduce the mutual interference), in the process , lamps should not be damaged, or they will be disqualified. E: vibration test. Main testing equipment: vibration test stand a number of tests: 10 packaging.
