6. Action time
6.1 For overvoltage relay
      When the action value is 1.1 times, the action time is no more than 0.12s.At 2 times of the action value, the action time is no more than 0.04s.
6.2 For low voltage relays
      When the working voltage of the relay is 0.5 times the setting voltage, the operation time shall not be greater than 0.51s.
7. Overvoltage capability: When the coils are connected in parallel, the voltage is uniformly raised from zero to 1.05-2.2 times of the setting voltage at the minimum setting value. Within this range, the relay should not vibrate to make the moving contact stop working.After this test, the relay shall still be able to meet the requirements of the technical conditions.
8. Overvoltage: when the setting value of the relay is added 1.75 times or higher, the moving contact of the relay shall close without jitter. 
9. When there are no external collisions and vibrations.When the working voltage at each setting position (except the first point) of the over-voltage relay is 0.6 times the setting value, its dynamic breaking contact should close the circuit reliably.
10. When the operating voltage of the low-voltage relay is 0.6 times the setting voltage or lower, its dynamic breaking contact shall be closed without jitter.
11. When there is no external collision or vibration, when the working voltage at each setting position of the low-voltage relay is not less than 1.5 times the setting voltage, its moving contact should be able to close the circuit by ground.
12. At operating and return voltages: the moving system of the relay should not be stuck in the middle.
13. When the relative humidity is not more than 85% of the surrounding air, the relay circuit to shell (shell of conductive metal part) of the insulation resistance, using the 500 v megohmmeter, measure shall be not less than 300 m Ω.
14. The insulation of the conductive part of the relay to the housing (non-conductive metal part of the housing) can withstand a test lasting 1min at 50Hz ac voltage of 2kV.
15. Contact disconnection capacity: When the voltage is no more than 250V and the current is no more than 2A, the disconnection power of the contact is 50W in the DC circuit with inductive load (time constant is no more than 5x10s) and 250VA in the AC circuit.
16. Power consumption: At the minimum setting value, the power consumed by the relay coils shall not exceed 20VA.
17. When the temperature of the surrounding medium is +40℃, when the relay operates under the long-term allowable current and voltage as shown in Table 2 and Table 3, there will be no damage to insulation and other electrical components, and the temperature rise of the coil will not be greater than 65℃.
18. Life: the electrical life of the relay is 500 times, and the mechanical life is 5000 times.
