3-4 Noise:Pump body underlay is 5 cm thick sponge, placed on the noise meter 30 cm, Rated voltage under inflation pressure from 0 to 300mmHg the measured value is less than 60dB

3-5 Flow ：≥2.0LPM

3-6 Maximum pressure：In Rated voltage voltage causes inflation pressure from 0 to stop the booster of the highest pressure value is（Positive pressure ≥750mmHg  Negative pressure ≥420mmHg）

3-7 Operation temperature range: The temperature have to be between 5℃ and 50℃ and humidity must  is  between 30％and 80％RH to function the pump well.

3-8 Preservation temperature range:The temperature has to be between negative 20℃and positive 60℃ and humidity has to be between 30％and 85％ RH to keep the pump in a good condition.

4.Reliability test:

4-1 Low-temperature characteristic:Putting the pump in the temperature at negative 20℃ for 72 hours;then taking it  out and putting it in a room temperature at 20℃±5℃ for two hours.Under this circumstance,running through test 3-3 3-4 3-5 3-6  and finding  out that the pump still performs well.

4-2 High-temperature characteristic:Putting the pump in the temperature at 60℃ for 72 hours;then taking it out and  putting it in a room temperature at 20℃±5℃ for two hours。Under this circumstance，running through test 3-3 3-4 3-5 3-6 and finding  out that the pump still performs well.

4-3 High-temperature & High humidity:Putting the pump in the temperature at 60℃ and the 20℃±5℃ for two hours. Under this circumstance，running through test 3-3 3-4 3-5 3-6  and finding out that the pump still performs well.

4-4 Low－ temperature environment test:Measuring after 5 hours neglect and there are no abnormalities a deed following  test in 5℃.

4-5 High－ temperature environment test:Measuring after 5 hours neglect and there are no abnormalities a deed following test  in 50℃.

4-6 Life test：In 100ml tank,pumping 10 seconds ，on 5 seconds for a  cycle,test for 30,000 cycles ,and the tested by  point 3-3 3-4 3-5 3-6,the under performance range is within 15%

5.Others

5-1 Fall test:Fall test: Basic performance and the structure shall not be defected after following test: With a standard packaging conditions, the dropping it at the front, side, and edges part from 50cm height to the concrete floor.

5-2 Unusual test:There is no burning and smoking omlurrence while the power is on with Rated voltage for 8 hours continuously.

5-3 Motor Terminal:No abnormality omlurs when a 0.5Kg static is hanging in the parallel direction of the Terminals .The terminals must be 380 ℃ temperature soldering iron, the requirements to complete the operation in 2 seconds.

5-4 Appearance:The appearances of the valve shall not contain cracks and impurities
