Position	Horizontal
Load	Air pressure 300mmHg
Operating condition	5℃~45℃, RH 30%~85%
Storage condition	-20℃~60℃, RH 30%~85%

Rated voltage	3.70VDC
Operating voltage	3.0 - 4.5 VDC
Rated current	＜650 mA；The highest current is less than 650mA while pressurizing with DC3.7V from 0 to 300mmHg
Inflation time	At DC3.7V to pressurize in a 100cc tank from 0 to 200 mmHg, Inflation time 6 seconds.
Air flow	At DC3.7V ,the air flow is more than 2.0L/min with no load..
Max pressure	The maximum pressure value shall be more than 400mmHg while pressurizing with DC 3.7 V tank from 0 till dead-head pressure value
Max vacuum	The maximum vacuum value shall be Less than-450mmHg while pressurizing with DC 3.7V tank from 0 till dead-head vocuum value.
Noise	Putting a 5 cm sponge under the pump,and placing it about 30 cm away from the noise meter,The evaluated noise level shall be less then 60dB while pressurizing with DC 3.7V from 0 to 200mmHg.

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 2 hours,Under this circumstance,running through performance test and finding out that the pump still performs well.
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 2 hours,Under this circumstance,running through perforamance and finding out that the pump still performs well.
High-temperature & High humidity	Putting the pump in the temperature at 60℃ and the humidity at 95% for 72 hours;then taking it out and putting it in a room temperature at 20 ± 5 ℃ for 2 hours.Under this circumstance,running through performance test and finding out that the pump still performs well.
Temperature & humidity cycle test	After doing the temperature and humidity cycle test,-20℃* 2Hr → +25℃* 1Hr→ +60℃ 85%RH* 2Hr →+25℃*1Hr,for twelve times,the pump shall still perform the same functions proved by running through performance test.
Life test	In a 500CC tank,pressurizing for 10 seconds , stopping for 2 seconds,exhaust for 5 seconds is as one cycle,Doing it for 30,000 times, then examine the pump by testing performance and figure out than the pump is still in a good function.

The lead tension	Hanging a 0.5 Kg static load on the terminal of the pump will not cause a damage on the pump
Solder requirements	Motor terminal for Soldering process the heat temp. is controlled by 330℃,and operating time is for 3 sec only.
Appearance	The appearances of the pump shall not contain cracks and impurities.
Fall test	Basic performance and the structure shall not be defected after following test; With a standard packaging conditions,then dropping it at the front,side,and edges part from the height of 50 cm to the concrete floor.
Unusual test	There is no burning and smoking occurrence while the power is on with DC4.5V for 8 hours continuously.
