2001《Respiratory protective devices-Methods of test-part3：Determination of
breathing resistance》In in addition to mouth mask respiration indices resistance, it is also mentioned that being tested using respiration simulator method
Mouth mask dynamic respiratory resistance.Journey is exhaled-is drawn through in dynamic move in circles when people wears mouth mask, respiratory air flow speed is in sine wave
The resistance change during real-time recording respiration under different respiratory flows is answered in shape, the test of dynamic respiratory resistance, and true reappearance is worn
Scene.In addition in order to improve wearing comfort, mouth mask Chang Huijia matches somebody with somebody outlet valve, includes outlet valve silica gel pad, and it is in air-breathing
Close, open during expiration, during static test, expiration valve gasket is in normally opened/normally off, rather than during actual wear
The opening/closing state of alternating, therefore the performance of expiration valve gasket during use can not be judged.
Mouth mask standard in China's still introduces dynamic respiratory resistance method of testing clause without reference to iso standard at present, domestic
There is no corresponding mouth mask dynamic respiratory resistance test device.
