Test Principle

Vacuum pump provides test product power source
Internal and external pressure measurement using tooling and fixture with built-in differential pressure sensor
All-in-one machine case with built-in vacuum pump and digital display meter for automatic pressure detection and display
Equipped with special jig for convenient product testing

Standard Requirements

Number of samples: 5
Test process: Gas flow rate adjusted to 8L/min, sample test area diameter 25mm, test area 4.9cm²
Test results: YY0469-2011 and YY/T0969-2013 standards require ventilation resistance (pressure difference of gas exchange between mask sides) not greater than 49Pa/cm² for total gas exchange

△P = M/A
Where:
△P - Experimental sample area pressure difference per square centimeter (Pa/cm²)
M - Experimental sample pressure difference (Pa)
A - Experimental sample test area (cm²)
