3 Terms and definitions
GB/T 5823 established and the following terms and definitions apply to this standard.
3.1
Pressure difference pressuredifference
The surface of the specimen on both sides of the absolute pressure difference by the air. When the specimen outside (outdoor) gas pressure is greater than the inside (indoor) gas pressure
, The pressure difference is set as a positive value, and vice versa.
3.2
Tightness airpermeabilityperformance
Blinds in the closed state, the ability to prevent air infiltration.
3.3
Test specimen air volume volumeofairflowthroughspecimen
In the reference state, the amount of air passing through the blinds specimen per unit time.
3.4
The amount of air per unit volumeofairflowthroughaunitarea
In the reference state, the unit of time through the blinds per unit area of the air volume.
3.5
Specimen area extrnalareaofspecimen
The maximum orthographic projection area when the shutters are closed.
3.6
Standard status standardcondition
Temperature 293K (20 ℃), the pressure of 101.3kPa, the air density of 1.202kg/m3 test conditions.
4 test methods
4.1 principle
When there is a pressure difference on both sides of the closed shutter, air infiltration will occur from the high-pressure side to the low-pressure side. The volume of air permeation
Blinds are the airtight performance. This test is made by making different positive pressure differential on both sides of the shutter under laboratory conditions
(ΔP), and measure the value of air permeability per unit area (q) under different positive pressure difference (ΔP), and find out the relationship between pressure difference and air per unit area
The relationship between the amount of penetration, louis vuitton, louboutin pas cher
Note. The test does not consider the shutter temperature difference between inside and outside the low pressure difference caused by the test results.
