Testing of airtightness

Testing of airtightness
 
According to
EN ISO 9237, DIN EN 12114, DIN 53120 Part 1 + 2
and other different national and international standards
 
Determination of  the  joint- capacity-coefficient (A-value) in accordance with DIN 4108-Part 7.
 
By the use of exactly defined cross sectional areas miscellaneous differential pressures can be produced.
 
The air permeability R [m/s] aswellas the joint- capacity-coefficient  (A-value) is calculated with the resulting flow quantities of the air.
