For the TA Luft(1) test, the seal is installed in a DN40/PN40 steel flange, usually with a gasket stress of 30 MPa. The flange is then exposed to a defined temperature for minimum 48 hours. After cool down, leakage rate is measured over a period of at least 24 hours. The test pressure is 1 bar helium.
The ultimate final leakage rate after a test duration of 24 hours must remain below 10–4 mbar*l/(s*m) for the seal to qualify according to TA Luft.
No test procedure currently exists for glass-lined steel. Therefore Gore has conducted modified tests for this certification. A DN200/PN10 steel flange with a gasket stress of 25 MPa was utilized.
TA Luft certificate is available for thickness 6 mm.
