VDI 2200 (TA LUFT) FLANGE SEALS
DETERMINATION OF LEAKAGE LEVEL FOR FLAT GASKETS
A stand used for the determination of leakage in flat gaskets. The results are compared with the requirements of the VDI 2200 and TA-Luft requirements and – if fulfilled – the laboratory issues a certificate of conformity with the TA-Luft regulations. After holding a clamped flange joint in a temperature dependent on the gasket material for 24 hours, the leak-tightness test is conducted in room temperature. The pressure of the medium (helium) is 1 bar. The measurement of the leakage is performed by vacuum method using a helium spectrometer.
