TA Luft test in accordance with VDI 2200 (06-2007)

For the TA Luft1 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.

TA Luft certificates are available for thicknesses 1.5 mm, 3 mm and 6 mm.

The Federal Institute for Materials Research and Testing (BAM) tests the sealing material compatibility for use in flanged connections with liquid and gaseous oxygen. Further information on the test procedure and the result can be found in the following test report.

Eurochlor's publication on Experience of Gaskets in Liquid Chlorine and Dry or Wet Chlorine Gas Service and the Chlorine Institute's Pamphlet 95 Gaskets for Chlorine Service cover gaskets for both dry and wet chlorine service and highlight materials that have found user acceptance through field-testing and member company experience. GORE GR Sheet Gasketing and GORE® Universal Pipe Gasket (Style 800) are both listed in these publications. The documents are available from the respective organizations.

GORE GR Sheet Gasket has received a Product Design Assessment (PDA) Certificate per the ABS Type Approval Program.

This test analyzes leachable water-soluble fluoride and chloride ions which can induce flange corrosion. The samples are leached for 24 hours at approximately 95°C in demineralized water. Contact Gore for further information if this testing is required for your application.

GORE® Gasketing products meet the definition of an article; therefore, a Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) is not required. However, for your convenience, a Product Safety Sheet, which details the intended use and proper handling of our articles, is provided.

The Gore Sealant Technologies Quality Management System is certified in accordance with ISO 9001.
