The gasket characteristics published in this database are approved by the European Sealing Association (ESA). The ESA is operating the database ESAdata.org as a service for our members and for general industry. The data is independently verified from each manufacturer to ensure consistency and accuracy.
This is a developing database and the first phase of the programme is limited to gasket characteristics according to EN 13555 which are required for flange calculations according to EN 1591-1. The database will be developed to include additional characteristics (e.g. HOBT, ROTT, m & y, etc.) in future releases.
