This document details generic gasket parameters for use in EN 1591-
1 during preliminary calculations during which the type of gasket to be
used in an application is to be decided. Once the gasket type has
been decided the parameters for gaskets of that type from the
different potential commercial suppliers should be used in further
calculations as within a gasket type there will be differences
depending upon the supplier.
