Requirements and testing for expanded-graphite gasket sheets, used together with DIN 28091-1.
This is a gasket-sheet specification. Coverage of a commercial formulation depends on its product classification; it does not automatically certify material used as spiral-wound filler. Numerical requirements remain — because the applicable table values have not been verified.
