        coefficients examples
Annex F (normative) - Determination of Delta[eGc,l],
        based on a given P[QR]
Annex G (informative) - Sealing gasket parameter
        when no leakage rate is specified

        taking into account the plastic deformation
        of the gasket in subsequent load conditions
        procedures (after assembly)
Annex I (informative) - Available, incomplete models
        for conversion of the leakage rates in different
        conditions (based on certain flow models)
Annex ZA (informative) - Relationship between this
         European Standard and the Essential
         Requirements of EU Directive 97/23/EC
