1) VU=Minimum assembly pressure (adaption) at room temperature (RT)
2) VO=Maximum assembly pressure at RT
3) m=Ratio of "Minimum gasket pressure under operating conditions BU " to "Operating pressure = Internal pressure pi ", thus: m = BU/pi
4) BO=Maximum gasket pressure under operating conditions at various temperatures
5) bD=Effective sealing width in mm
6) Rz16 µm
7) Rz25 µm
