Use
at temperatures below -50 °C is possible, if surface pressure is not
less than approx. 15 N/mm² in liquids or 30 N/mm² in gases (internal
pressure must be taken into account). In addition, the gasket must not
be subjected to bending or flexing stresses. At temperatures below -100
°C, operating pressures may not be higher than the max. values given
for -100 °C.
