 For mine the pressure test was -.3 and +3 bars.  That is in a vacuum and also in compressive pressures.

Deformation was the amount of flex in the case

Tightness value same as strain trend is the % Micrometers per min of deformation.

Strain is the same as deformation, the amount of strain an object exhibits with a given stress (force, pressure, etc).

Look up stress strain curves and that may explain material interaction a little better.
