Part 2 of this report shows that similar to an arrangement of the barrier layer cross to the pipe axis the addition of a so called shock wave absorber results in a comparable increase in limit pressure for safety against flame transmission through a barrier layer of crimped metal ribbon, especially in case of critical stresses, for instance when stressed by a stable detonation at instationary conditions, by an instable detonation at extreme instationary conditions and by a fast deflagration after shock waves have been pushed forward into the unburned gas. By variing some parameters like width of channels, geometry of channels, length of pipe, geometry of pipe, geometry of shock wave absorber, reactive gas phase etc., some general statements can be made about the limit of safety against flame transmission through barrier layers out of crimped metal ribbon flame arrester elements when stressed by detonative reactions of fuel gas/air- or fuel vapour/air-mixtures.
