Abstract

Monitoring the temperature in a controlled layer of the sorptive material of a Filter of Gases Mask or of a Filter of Collective Protection we can conclude that the moment during which the potential of its sorption has been completed, as at this moment the inclination of the curve of the temperature becomes negative, due to the drop of its temperature. Knowing also how long is the distance of this layer from the termination of the layer of the sorptive material and knowing when the use of the Filter has started, the remaining time of rupture can be estimated.
