Principle:
The subject wearing the article filtering half mask under test walks on a treadmil over which is an enclosure.Through this enclosure flows a constant concentration of NaCI aerosol. The air inside the particle filtering half mask is sampled and analysed during the inhalation hase of the respiratory cycle to determine the NaCI content. The sample is extracted by punching a hole in the particle filtering half mask and inserting a probe through which the sample is drawn. The pressure variation inside the particle filtering half maskk is used to actuate a change-over valve so that inhaled air only is sampled , a second probe is inserted for this purpose.
