SWISS AF CBW TESTED EQUIPMENT
In the late 80's early 90's, Swiss AF evaluated a number of Chemical/ Biological Warfare (CBW) pilot protective systems.
The main evaluation criteria the chem/bio protection effectiveness and the compatibility/ integration with Swiss AF aircrew and aircraft operations.
Because of the test results, most likely also for technical, logistical and financial reasons, none of the evaluated systems was put into service.
Below a list and links to some of the equipment tested.
Although not included in the tests, the MBU-13/P full-face mask - CRU-80 /P filter combo was considered as an "off the shelf" option in order to have comparative parameters.
