TDA-99B Protective Mask Test System
Description
The TDA-99B Protective Mask Test System provides a broad range
of testing functions for military and commercial masks and
respirators. The system is very easy to use, with full data
management capabilities. The modular design enables testing
of virtually all protective masks and mask components to a
wide variety of test standards. The TDA-99B is ideal for use
in manufacturing plants, mask storage depots, cleaning/repair
facilities, and any other location where quality assurance
testing of masks and respirators is required.
The TDA-99B was designed to replace the antiquated military
M14 and commercial TDA-104, TDA-2ENB and TDA-101 test systems
that have been in widespread use for decades. The basic system
provides aerosol-based leakage testing of protective masks
with or without the filter canisters attached. Additionally,
the leakage isolation "probe" test enables the user to locate leaks
normally invisible to the naked eye so that repair/replacement
decisions can be made. The touch-screen interface and Microsoft Windows™ based control system provide maximum data management
flexibility. The TDA-99B also includes an integrated aerosol
purge and filtration system to eliminate the need for a fume
hood.
Optional Capabilities
In addition to the basic functionality described above, the
TDA-99B can also be configured to provide the following optional
protective mask testing capabilities:
Outlet Valve Test - The outlet valve can
be isolated for airflow leakage under tightly controlled pressure
and flow conditions.
Drink Tube Flow Test - The drink tube flow
and resistance are measured to determine if there is blockage
in the tube.
Drink Tube Valve Test - The drink tube valve
is tested for leakage under controlled pressure conditions.
Drink Train Leak Test - The entire drink
tube is tested for leakage under controlled pressure conditions.
Parallel Measurement - Dual detection systems
can provide parallel measurement of leakage in two areas of
the mask simultaneously, such as nose cup and eye lens area.
Hose Testing - Enables full leakage testing
of masks with air supply hoses.
Extra Test Heads - The base TDA-99B includes
one medium or small test head with an inflatable peripheral
seal. Additional test heads can be provided for testing an
extremely wide variety of full-face and neck-seal protective
masks.
Breathing Simulation - Although typical
leakage tests use a constant airflow under negative pressure,
the TDA-99B can be integrated with a full-function sinusoidal
breathing system to simulate a wide range of human respiratory
patterns.
Mil-Spec Mask Flexing - The
TDA-99B can easily incorporate Mil-Spec flexing
hardware and fittings, with full data logging capability and screen-by-screen Mil-Spec flexing instructions.
Since all TDA-99B Protective Mask Test Systems are made to
order, additional testing functionality and options can be
designed to meet your specific needs.
