>> THE GLOVEBOX LOCATED
IN THE EMU CLASS THREE LAB
IS USED TO PROVIDE A SIMPLE
ENGINEERING EVALUATION
OF GLOVES AND OTHER HARDWARE.
INSIDE THE GLOVEBOX,
A NEGATIVE PRESSURE
IS REACHED AND MAINTAINED
AT A SPECIFIC
PRESSURE DIFFERENTIAL.
THIS SIMULATES THE PRESSURE
DIFFERENTIAL THE ASTRONAUT
EXPERIENCES INSIDE THE EMU
IN THE VACUUM OF SPACE,
WHILE STILL ALLOWING
THE TEST SUBJECT TO REMAIN
AT AMBIENT PRESSURE.
USING A PAIR OF CLASS THREE
ARMS AND GLOVES
FROM THE CURRENT ISS SUIT,
THE TEST SUBJECT CAN
EVALUATE THE FIT OF THEIR GLOVES
AND MAKE QUICK CHANGES,
OR ASSESS NEW HARDWARE
AND TOOLS WITHOUT THE NEED
TO PRESSURIZE A FULL SUIT.
