IN THE EMU CLASS THREE LAB

3
00:00:05,505 --> 00:00:07,040
IS USED TO PROVIDE A SIMPLE

ENGINEERING EVALUATION

5
00:00:08,475 --> 00:00:10,443
OF GLOVES AND OTHER HARDWARE.

FROM THE CURRENT ISS SUIT,

21
00:00:31,331 --> 00:00:32,198
THE TEST SUBJECT CAN

22
00:00:32,198 --> 00:00:34,033
EVALUATE THE FIT OF THEIR GLOVES

23
00:00:34,033 --> 00:00:35,502
AND MAKE QUICK CHANGES,

24
00:00:35,502 --> 00:00:36,770
OR ASSESS NEW HARDWARE

25
