results of tests on the suit. This requirement does not apply to certain reusable items such as
coveralls, cloth hoods, cloth booties, rubber gloves, or rubber overshoes that are worn with
supplied-air suits.
Use of Individuals to Test Supplied-Air Suits
11.3.1 Testing should use three volunteer suit testers to determine the performance
of the supplied-air suit. Each of the three suit testers should be of a different
size. One suit tester should be selected from each of the following range of
heights: (a) 168 to 176 cm (5 ft 6 in. to 5 ft 9 in.); (b) 177 to 188 cm (5 ft 10
in. to 6 ft 2 in.); and (c) 191 to 198 cm (6 ft 3 in. to 6 ft 6 in.).
11.3.2 In the event that a supplied-air suit is designed for individuals meeting
specific requirements, i.e., minimum or maximum height and girth (chest
and/or stomach), the three suit testers should be selected to be representative
of the minimum and maximum range.
11.3.3 The height and the maximum girth (chest and/or stomach) of each of the
three suit testers should be determined and listed in the report containing the
results of the tests on the supplied-air suit.
11.3.4 Each suit tester must have successfully passed a medical evaluation as
required by the Occupational Safety and Health Administration (OSHA) in
29 CFR 1910.134.
Donning and Wearing of Supplied-Air Suit by Suit Tester
11.4.1 Before permitting a suit tester to don the supplied-air suit submitted by a
DOE contractor, a test operator should attach to the test subject a suitable
device that contains the appropriate probes and sensing elements for
measuring the performance characteristics of the supplied-air suit.
11.4.2 Before donning the supplied-air suit, the suit tester should don spectacles,
hearing protectors, and any other items needed for comfort or considered
necessary. The suit tester should don and wear the supplied-air suit in
accordance with instructions provided to the STF by the DOE contractor.
Determination of Airflow Indicator Accuracy
11.5.1 During a test of the airflow to the supplied-air suit, the rate of flow of air to
the suit should be determined at the minimum and maximum airflow rate
values specified by the DOE contractor for a particular length and inside
diameter of the breathing air hose. The air pressure in the breathing zone of
the suit tester wearing the suit should be measured at the minimum and
maximum specified values for airflow specified by the DOE contractor for a
particular length and inside diameter of breathing air hose.
11.5.2 The acceptable accuracy of the airflow and pressure indicators of the
supplied-air suit should be plus or minus 10 percent for each airflow rate
value and for the minimum and maximum lengths of breathing air hose.
