Test Procedure - doe-std-1167-20030025

DOE-STD-1167-2003

16.1.2 A description of the aerosol, the instrumentation, and methods that should be

used to measure the penetration of the aerosol into the breathing zone of the

suit tester is given in 12.1.2 through 12.1.7.

16.1.3 A length of breathing air hose should be used, and all of the three suit testers

should be tested. The length of the breathing air hose should be adequate to

permit the carrying-out of the procedure described in 16.2.

16.1.4 The suit tester, wearing the supplied-air suit upon entering the test chamber,

should connect the breathing air hose to a fitting located inside the chamber

that is connected to a source of air. The suit tester, upon entering the test

chamber, also should connect the tubing from the probe inside the helmet of

the supplied-air suit to a fitting that is connected to the aerosol detection

equipment.

16.1.5 The test operator should adjust the rate of flow of air going to the supplied-air

suit worn by the suit tester to the minimum airflow rate value specified by the

DOE contractor. The test operator should check the operation of the aerosol-

monitoring equipment and make any necessary adjustments.

16.2

Test Procedure

16.2.1 The suit tester should walk at a normal pace away from the point where the

breathing air hose of the suit is connected to a fitting located inside the

chamber. The suit tester should continue to walk until stopped by the limited

length of the breathing air hose. The suit tester should stand still, while

keeping a steady tension on the taut breathing air hose, for at least 120 sec (2

min) or until the penetration of aerosol into the supplied-air suit helmet

shows no further increase.

16.2.2 The test operator should determine the average of the peak aerosol penetration

values, which occurred while the suit tester kept a steady tension on the taut

breathing air hose, and record this value.

16.2.3 The strength of the connection of the breathing air hose to the supplied-air suit

should be acceptable if the average peak penetration of the aerosol into the

helmet in the breathing zone of the suit tester, which occurred while the suit

tester maintained a steady tension on the taut breathing air hose, does not

exceed 0.02 percent.

17.0

Noise Test

17.1

Test Equipment and Requirements

17.1.1 The level of noise generated by the flow of air into the helmet of a supplied-

air suit should be less than 80 dBA when measured within three inches of the

test subject's ear while the supplied-air suit is worn following the DOE

contractor's instructions, with the shortest length of breathing air hose

permitted, and with minimum and maximum air volumes permitted.
