Test for Crush Resistance of Breathing Air Hose


DOE-STD-1167-2003
of the airflow and the moment that the aerosol penetration reaches values of
0.05 percent, 0.1 percent, and 1 percent. The test operator then should restore
the flow of air to the supplied-air suit, while the suit tester remains standing
still with his arms hanging downward along his sides breathing normally until
the aerosol penetration returns to the value occurring before the flow of air
was terminated.
For supplied-air suits equipped with an escape feature, the supplied-air suit
shall be tested with the flow of air stopped as the suit tester uses the escape
feature while standing still with his arms hanging downward along his sides.
The test operator should observe the increase in penetration of the aerosol
into the helmet of the supplied-air suit, and record the time between the
termination of airflow and the moment that the aerosol penetration reached
the value of 0.05 percent, 0.1 percent and 1 percent or 3 minutes, whichever
is first achieved. The test operator then should restore the flow of air to the
supplied-air suit and the suit tester should remain standing still with his arms
hanging downward along his sides and breathe normally until the aerosol
penetration returns to the value occurring before the flow of air was
terminated.
12.2.6 Determine the average of the peak aerosol penetration values that occurred
during each of the exercises listed in 12.2.2, and record these average peak
penetration values.
12.2.7 Using the values determined in 12.2.6, calculate the average peak penetration
for all exercises carried out by each suit tester.
12.2.8 If required, repeat 12.2.2 through 12.2.7 for maximum and minimum rates of
airflow and length of breathing air hose (if more than one length of hose is
used to connect the supplied-air suit to the supply manifold) specified by the
DOE contractor.
12.2.9 Repeat 12.2.1 through 12.2.8 for each of the suit testers.
12.2.10 If the supplied-air suit is reusable or a part of it is laundered; a reused or
laundered supplied-air suit or part submitted by the DOE contractor should
also be tested in accordance with 12.2.1 through 12.2.9.
12.2.11 The suit should be acceptable in regard to providing respiratory protection if
the average peak aerosol penetration into the helmet of the supplied-air suit
of each test subject does not exceed 0.02 percent for any individual exercise
or does not exceed 0.01 percent for all exercises. This should be true for all
values of the rate of airflow and hose length into the supplied-air suit ranging
from the minimum value to the maximum value specified by the DOE
contractor. For assigned protection factors in excess of 10,000, the values of
0.02 and 0.01 percent aerosol penetration shall be adjusted in proportion. For
example, for a protection factor of 20,000, the value of peak penetration for
any exercise should be 0.01% and for all exercises 0.005%.
