Test for Crush Resistance of Breathing Air Hose
Up
DOE Standard Respiratory Acceptance Program for Supplied
Next
Strength of Connection of Breathing Air Hose to Supplied-Air Suit


DOE-STD-1167-2003
14.1.4 A 6-ft-diameter single-coil loop of the breathing air hose should be formed
with the loop on a horizontal surface.
14.1.5 At a distance of 3 ft from the single-coil loop, one of the sections of the
breathing air hose, which extends from the loop and which leads to the source
of compressed air, should be securely fastened to the horizontal plane
surface.
14.2
Test Procedure
14.2.1 The portion of the breathing air hose that extends from the single-coil loop,
and which is not fastened to the horizontal plane surface, should be slowly
pulled parallel to the horizontal plane surface. The hose should be held by the
attached fittings and pulled until the loop unfolds and the hose straightens
out.
14.2.2 The rate of airflow through the breathing air hose should be observed during
the time that the single-coil loop of the hose is unfolded and the hose is
straightened out. The lowest value of the rate of airflow through the hose
during the hose-straightening process should be recorded. The maximum
decrease in the rate of airflow through the hose as a percentage of the original
flow rate should be calculated and recorded.
14.2.3 The way in which the single-coil loop of air hose unfolds should be observed,
and a record should be made of any localized kinking of the hose.
14.2.4 The breathing air hose should be acceptable in regard to resistance to kinking
if, during the process of unfolding the single-coil loop of hose, the lowest rate
of flow of air through the hose is not less than 90 percent of the original rate
of airflow through the hose and if localized kinking of the hose does not
occur.
15.0
Test for Strength of Breathing Air Hose and Couplings
(Does not apply to hoses that do not incur any significant pulling during use, i.e., hoses within the envelope of the supplied-
air suit)
15.1
Test Equipment and Requirements
15.1.1 The strength of the breathing air hose and couplings of the supplied-air suit
submitted by a DOE contractor should be determined by two tests. If more
than one type of coupling is used in the suit, then a length of breathing air
hose with each type of coupling should be tested.
15.1.2 The breathing air hose and coupling should be connected to a source of
compressed air, and a calibrated airflow-measuring instrument should be
used to monitor the rate of airflow through the hose and coupling. The rate of
airflow through the breathing air hose and coupling should be adjusted to the
minimum value specified by the DOE contractor.
