DOE-STD-1167-2003
15.2
Test Procedure
15.2.1 A steady pull of 100 lb for 300 sec (5 min) should be made on the breathing
air hose and coupling.
15.2.2 The breathing air hose and coupling should be observed during the steady
pull. Any breaking of the hose, separation of the hose and coupling, and
separation of components of the coupling should be recorded.
15.2.3 The rate of airflow through the breathing air hose and coupling during the
steady pull should be observed. The lowest value of the rate of airflow
through the hose and coupling should be recorded. The maximum decrease in
the rate of airflow through the hose and coupling as a percentage of the
original airflow rate should be calculated and recorded.
15.2.4 A rapid pull of 100 lb of 0.5-sec duration or less should be made on the
breathing air hose and A total of three of these rapid pulls should
be carried out.
15.2.5 The breathing air hose and coupling should be observed after each of the
three rapid pulls. Any breaking of the hose, separation of the hose and
coupling, and separation of components of the coupling should be recorded.
15.2.6 The rate of airflow through the breathing air hose and coupling during each
of the three rapid pulls should be observed. The lowest value of the rate of
airflow through the hose and coupling during each rapid pull should be
recorded. The maximum decrease in the rate of airflow through the hose and
coupling as a percentage of the original airflow rate should be calculated and
recorded.
15.2.7 The procedures given in 15.2.1 through 15.2.6 should be carried out on the
breathing air hose and each type of coupling used.
15.2.8 The strength of the breathing air hose and couplings of the supplied-air suit
should be acceptable if, during the prescribed tests, breaking of the hose,
separation of the hose and couplings, and separation of components of
couplings do not occur and if the lowest rate of airflow through the hose and
couplings is not less than 90 percent of the original rate of airflow through
the hose and couplings.

16.1
Test Equipment and Requirements
16.1.1 The strength of the connection of the breathing air hose to the supplied-air
suit submitted by a DOE contractor should be determined by means of a test
involving a measure of the fit factor provided by the suit when the connection
of the breathing air hose to the helmet is subjected to a separating force. In
the test, a suit tester should wear the breathing air suit, which is connected by
means of the breathing air hose to a source of air, in an atmosphere
containing a test agent.
