assembly for a period of three minutes. The hose assembly shall meet the requirements specified
in 3.5.2.1.
4.3.2.2 Leakage. The connector of the hose assembly shall be fully engaged with the
specified proof assembly, and the other end of the hose assembly shall be capped. A static
pressure of 2.0 psig shall be applied to the assembly for a period of three minutes. The hose
assembly shall meet the requirements specified in 3.5.2.2.
4.3.2.3 Pressure drop.
4.3.2.3.1 Hose assembly (Drawing 286AS100). The specified proof assembly shall be
subjected to an air flow of 300 lpm with a back pressure of 1.5 inches of mercury, and the
pressure drop across the proof assembly shall be recorded as a tare value. The hose assembly
(Drawing 286AS100) shall then be fully engaged with the specified proof assembly and
incorporated into the same basic test apparatus. The pressure drop across the complete hose
assemblies shall be recorded when subjected to an airflow of 300 lpm with a back pressure of 1.5
inches of mercury. The hose assembly shall meet the requirement specified in 3.5.2.3.1.
4.3.2.4 Connector endurance. The connector of the hose assembly shall be cycled 1,000
times. The engagements and disengagements shall be conducted at the rate of one cycle per
three seconds using the specified proof assembly. A cycle shall constitute one complete
engagement and disengagement. Upon completion of the 1,000 cycles, the assembly shall meet
the requirements specified in 3.5.2.4. The hose assembly shall then be subjected to and pass the
flow check, leakage, and pressure drop tests.
