3.3.2 Proof pressure. Hose assemblies when tested in 4.5.2 shall withstand the applicable hydraulic
proof pressure specified in table I without separation at the hose-to-adapter interface or without showing
evidence of imperfections. There shall be no evidence of leakage or damage to the hose or adapters.
3.3.3 Bulge. Hose assemblies when tested in 4.5.3, the bulge of the elastomeric tube of the hose
shall not reduce the inside diameter (ID) of the hose to less than the C dimension shown on figure 1.
3.3.4 Leakage. Hose assemblies when tested in 4.5.4 shall withstand 70 percent of the burst
pressure specified in table I. The hose assembly shall show no evidence of leaking of the hose or the
hose to adapter interface, deformation or damage to the hose or adapters, or adapter movement relative
to the hose.
3.3.5 Burst pressure. Hose assemblies when tested in 4.5.5 shall not burst, separate at the hose-to-
adapter interface, or leak at any pressure up to the burst pressure specified in table I.
