TM 1-1500-204-23-2 Figure 4-35. Nonself-Sealing, Aromatic and Heat-Resistant Hose, MIL-H-6000 Figure 4-36. Flame Aromatic, and Oil-Resistant Hose MIL-H-7938 NOTE Whenever operating pressure of a hose as- sembly is unknown, it will be assumed to be 1500 psi or greater (a) Below30psi. For hose assemblies used as vents and hose assemblies which operate below 30 psi, excessive wire damage as described herein will not apply. Replacement of these assemblies will be at the discretion of the local inspector/mechanic using good shop practice and experience. (b) Below 500 psi. For hose assemblies which operate below 500 psi, excessive wire damage consists of four or more broken wires In a single plait, 12 or more broken wires per assembly or per lineal foot whenever assemblies exceed 12 inches in length. (c) Above 500 psi. For hose assemblies which operate at 500 psi and above, excessive wire damage consists of two or more broken wires In a single plait, two or more adjacent wires, one or more broken wires in an area where kinking is suspected, six or more broken wires per assembly or per lineal foot whenever assemblies exceed 12 inches. Crossed reinforcing or random broken wires are not causes for rejection. (5) Leakage. Hose assemblies will be replaced when leakage occurs with hydraulic pressure applied. (6) Static leakage. With no pressure applied, leakage exceeding one drop per hour will be cause for replacement of the assembly. (7) Abrasion, kinking, distortion, bulging, col- lapse, or sharp bending. Any evidence of these con- ditions will require replacement of hose assemblies NOTE Hoses need to be changed for abrasion only If the metal reinforcement is exposed (this note does not apply to braided wire covered hoses). (8) Internal damage. Inspect internal restric- tin due to collapse, wire braid puncture, or other damage by one of the following methods. 4-37
