39、quired, to meet the construction and performance requirements of this document. 3.3.1 Inner Tube The inner tube shall be of a seamless construction of virgin PTFE resin of uniform gage. It shall have a smooth bore and shall be free from pitting or projections on the inner surface. Additives may be i
40、ncluded in the compound from which the tube is extruded. 3.3.2 Reinforcement The reinforcement shall consist of corrosion resistant braid(s) and/or wraps conforming to the applicable material specification listed in 3.2.1.2. The reinforcement shall be arranged over the inner tube to provide sufficie
41、nt strength and protection for ensuring conformance to the requirements specified herein. Broken reinforcing wires shall be cause for rejection. Crossed-over reinforcing wires shall not be cause for rejection of the hose assembly. 3.3.3 Interlayers Interlayers, if used, shall be of a suitable materi
42、al and shall be resistant to pressure pounding and to all fluids with which the hose may come in contact during normal service. They shall be capable of withstanding temperatures of -65 to 400 F (-54 to 204 C) and shall not extrude through the outer braid during testing or in service. 3.3.4 Fittings
43、 All fittings shall be permanently attached and proven to meet the requirements herein. Standard hose assemblies shall have flareless fittings according to NAS 1760, AS4458, or equivalent, to mate with AS5827, or dynamic beam seal fittings to mate with male end per AS85720/1 or AS4207. Anti-torque h
44、exes or flats shall be provided and shall fit standard wrench openings. All internal surfaces of fitting nuts and retaining wire, when used, shall be dry filmed with dry film per AS5272. Dry film on external surfaces and overspray is not cause for rejection. SAE AS5960B Page 7 of 27 3.3.4.1 Straight

For elbow fittings, the inside diameter corner shall be a radius in accordance with ARP4266. 3.3.4.2 End Fitting Collars (Sockets) All end fitting collars (sockets), crimped or swaged,
46、and fabricated from Type 304 stainless steel are required to be capable of passing an embrittlement test as specified in ASTM A 262 Practice E, prior to assembly to the nipple and crimp or swaging operation. Sockets fabricated from stabilized austenitic steel (304L, 321, or 347) and titanium are acc
47、eptable without being subjected to the embrittlement test. Titanium collars, if used, shall be per ASTM B 348 - Grade 2. 3.3.5 Finish 3.3.5.1 Corrosion Resistant Steel Fittings Unless otherwise specified, corrosion resistant steel fittings shall be passivated in accordance with AMS2700 or AMS-QQ-P-3
