2.2 Hose Assembly Procurement Specifications:
Refer to AS6I4SUP1 for a listing of applicable hose assembly procurement standards applicable to this document.
3. TECHNICAL REQUIREMENTS:
3,1 Qualification:
Hose assemblies supplied in accordance with this document shall be representative of products
which have been subjected to and which have successfully passed the qualification tests specified in this standard.
Manufacturer Qualification: A manufacturer producing a product in conformance to this
procurement specification shall be accredited in accordance with the requirements of P02101.
AS7003 and AS71 12, and shall be listed in a Performance Review Institute (PRI) Qualified
Manufacturers List (QML).
3.1.2 Product Qualification: All products shall conform to the requirements of this procurement
specification and shall be approved in accordance with the requirements of PD2001, and P02101. for listing in a Performance Review Institute (PRI) Qualified Parts List (QPL).
3.2 Material:
The hose assembly materials shall be uniform in quality, free from defects, consistent with good
manufacturing practice and shall conform to applicable specifications and the requirements specified herein, and suitable for the purpose intended.
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 included in the compound from which the tube is extruded.
3.3.2 Reinforcement: The reinforcement shall consist of corrosion-resistant steel wires conforming to the applicable specifications listed in 3.2.1. The wires shall be so arranged over the inner tube as to provide sufficient strength to ensure conformance with 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 material 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 to withstanding temperatures of -65 to 400 °F and shall not extrude through the outer braid during testing or in service.
3.3.4 Fillings: All fittings shall be permanently attached and proven to meet the requirements herein. Standard hose assemblies shall have flared fittings to mate with AS4395 or flareless fittings according to NAS 1760 to mate with AS3351 4 or AS4375. Fitting hex portions shall fit standard wrench openings.
