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 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 PD21O1.
AS7003 and AS7112, 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 PD21O1, 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, shall conform to applicable specifications and the requirements specified herein, and suitable for the purpose intended.
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.
Fillings: All fittings shall be permanently attached and proven to meet the requirements herein.
