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).
