6、a Five Year Review and update of this specification. 1. SCOPE 1.1 Form This specification covers an aluminum alloy in the form of extruded bars, rods, and shapes. 1.2 Application This product has been used typically for structural applications requiring material with high strength and resistance to
7、exfoliation-corrosion, but usage is not limited to such applications. 1.2.1 Certain design and processing procedures may cause these products to become susceptible to stress-corrosion cracking; ARP823 recommends practices to minimize such conditions. 2. APPLICABLE DOCUMENTS The issue of the followin
8、g documents in effect on the date of the purchase order forms a part of this specification to the extent specified herein. The supplier may work to a subsequent revision of a document unless a specific document issue is specified. When the referenced document has been cancelled and no superseding do
9、cument has been specified, the last published issue of that document shall apply.
