This document is Exhibit A to a federal contract (N0010425RX19780) establishing data requirements and material certification standards for seamless nickel-copper alloy pipe (1IN diameter) supplied to Portsmouth Naval Shipyard.

The exhibit specifies two primary data item requirements: Material Certification (Data Item A001) and Procedure Approvals (Data Item A002). Material certification must be supplied with each shipment and shall include a Certificate of Compliance attesting to full compliance with all contract requirements, supported by original or exact copies of quantitative or qualitative test reports from the testing organization. All certifications must identify the contract number, heat/lot number, and vendor traceability number. For chemical analysis certification, vendors must provide photostatic copies of original test facility certifications including complete chemical test analysis results. For mechanical properties certification, vendors must provide photostatic copies of original test facility certifications showing actual test data for tensile strength, yield, elongation, reduction in area, and hardness; when material undergoes heat treatment, forging, or cold working, the certification must be annotated with traceability number, heat number, heat treat number, and authorized company representative signature. For seamless certification, vendors must include a specific statement confirming the material is seamless. Procedure approvals must be submitted to Portsmouth Naval Shipyard (PNSY) prior to performing applicable tests. A sample Certificate of Compliance template is provided detailing required material identification fields including contract number, delivery order, item number, national/local stock number, manufacturer's part and serial numbers, drawing and piece number, and manufacturer's lot/heat number.
