Certified Material Test Reports Certified test reports for chemical analyses, mechanical properties and physical tests reports showing actual results of all testing invoked by the applicable specification, drawing or purchase order are required to be submitted and shall be those issued by the original producer of the material which certify conformance to the specification(s). All certified test report data shall be recorded on the testing company's letterhead and bear the name, title and signature of the authorized representative of the company. In cases where the producer or melt source is not a domestic source, the country of origin shall be indicated on the test report, or if not identified, annotated on the test report by the supplier. If the producer or melt source is a domestic source, the test report shall be clearly indicated as such, or annotated on the test report by the supplier as produced or melted by a domestic source (United States of America). When multiple tests are required, the results of each test shall be reported. Test reports shall be identified with the buyer's purchase order number, item number, material specification/revision (including composition, type, class, grade, or condition) as applicable and indicate the same heat or traceability number that is marked on the material supplied. If mechanical tests are not performed on material in the final form or condition, the test reports must indicate the form, condition, and/or point in the manufacturing process that these tests were performed. If the material receives subsequent processing (i.e. heat treat, hot or cold forming/working, etc.) by the supplier or his sub-tier supplier(s) to make it conform to the required specification, the test reports for the material in its final condition (as supplied to the buyer) shall be accompanied by a copy(ies) of the original producer's certification(s). Where the number of test specimens is dependent upon the original total lot size, the vendor shall identify the original total lot size in addition to the quantity shipped to allow verification during independent review that adequate tests were performed. All tests and inspections required by the specification must be performed and records thereof maintained by the seller. However, reports for only those tests requested above or elsewhere within this purchase order shall be forwarded with the shipment. The test report(s) shall be attached to the packing list and secured to the package/container. If the packing list and the test report(s) are placed inside a package, their location shall be indicated on the exterior of the package. Test report(s) are required for each shipment.

105. Specialty Metals Certification of Conformance This purchase order incorporates a specialty metals clause. The supplier shall issue a Certificate of Conformance that shall include a statement of compliance with the Specialty Metals Clause incorporated in the purchase order. Note: For Suppliers of raw material(s) only (plate, bar, rounds, sheet, strip, etc.), mill heat reports or material certifications that clearly state the country of melt meet the requirement of this clause. Upon request, the supplier and its sub-tier suppliers shall provide NGES-MS with objective evidence of compliance with specialty metal requirements. 106. Certification of Shelf Life IAW MIL-HDBK-695 The Seller shall issue a certification of conformance confirming that all O-rings, gaskets, packings or other elastomeric products in components or sub-assemblies furnished under this purchase order are installed prior to expiration of their shelf life. Shelf life requirements are specified in the latest revision of MIL-HDBK-695 (Military Standardization Handbook, Rubber Products: Recommended Shelf Life). Certification to this quality code applies only to elastomers listed in MIL-HDBK-695 The Seller may determine that none of the elastomers furnished under this purchase order are listed in MIL-HDBK -695. Regardless, the Seller shall issue a certification of conformance confirming compliance with the shelf life requirements of this quality code. 107. Nondestructive Test (NDT) – Time of Acceptance Unless otherwise stated in the quality requirements notes in the purchase order, the drawing, or the approved inspection test plan, non-destructive test acceptance shall apply in the final surface and heat treated condition. There are two cases where “Time of Acceptance” needs to be clarified. The two cases are:

1. When a weld or cast surface is machined, ground or otherwise altered, and NDT requirements ARE shown on the drawing the supplier shall perform NDT of the altered weld or cast surface(s), along with all other surfaces specified by the drawing, in the final heat treated and machined condition, in accordance with drawing requirements. This requirement also applies in the case where a weld or cast surface is inadvertently machined and the drawing does not specify altering the weld or cast surface.

2. When a weld or cast surface is machined, ground or otherwise altered, and NDT requirements ARE

NOT shown on the drawing the supplier shall review the lower level drawing(s) to obtain NDT requirements and shall perform NDT of the altered weld or cast surface(s) in the final heat treated and machined condition in accordance with the lower level drawing.

a. For example, a machining drawing may not specify NDT. A weld may be inadvertently

machined. The Supplier would then review the fabrication drawing which specified the welding to obtain NDT and acceptance criteria requirements.

When this note is applied to the purchase order it is recommended that the supplier contact NGSC-MS for guidance.
