THE FOLLOWING CLAUSE IS HEREBY INCORPORATED: CONTRACT CLAUSE FOR PROTECTION OF NAVAL NUCLEAR PROPULSION INFORMATION During the performance of this contract Naval Nuclear Propulsion Information(NNPI (NOFORN)) may be developed or used. Naval Nuclear Propulsion Information is defined as that information and/or hardware concerning the design, arrangement, development, manufacturing, testing, operation, administration,training, maintenance, and repair of the propulsion plants of Naval NuclearPowered Ships, including the associated shipboard and shore-based nuclear support facilities. Appropriate safeguards must be proposed by the contractor, and approved by the Contracting Officer for Security for the safe guarding from actual, potential,or inadvertent release by the contractor, or any subcontractor, of any NNPI(NOFORN) in any form, classified or unclassified. Such safeguards shallensurethat only governmental and contractor parties, including subcontractorsthat have an established need-to-know, have access in order to perform workunder this contract, and then only under conditions which assure that theinformationis properly protected. Access by foreign nationals or immigrantaliens is not permitted. A foreign national or immigrant alien is defined as aperson not a United States citizen or a United States national. United Statescitizens representing a foreign government, foreign private interests or otherforeign nationals, are considered to be foreign nationals forindustrialsecurity purposes and the purpose of this restriction. In addition, any and all issue or release of such information beyond such necessary parties, whether or not ordered through an administrative orjudicial tribunal, shall be brought to the attention of the ContractingOfficer for Security. The Contracting Officer for Security shall be immediately notified of anylitigation, subpoenas, or requests which either seek or may result in therelease of NNPI (NOFORN). In the event that a court or administrative order makes immediate review by the Contracting Officer for Security impractical, the contractor agrees totake all necessary steps to notify the court or administrative body of theNavy's interest in controlling the release of such information through reviewand concurrence in any release. The Contracting Agency reserves the right to audit contractor facilities forcompliance with the above restrictions. Exceptions to these requirements may only be obtained with prior approval fromthe Commander, Naval Sea Systems Command (SEA 09B2). Additional guidance maybe obtained from NAVSEA Instruction 5511.32 \ 1. SCOPE 1.1 The material covered in this contract/purchase order will be used in a crucial shipboard system. The use of incorrect or defective material would create a high probability of failure resulting in serious personnel injury, loss of life, loss of vital shipboard systems, or loss of the ship itself. Therefore, the material has been designated as SPECIAL EMPHASIS material (Level I, Scope of Certification, or Quality Assured) and special control procedures are invoked to ensure receipt of correct material. 2. APPLICABLE DOCUMENTS 2.1 Order of Precedence - In the event of a conflict between the text of this contract/purchase order and the references and/or drawings cited herein, the text of this contract/purchase order must take precedence. Nothing in this contract/purchase order, however, must supersede applicable laws and regulations unless a specific exemption has been obtained. 2.2 Applicable Documents - The document(s) listed below form a part of this contract/purchase order including modifications or exclusions. 2.3 Specification Revisions - The specification revisions listed under "Docu ments References" below are the preferred revision. Older and/or newer r evisions are acceptable when listed within Contract Support Library Reference Number CSD155 in ECDS (Electric Contractor Data Submission) at: ht tps://register.nslc.navy.mil/. This is to allow Contractors to use certain acceptable older specification revisions to purge their existing stock of material certified to those older revisions or to use newer specification revisions when material is certified to newly released revisions,without requiring the submittal of waiver/deviation requests for each specification revision on every contract. Revisions of specifications reflecting editorial and/or re-approval (e.g. E2009, R2014, etc.) are considered inconsequential, but are acceptable when their revisions are listedwithin CSD155 or elsewhere within this contract. 2.3.1 "Document References" listed below must be obtained by the Contractor. Ordering information is included as an attachment to this contract/purchase order. 2.3.2 Documents, drawings, and publications supplied are listed under "Drawing Number".

This traceability marking on the material shall provide direct traceability to the material's chemical composition and mechanical properties certification data. For material produced by batch, continuous cast, or continuous pour processes, samples shall be taken no less than once in every eight hours of operation for the purpose of validating proper chemical composition and mechanical properties. Traceability shall be maintained through all process operations including any subcontracted operations, to the finished component. 3.21.1 Material Marking for Traceability and Identification - The following are the minimum marking requirements. Additional/alternate marking requirements, if applicable, will be specified elsewhere in the contract/purchase order. In addition to the marking requirements on applicable drawings and/or specifications, marking for traceability is required. All traceability markings shall be permanently applied in accordance with MIL-STD-792 (except as specified below). An alternate marking method is permissible provided it is an available option in the contractually invoked specification or drawing, except in instances where the material has been modified by this contract/purchase order and differs from that specified in the specification or drawing. 3.21.2 Traceability markings for items with precision machined or plated surfaces, or material with suitable marking surface areas less than 3/8 inches square (either 3/8" x 3/8" or an area equal to 0.1406 inches square) shall be applied to a durable tag and the tag securely affixed to the material. 3.21.3 Permanent marking shall be legible and shall be located so as to not affect the form, fit, and function of the material. ;Balls must be marked in the airway and seats must be marked on the outer cylindrical surface.; 3.21.4 Seat Marking - Each seat must be permanently marked in accordance with MIL-STD-792, type I and as stated below, except for Teflon seats, which shall only be tagged. Type IX marking may be substituted for type I, provided the minimum character size scribed by the marking tool shall be approximately 3/32 inch high to insure legibility. Permanent marking is not permitted on Teflon seats. Seat marking requirements shall maintain complete traceability to certification OQE. Seat marking shall be either heat/lot or batch number, a vendor traceability number/code, or a combination thereof and shall be unique to the material certification. 3.21.5 Traceability markings shall be maintained through assembly, and whenever possible shall be visible after assembly. For items where the marking is not visible after assembly, a durable tag shall be securely attached to the item identifying the part number, piece number, traceability number, and the location of the permanent mark. 3.22 See CDRL-DI-MISC-81020 (Chemical and Mechanical) and CDRL DI-MISC-80678 (SEAT MATERIAL) - Material Certifications - The following material certification requirements apply: 3.22.1 Metallic Material - Quantitative chemical and mechanical analysis of material traceable to traceability markings is required. Material certification test reports shall include the class, form, condition, grade, type, finish, and/or composition, as applicable, of the material supplied. 3.22.2 Non-Metallic Material - The Contractor shall furnish the applicable test reports for each heat/lot/batch of seat material. Material certification test reports shall include, in addition to the specification, the class, form, grade, type, process, and/or composition, as applicable, of the material supplied. 3.22.3 Re-identification and re-certification of metallic material is required when the material is subjected to a process which alters its properties. If the starting material or raw stock is processed in a manner that will not affect its chemical composition or mechanical properties, the original certifications for the chemical composition and mechanical properties, as required by the material specification, are acceptable. Re-certification of the chemical or mechanical properties is required if a process is used during fabrication...
