Consistent with FAR 52.216-18, all contractual documents (i.e. contracts, purchase orders,task orders, delivery orders and modifications) related to the instant procurement are considered to be "issued" by the Government when copies are either deposited in the mail, transmitted by facsimile, or sent by other electronic commerce methods, such as email. The Government's acceptance of the contractor's proposal constitutes bilateral agreement to "issue" contractual documents as detailed herein. 5. Submission of all certification DD1423 Data Contract Data Requirements Lists (CDRLs) will be on or before 20 days prior to delivery. PNSY Review/Acceptance of certifications CDRLs 6 working days after receipt of certification DD1423 CDRLs. Final delivery of material will be on or before 270 days after contract effective date. 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. 2.2.1 Documents, drawings, and publications supplied are listed under "Drawing Number". These items should be retained until an award is made. 2.2.2 "Document References" listed below must be obtained by the Contractor. Ordering information is included as an attachment to this contract/purchase order. 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.
