Reference (a) proposal exception #2 requests approval to use VACCO Industriesdrawing V3D10064 Revision M in lieu of V3D10064 Revision K. In response, VACCO Industries drawing V3D10064 Revision M is approved for thesubject solicitation and future contracts. VACCO Industries drawing V3D10064Revision M is already invoked by N00104-19-Q-FB99 Amendment 0001. 2. Reference (a) proposal exception #3 states that the material type for the Sleeve, Item11, as listed in paragraph 3.2 of the subject solicitation should be Type 304 in lieu ofType 309. In response, NAVSEALOGCEN comments that N00104-19-Q-FB99 Amendment0001, paragraph 3.2 correctly identifies the material type for the Sleeve, Item11, asType 304. 3. Reference (a) proposal exception #4 requests approval to perform testing inaccordance with VACCO Industries Acceptance Test Procedure ATP-V3D10064Revision A in lieu of MIL-V-24272 Amendment 1 dated 30 September 1968. In response, NAVSEALOGCEN comments that N00104-19-Q-FB99 Amendment0001, paragraph 3.3 provides for testing and acceptance requirements in accordancewith ATP-V3D10064. Testing for the subject solicitation is to be in accordance withATP-V3D10064 Revision A. The document references will be update to identifyRevision A of ATP-V3D10064. The tolerance provided for the inlet as listed inparagraph 3.3 of ATP-V3D10064 Revision A is to be 3375 psig +50 psig / -0 psig andthe tolerance provided for the outlet as listed in paragraph 3.4 of ATP-V3D10064Revision A is to be 155 psig +10 psig / -0 psig. NAVSEALOGCEN recommends thatfor the next revision of ATP-V3D10064, VACCO update the procedure to reflect aproof pressure tolerance of 50 psig for the inlet and a tolerance of 10 psig for the outlet. Modify paragraph 2.3.2 of the this solicitation to invoke VACCO Industries Acceptance Test Procedure ATP-V3D10064Revision A. amendment issued for TDP change. 1. DD1423 Data Item A001 may be waived if already on file at NAVSUP WSS Mechanicsburg. 2. 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 copiesare 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. 3. Submission of all certifications DD1423 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 180 days after contract effective date. 4. Small business set-aside has been dissolved; only one known supply source. 5. This requirement is a high priority unfilled customer order. \ 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 The documents and drawings listed below under DRAWING NO. are not provided with this Contract/Purchase order.
