This document is a Contract Data Requirements List (CDRL) detailing specific data items required for Contract Line Item Number (CLIN) 0002, related to the "UNIVERSAL SLIP RING" system. It outlines the types of documentation and certifications the contractor must provide.

• Data Items: The CDRL specifies four data items (A001 through A004):
  • A001: Certificate of Compliance
  • A002: Mercury Free Certification
  • A003: Certificate of Analysis
  • A004: Technical Report - Study/Services (Process Certification)
• Submission: Most items are required "1 TIME" upon completion of each delivered batch, with a "Final" submission. Specific submission dates are to be determined or are dependent on other blocks.
• Distribution Statement D: All data items are subject to Distribution Statement D, meaning distribution is authorized to U.S. Government Agencies and their contractors (Critical Technology). Other requests must be referred to the Naval Undersea Warfare Center (NUWC), Newport Division.
• Export Control: An "EXPORT CONTROL WARNING NOTICE" is included, indicating that the technical data is restricted by U.S. export control laws and requires dissemination in accordance with DoD Directive 5230.25.

This CDRL is crucial for bidders as it defines the specific documentation and certifications required as part of the contract. Understanding these requirements, including submission timelines and distribution limitations, is essential for accurate proposal development and contract fulfillment. Bidders must ensure they can meet these data delivery requirements, particularly those related to compliance, certifications, and technical reporting, and adhere to the strict export control and distribution guidelines.

This document, "Material Specification SAE AMS2700F," details the requirements for the passivation of corrosion-resistant steel parts. It outlines the processes, methods, types, and classes for passivation, as well as the associated testing and quality assurance provisions.

• Methods: Specifies two primary methods: Passivation in Nitric Acid (Method 1) and Passivation in Citric Acid (Method 2).
• Types (Method 1): Details eight types of nitric acid passivation, varying in temperature, concentration, and additives like sodium dichromate.
• Classes: Defines four classes for passivation verification testing (Class 1, 2, 3, 4), each with different testing frequencies and requirements for corrosion resistance and surface appearance.
• Requirements: Covers procedure, post-treatment, properties (corrosion resistance, humidity, water immersion, copper sulfate test, salt spray, surface appearance), and written procedures.
• Quality Assurance: Outlines responsibility for inspection, classification of tests (acceptance and periodic), preproduction tests, sampling plans, and approval processes.
• Applicable Documents: Lists relevant SAE and ASTM publications.

Vendors providing passivation services must adhere to this specification. It defines the technical requirements, testing protocols, and quality standards that must be met. Understanding these details is crucial for accurate bidding, process implementation, and successful contract execution. The specification also provides guidance on recommended passivation solutions for various steel alloys.

Standard Specification

This document, ASTM A967/A967M-25, establishes a standard specification for chemical passivation treatments for stainless steel parts. It aims to improve the corrosion resistance of stainless steel by removing contaminant iron and other exogenous matter, thereby facilitating the formation of a protective passive metal oxide film. It provides alternative treatments and testing methods to confirm the effectiveness of passivation.

• Passivation Treatments: Specifies various treatments using nitric acid (Section 6), citric acid (Section 7), and other chemical or electrochemical solutions (Section 8).

• Preparation: Outlines requirements for descaling, cleaning, and pickling prior to passivation (Section 5.3).

• Rinsing and Neutralization: Details procedures for rinsing and neutralization to stop chemical reactions (Section 9).

• Post-Cleaning Treatments: Includes optional treatments to accelerate passive film formation (Section 10).

• Finish: Passivated parts must exhibit a chemically clean surface without etching, pitting, or frosting (Section 11).

• This standard is intended as an alternative to Federal Specification QQ-P-35C.

• Purchasers may specify additional requirements, including specific treatments, test practices, lot sizes, and documentation (Section 4).

• Verification Tests: Details several practices (A through G) for testing the effectiveness of passivation, primarily focusing on the detection of contaminant iron (Section 14).

• Lot Definition & Frequency: Defines how lots are determined and specifies testing frequency (Section 13).

• Rejection: Outlines criteria for lot rejection and retesting (Section 15).

Not applicable to this document.

• The standard includes appendices with historical information and guidance on selecting treatments for different stainless steel grades (Appendix X1 and X2).
• It is the user's responsibility to establish appropriate safety, health, and environmental practices (Section 1.6).

• Domestically Sourced Material: Not Required.
• Product Identification: Required on external surfaces of items/packages. Parts must be returned with associated tags.
• Process Certification: Required, for items manufactured according to special processes identified.
• Special Packaging Requirements: Required to protect parts during handling and transportation.
• GFI: Documentation Provided: Lists specific documentation required, including ASTM A967-A967M-25, SAE AMS2700F, and RIR_QAP_W05385.
• Enclosure Note 1: Specifies passivation requirements (IAW QQ-P-35, SAE AMS2700, ASTM A967/A967M) and IAW Drawing Tabulation Block. It also lists CDRLs: A001 Certificate of Compliance, A002 Mercury Free Statement, A003 Certificate of Analysis, and A004 Process Certification.

This report outlines the mandatory quality documentation and certifications required for the "USR CHECK VALVE" part. Vendors must ensure they can provide all specified documentation and meet the material and process requirements to successfully fulfill this order. Failure to provide required documentation may result in rejection.
