This document is an amendment to Solicitation Number N6893626Q50070001, issued by the Naval Air Warfare Center, Weapons Division. The primary purpose of this amendment is to clarify the Statement of Work (SOW) regarding on-site calibration services for laboratory equipment and to extend the solicitation response date. The SOW now specifies that most calibration services must be performed in place at the Materials Engineering Branch Laboratory in China Lake, CA, with exceptions for items like weights, gage blocks, hygrometers, and ring gages, which may be calibrated off-site with prior approval. The amendment also changes the response due time from 2:00 PM to 10:00 AM and extends the response due date from October 17, 2025, to October 23, 2025. Contractors must acknowledge receipt of this amendment for their offers to be considered.

The "China Lake Calibration List 2025" document is a detailed inventory of various calibrated equipment, likely for a government facility involved in federal operations. The list includes a wide array of tools such as digital and dial calipers, micrometers, thread plug gages, ring gages, digital and dial indicators, torque wrenches, thermocouple temperature gages, scales, force gages, environmental chambers, ovens, salt-fog chambers, digital multimeters, and a hardness tester. Each entry specifies the manufacturer/model number, serial number, description, size or range, tolerance, and room number where the equipment is located. The document also includes notes indicating requirements for actual values traceable to NIST and specific temperature/humidity tolerances. This comprehensive list is crucial for maintaining precision and accuracy in various technical operations, ensuring compliance with calibration standards for sensitive government work.

This document clarifies calibration requirements for environmental and salt-fog chambers. For the AES HD-508 Environmental Chamber, calibration at 160°F and 95% RH is confirmed, with nine internal temperature sensor locations. The digital units for recorder and humidity gauge should be checked against actual chamber values. For the Singleton SCCH Custom_54211 Salt-Fog Chambers, a "Report of Actual" calibration is acceptable, documenting actual measured values traceable to NIST for temperature, %RH, and pressure gauges. Salinity measurements are not required as they are tracked separately. This outlines the specific calibration procedures for these assets, ensuring compliance and accurate reporting.

This government solicitation, N6893626Q5007, from the Naval Air Warfare Center Weapons Division, outlines a request for proposals for Women-Owned Small Businesses (WOSB) to provide on-site equipment calibration services for the Materials Engineering Branch in China Lake, CA. The contract will cover a base year and two option years, with all calibration activities requiring ISO-17025 accreditation and primarily performed on-site. Specific equipment may be calibrated off-site with prior approval. Key requirements include providing personnel information for badge requests, adherence to a 4/5/9 work schedule, and utilization of the Wide Area WorkFlow (WAWF) system for invoicing and payment. The document details administrative information, delivery schedules, inspection and acceptance procedures, and a comprehensive list of applicable FAR and DFARS clauses, emphasizing compliance with various federal regulations and certifications for commercial products and services.

The Naval Air Warfare Center, Weapons Division at China Lake, CA, is seeking a supplier to calibrate laboratory equipment for its Materials Engineering Branch. The contract will span a base year and two option years, requiring all calibration to adhere to ISO-17025 standards and be performed by an ISO-17025 accredited supplier. Most calibrations will occur on-site in Building 02466, Rooms 2000-2019, with an expected on-site duration not exceeding two business days. Certain items, including weights, gage blocks, hygrometers, and ring gages, may be calibrated off-site, with all off-site items to be returned within one week. The supplier must provide personnel information for badge requests 30 days prior to on-site work and supply documentation, including calibration stickers and certificates, within two weeks of completion. Certificates can be hard copies or electronic.
