This is a Statement of Work for calibration and certification services for NASA Langley's two ABAR vacuum furnaces manufactured by Ipsen (ABAR II: ECN #418688, serial #8558 from 1973; ABAR III: ECN #418696, serial #10866 from 1981).

The contractor must perform periodic calibration and certification of the vacuum system, temperature instrumentation, and inputs to maintain qualified certification for both furnaces in accordance with industry standard AMS 2750H. Key service requirements include: calibrating furnace instrumentation (controller and control thermocouples), vacuum gages, and performing system accuracy testing to verify thermocouple and vacuum gage measurement accuracy. All calibrations must use up-to-date National Institute of Standards and Technology (NIST) traceable equipment and reference standards, with NIST-traceable equipment required for on-site calibrations at NASA Langley. The contractor must perform temperature uniformity surveys (TUS) using NASA-provided structure and thermocouples; after four successive quarterly furnace TUS tests pass, the frequency of periodic temperature uniformity surveys may be reduced per AMS 2750H. Scheduled surveys must maintain certification continuity with ABAR II requiring quarterly surveys on 3/25/2026, 6/24/2026, and 9/24/2026 (subsequent quarters due December 2026, March 2027, and September 2027), and ABAR III requiring quarterly surveys on 6/24/2026 and 9/24/2026 (subsequent quarters due December 2026, March 2027, and September 2027). Additional deliverables include affixing an initialed and dated calibration sticker to each furnace post-calibration and providing documentation and data from each calibration and certification visit. The contractor must travel to NASA Langley Research Center in Hampton, Virginia to perform all work on-site and obtain a valid badge to access the facility.
