In aerospace, precision in thermal processing is non-negotiable. AMS2750E mandates rigorous calibration protocols for heat treatment equipment, ensuring compliance with SAE International and Nadcap audits11.
Critical Requirements:
System Accuracy Tests (SAT): Validate the entire measurement loop (sensors, instruments, wiring) using traceable field test instruments11.
Temperature Uniformity Surveys (TUS): Map furnace zones to ±3°C accuracy, with reports detailing sensor placement and corrections11.
Calibration Hierarchy: Secondary standards (e.g., Beamex MC6 calibrators) must meet 0.5°C accuracy for thermocouples11.
Case Study: A UK aerospace supplier reduced calibration errors by 30% using AMS2750E-compliant workflows11.
