Any business handling heat treating for aerospace customers is likely to face Nadcap audits. Manufacturers like Boeing and Airbus require Nadcap accreditation, so the vast supply chain of subcontractors handling aerospace products must meet and maintain Nadcap requirements.

The quality and safety of heat treatment products are imperative. Because of this, the National Aerospace and Defense Contractors Accreditation Program (Nadcap) has clear and stringent guidelines for accreditation, which can often be challenging to attain. In this blog, I outline the step-by-step process for suppliers to gain Nadcap approval.
Ensuring that a furnace can perform repeatable and accurate cycles is a cornerstone of AMS2750E pyrometry specifications as well as Nadcap and CQI-9 standards. The best way to measure and test any furnace is through a temperature uniformity survey (TUS).
When it comes to pyrometry and thermal processing, details are critical. Adhering to the exacting AMS2750E standard demands that each step of heat treating meets specific requirements for sensors, instrumentation, equipment, tests and other details.
Any confusion in terminology can cause missteps that lead to audit findings, and this is particularly true when it comes to temperature uniformity surveys as applied to AMS2750E.
