Pyrometry - AMS 2750F vs. Nadcap

Jun 22, 2021 2:23:34 PM / by Jason Schulze posted in Nadcap, thermal processing, Pyrometry, ams2750f, Aerospace

0 Comments

Abstract

AMS2750F and Nadcap requirements (both checklists and the pyrometry reference guide) amount to 70% of all Nadcap Heat Treat Audit findings. This trend has been consistent for over a decade now. This can be attributed to a lack of comprehension of the specification, internal execution and inadequate internal auditing systems at the supplier level as well as the prime level. Conrad Kacsik is committed to improving the comprehension of AMS2750F within the industry. We believe that this is the first step in creating a successful Pyrometry Compliance System for our customers.

When AMS2750 went from revision D to revision E, one of the changes was that ASTM E29 was required for rounding significant digits. Rounding using ASTM E29 is not your old spreadsheet version of rounding—more discretion is required.

Understanding AMS2750E & Nadcap Checklist Requirements

May 2, 2019 4:27:00 PM / by Jason Schulze

0 Comments

Pyrometry procedures that comply with AMS2750E and/or Nadcap requirements can be complex and challenging to meet. I often perform gap analyses on heat-treat processes and uncover issues with procedures and work instructions that, if not remedied, will ensure failure when it comes to meeting Nadcap or AMS2750E requirements.
