I first encountered the Nadca 207 specification in 1999. At that time, a large die weighing 400 kg, hardened by our heat treatment plant, cracked in the die casting foundry, and the tool shop wanted to compensate us for the damage caused. We did not believe that the fault was on our side. But then we learned about the Nadca 207 specification, and because we had good contacts, we invited Mr. Corwyn Berger, one of the co-authors of the specification, to a lecture in the Czech Republic. His presentation "Extended tool life on die casting" permanently changed our views and the way we work in the heat treatment shop.

What are the requirements for a radiation survey according to AMS 2750F (Aerospace Material Specifications)?

First of all, it is important to state that such a survey is required under AMS 2750, exclusively for furnaces used for the Thermal Treatment of Aluminium Alloys and it is limited to process temperatures above 427°C.

Therefore, it is mainly for plants dedicated to Thermal Treatment of Solubilisation. The solubilisation temperature for many alloys is very close to the eutectic melting point and this is why in these types of furnaces, it is also necessary to test the radiation effect directly on the metal as well as measuring and certifying the temperature uniformity of the operating volume qualified within the limits required by the applicable specifications.
