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.
