Hi Jean Paul,

From what I have seen each major manufacturer in the 50s 60s the Mil, Auto
and probably more all had different temperatures. IBM, MartinMarietta, GE,
Ford, Bell Labs etc.

Some of the temperatures were set based on the specific reliability groups
and materials used or their specific application environments. Even within
the same industries different temperatures would be used by different
companies.
