Hello all,
Does anyone know of a clear definition of steady state conditions when
conducting heating tests? I have checked a number of 60335 series part 2
standards and came up blank for a definition:-(
Any help will be apreciated
Kind regards
Jacob.

Temperature rise is always an exponential curve.
I've looked and looked for a means of predicting
steady-state temperature during the initial rise
of temperature from the cold state. It can't
be done.
Once the data is reasonably complete, one can
determine the constants for the curve.
