Hi All Can any one please clarify me In autoclave validation of heat distribution study how the difference between Maximum and Minimum temperatures of thermocouples are set and on which criteria it is been set and what and where the impact is observed if the difference is varied. For example in autoclave heat distribution study the acceptance is given as; The difference between Maximum and Minimum temperatures of all the individual thermocouples during steady state shall be within +/- 1.0 oC & The difference between Maximum and minimum temperature among all the thermocouples during steady state shall be with in +/-2.0 oC Now if the difference between maximum and Minimum temperatures of all the individual thermocouples during steady state is more or less than i.e, (+/-1.0 oC) & The difference between maximum and minimum temperature among all the thermocouples during steady state is more or less than (+/-2.0 oC) then where the impact is observed and how the acceptance criteria is set.
