Hot, Humid then Extreme Heat, Moderate RH transition rates
When we use the following conditioning (ISTA 2A);
Hot, Humid then Extreme Heat, Moderate RH:
72 then 6hrs, 38°C (100°F) then 60°C (140°F) 85% RH ±5% then 30% RH ±5%
Is there an transition rate for the temperature and humidity described or can we us any rate we want?.
Second question is, does the 6 hours start when the 60°C and 30% Humidity is reached or does the time start when the transition starts?
The temperature and humidty conditioning times specified in the Procedures are dwell times at the specified conditions, and do not include any time which may be required to transition from one set of conditions to another. Some procedures specify ramp times. In those cases the ramp times should be followed.
