The relative humidity (RH) during portions of this test could be a factor in the resistance of the test item to temperature shock. Equipment with a high moisture content could be affected by freezing of the moisture. In most cases, the RH may be uncontrolled, but specific RH values may be required when RH must be taken into consideration. I-4 ~ 1-4.1 wure an-.

The test conditions as presented in this procedure are intended to be in general ‘agreementwith other extremes described in this ‘document’.The primary purpose in e.5tablishingthege levels is to provide realistic conditions for”the traverse between the two temperature extremes. Thus, the temperatures at which”the item is stabilized before’transfer must be the most realistic, or possibly the most extreme,’that would be encountered during the specific operation.
