Devices on high temperature stress shall be cooled to 55 °C or lower before removing the bias. Cooling under bias is not required for a given technology if verification data is provided by the manufacturer. The interruption of bias for up to one minute, for the purpose of moving the devices to cool-down positions separate from the chamber within which life testing was performed, shall not be considered removal of bias. All specified electrical measurements shall be completed prior to any reheating of the devices, except for interim measurements subject to restrictions of clause 6.
