      6 Measurements  

      The measurements specified in the applicable life test specification shall be made initially, at the  end of each interim period, and at the conclusion of the life test. Interim and final measurements  may include high temperature testing. However, testing at elevated temperatures shall only be  performed after completion of specified room (and lower) temperature test measurements. After  interim testing, bias shall be applied to the parts before heat is applied to the chamber, or within  ten minutes of loading the final parts into a hot chamber. Electrical testing shall be completed as  soon as possible after removal of bias from devices and no longer than 96 hours for high  voltage devices (defined as > 10 volts) or 168 hours for all other devices. If the availability of  test equipment or other factors make meeting this requirement difficult, bias must be maintained  on the devices; this may be either at the stress temperature or room temperature and the bias  may be reduced to nominal voltage from any accelerated voltage in use for stress. . If the  devices have been removed from bias and the time window is exceeded, the stress must be  resumed for the duration specified in Table 1 prior to completion of the measurements. After an  interim measurement, the stress shall be continued from the point of interruption. The time  window and the high temperature testing restrictions of this clause need not be met if  verification data for a given technology is provided.

      意思是如果读点时间超过了168小时,那么继续应力的测试就要追加24小时,以此类推~
