Failure Rate Thermal and Electrical Stress Sample Clauses

Failure Rate Thermal and Electrical Stress. Derating Thermal and electrical stress influences on part failure rate will be incorporated into the reliability assessments as soon as the necessary design data are available and the stress analyses are completed. The final assessment of each design will incorporate failure rates derived from the calculated stress ratios and the operating temperature of the units or equipment. For those cases in which the operating temperature may change over life as a result of thermal degradation, the equipment operating temperature may be assumed to be one third of the maximum "predicted" temperature at the beginning of the mission and two thirds of the "predicted" temperature at the end of the mission (or equipment life). Equipment operating temperature = 1/3 * BOLMAX Tem + 2/3 EOLMAX Temp USE OR DISCLOSURE OF THE DATA CONTAINED ON THIS SHEET IS SUBJECT TO THE RESTRICTION ON THE TITLE PAGE. Table 2-3.
