SAMPLE INSPECTION:
3.3.1
DESTRUCTIVE TESTING:
3.3.1.1 SELECT THREE (3) UNITS FROM LOT AND MEASURE TOTAL DCR EVERY 20ºC OVER THE
TEMPERATURE RANGE FROM -55ºC THROUGH +125ºC.
3.3.1.2 CALCULATE DCA BY FOR EACH MEASUREMENT, USING EQUATION 3.2.1.1
3.3.1.3 CALCULATE, USING LINEAR REGRESSION, THE SLOPE OF THE ATTENUATION VS.
TEMPERATURE CURVE.
3.3.1.4 CALCULATE TCA USING THE FOLLOWING FORMULA:
SLOPE
TCA =
ATTENUATION @ 25ºC
