Methods of statistically analysing data from electronic component lifetests are discussed. Particular emphasis is given toanalysis techniques using the assumptions of constant hazard rate (Exponential distribution), the Weibull distributionand mixed Weibull distributions. The methods used for analysing Weibull data when the data itself is non-uniform dueto both removal of test samples during test and also the non-continuance of surveillance of components under test arediscussed. Attention is finally given to the effect of two or more failure mechanisms which can produce S-shapedpatterns when data is plotted on Weibull Graph paper
