Sequential compliance test method for lognormal distribution

Using the experience of sequential verification test program in exponential distribution for reference, the method of making the sequential verification test program in lognormal distribution was discussed, which takes the average life as an indicator. The test procedure of sequential test was provided, and the upper limit value of the producer and consumer risks were studied under censoring. According to the sampling method in practical engineering, the simulation method was proposed to evaluate the above mentioned test program. Evaluation results indicate that the proposed sequential verification test program can meet the requirements of controlling both sides of risk on the premise of satisfying the requirement of sample and censored size. And the consumer’s risk is lower than the expected value.
