Question

Which of the following is the most appropriate reason for selecting accelerated life testing for an expensive product to determine adherence to design requirements? The test time to provide adequate reliability assurance under normal operating conditions is too long The current sample size and the life distribution show wear-out is likely The error in the population due to part-to-part variation is too large The probability density function of the product follows either a lognormal or a Weibull distribution

Explanation / Answer

For selecting accelerated life testing for an expensive product to determine adherence to design requirments the test time to provide adequate reliability assurance under normal operating conditions is too long.

Reliability of the life testing of an expensive product is too long means accelerated life testing for an expensive product is most appropriate. Relibility is to long means life time of a accelerated life testing for an expensive product is better. Another options are not appropriate for selecting acceleretd life testing for an expensive product to determine adherence to design requirments as their impact doesnot matter for selecting accelerated life testing for an expensive product.
