I have been looking around the internet for information on testing the reliability of a particular part of a product and I have become overwhelmed by the amount of information out there.

The scenario I have is that I would like to calculate a figure for the reliability of a particular part of a product. There are 40 of this particular product in the field and I can test a small sample, e.g. 4-6, to obtain test data to use in the calculation of a reliability figure for the 40.

This raises some questions:

Given the small number of fielded units I don't think I can use normal statistical analysis because the population is too small. If that is the case how do I work out what a "significant" number of tests is to be confident in the reliability figure for the whole population?

I realise that the whole area of reliability engineering is vast so perhaps there are some useful books and websites that you could point me in the direction of?

Kind Regards,
