This part of IEC 60493<\/span> <\/span> clarifies how a statistical analysis can be done with a small number of samples.<\/p>\n

This document will be useful when the accelerated test method is difficult to carry out, for example in cases where the dimensions of test specimens (including test devices) are very large in scale or the cost of test specimens is high. Testing is facilitated by enabling users to reduce the number of test specimens.<\/p>\n
