Abstract The aim of this paper is to illustrate primarily the suitability and secondly the ability of both PHM and ‘two‐sample’ tests in answering problems in the reliability field. The findings stress the fact that ‘two‐sample’ tests should be preferred for comparison purposes and PHM for modelling the behaviour of the equipment in the presence of various factors.
