The ISO 13381-1 standard´s failure prognostics process through an example

Industrial failure prognostics can be considered as the key process of any condition-based maintenance solution. However, contrary to fault diagnostics which is a mature research and industrial work, failure prognostics is a new field for which few applications exist. In the last decade, the interest for this activity has led to some open and industrial standards where the main objective is to provide users with a guidelines allowing them to perform failure prognostics for a large class of industrial systems. However, these standards, rightly, do not emphasize on any particular example to illustrate their content. The present paper aims at explaining the process of failure prognostics, presented in the standard ISO 13381-1, through an electromechanical example. The purpose is to help beginner researchers in the field of industrial failure prognostics to assimilate the main tasks of the process proposed by the standard. The prognostics process is chosen because it represents the key task among the rest of topics proposed and published by the standard. Thus, the comprehension of this part is important to develop prognostics methods and algorithms based on the solid recommendations given by the international organization for standardization.
