Fibre optic interconnecting devices and passive components - Part 03-01: Reliability - Design of an acceptance test for fibre pistoning failure of connectors during temperature and humidity cycling: demarcation analysis

IEC/TR 62627-03-01:2011(E) gives an example of the design of an acceptance test for ferrule style connectors when the dominant failure mode is fibre pistoning. The example applies to connectors which use epoxies or other adhesive polymers to bond the fibre into a ferrule. It combines existing evidence, mechanistic hypotheses and the demarcation approximation to develop an accelerated environmental exposure sequence that can be used on a pass-only basis to help ensure reliable service. This technical report was developed to serve only as an example of how accelerated acceptance tests can be designed. It is not intended as a normative standard for any specific application.
