This part of IEC 62343, which is a technical report, describes failure mode effect analysis (FMEA) for optical units of dynamic modules. FMEA is one of the effective and useful analysis methods to determine the reliability evaluation test items and conditions which are defined in future reliability qualification documents. In order to estimate the lifetime for a module, there is a typical procedure. The first step is to identify the dominant failure modes. The second step is to determine the acceleration tests according to these failure modes. The third step is to carry out the test. The fourth step is to estimate the acceleration factors. Finally, the fifth step is to calculate the lifetime of the dynamic module. The IEC 61300-2 series defines environment and mechanical tests. This technical report describes the dominant failure mode for dynamic modules and relevant tests from the IEC 61300-2 series.
