The applied methods are subject, among others, to the following aviation standards:
- ARP 4761, ARP 4754A, MIL-STD-882E, MIL-STD-1629A
- NPRD-11, EPRD-97, MIL-HDBK-217F, NSWC-06, FMD-97
- NUREG-0492
For equipment not related to aviation, the following standards are currently applied:
- EN 61508, EN 62061, EN 50126
Random
Failure Behavior
The failure of a system is considered random if its probability of occurrence is subject to statistical laws. In the probabilistic approach, the random failure forms the basis of the functional failure states. It is the foundation for functional safety and reliability analysis. To determine the risks or safety integrity levels associated with the functional failure states of a system, AEMS International GmbH offers the following methods:
- Functional Hazard Analysis
(engl. FHA: Functional Hazard Analysis) - Component-based Reliability Analysis
(engl. ERP: Equipment Reliability Prediction) - Failure Modes and Effects Analysis
(engl. FMEA: Failure Modes & Effects Analysis) - Failure Modes, Effects and Criticality Analysis
(engl. FMECA: Failure Modes, Effects & Criticality Analysis) - Failure Modes and Effects Summary
(engl. FMES: Failure Modes & Effects Summary)
