Mechanical Failure Rate Data for Low Demand Applications

The use of IEC 61508 and IEC 61511 has increased rapidly in the past several years. Along with the adoption of the standards has come an increase in the need for accurate reliability data for devices used in Safety Instrumented Systems (SIS), both electronic and...

Development of a Mechanical Component Failure Database

In this paper, we present a methodology to derive component failure rate and failure mode data for mechanical components used in automation systems based on warranty and field failure data as well as expert opinion. We describe a process for incorporating new...

Accurate Failure Metrics For Mechanical Instruments

Probabilistic calculations that are done to verify the integrity of a Safety Instrumented Function design require failure rate and failure mode data of all equipment including the mechanical devices. For many devices, such data is only available in industry databases...
