White Paper: Field Failure Data Analysis – Extreme Data Filtering
This paper describes a bad field failure data analysis practice where many field failures are ignored or discarded (filtered) before the failure rate calculation is done. This has been called “extreme data filtering.” Several examples are given. A failure rate resulting from this filtering process will be significantly lower than…
White Paper: Analysis of a Ball Valve / ERC Assembly
This paper details a method for determining the safety integrity level (SIL) of a Ball Valve/Emergency Release Coupling (BV/ERC) assembly. It examines how the design and arrangement of these components affect their reliability and the likelihood of dangerous failures. The study also shows how minimizing accidental “trips” of the system…
Blog Entry: A Component Reliability Data Source Must Include Useful Life
In exida’s Component Reliability Database (CRD) , every component includes a Useful Life expressed in years and/or cycles. Understanding Useful Life This post, drawing from exida's whitepaper [1] on how environmental factors impact component reliability, shows how Useful Life, like failure rates, is affected by factors such as temperature and…
Training Course: Functional Safety Engineering for Complex Machines
With the limitations in the IEC 62061 and ISO 13849 machine safety standards, there is a need to combine elements of those standards along with the overall IEC 61508 standard to best manage functional safety for complex machines such as in mining and materials handling applications. Machine functional safety is…
Blog Entry: Stress vs. Strength: The Foundation of Component Reliability in FMEDA
The So What: Your product's safety and reliability depend on the constant battle between component stress and strength throughout its useful lifetime. This dynamic is influenced by everything from design and manufacturing to usage and environment. Crucially, without accurately factoring in real-world stress and strength, your reliability predictions will be…
Recorded Webinars: Show Your Strength: Leveraging FMEDA to Highlight Design Excellence
An FMEDA done with a complete component database will allow designers to take credit for good design. Design decisions including EMC/surge protection, de-rating of component parameters, heat sinks, PC board coating, physical protection, surface finish on moving parts, etc. will reduce the component failure rates and often increase Useful Life. This webinar will explain the fundamental stress-strength concepts and give examples of the exida Component Reliability Database (CRD) and how the failure rates change when design strength choices are made.
