White Paper: Field Failure Rates - The Good, The Bad, The Ugly
There are many benefits to a company when they have access to good field failure data. Most of the benefits are categorized as saving money. At the same time, most of the expenditure to get good failure data is already being spent. Given an incremental cost of improving data collection…

White Paper: 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 component information into the database as it becomes…
White Paper: Using Simulation to Characterize Common Cause
Fault tolerant systems have been designed for safety critical applications including the protection of potentially dangerous industrial processes. These systems are typically evaluated and certified to functional safety standards with IEC 61508 [1] by agencies like exida Certification or one of the TUV companies. Many factors are taken into account…
White Paper: Alarm Management and ISA-18 - a Journey, Not a Destination
Poor alarm management is one of the leading causes of unplanned downtime, contributing to over $20B in lost production every year, and of major industrial incidents such as the one in Texas City. Developing good alarm management practices is not a discrete activity, but more of a continuous process (i.e.,…

White Paper: 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 where only failure rates are presented. The failure mode information…
