Equipment Failure Definition: A Prerequisite for Reliability Test and Validation

July 6, 2011 | Leave a Comment

Abstract While product reliability has become a major concern to most organizations, many have overlook developing good reliability specifications. This oversight can result in ambiguous and purposeless reliability testing during the validation phase of the product development. Effective reliability testing requires well-defined reliability specification. After all, the prime objective of a reliability engineering program is [...]

Overall Reliability Education

May 16, 2011 | Leave a Comment

One objective of working in reliability is to minimize Life Cycle Costs (LCC). In order to do this a Reliability Engineer must select which reliability tools will need to be used and then utilize them properly for the product life cycle. As well he needs to be on top of the information that is generated [...]

What is HALT and what is not HALT?

October 4, 2010 | Leave a Comment

When we think of HALT, we think of HALT Chambers and the stresses they provide – cold temperature, hot temperature, rapid thermal transitions, vibration stress, and combined thermal and vibration environments. We need to expand our thinking of HALT into meaning any stress that can accelerate finding defects (in other words, to find design weaknesses [...]

Chi Squared Distribution for RDT

July 23, 2009 | Leave a Comment

Chi Squared Distribution for Reliability Demonstration Testing When planning a Reliability Demonstration Test (RDT), your objective is to demonstrate a certain reliability (or MTBF) at a certain Confidence Level (CL). If you want to determine what MTBF at a particular CL you have demonstrated, if you tested T number of hours, you would use the [...]
