Failure Analysis
The analysis of failures is very important for revealing the cause of a particular failure, for taking appropriate measures to avoid similar failures in the future, and for improving similar…
Introduction to diagnostics
The reliability of many objects, machines, transport means, various appliances, or processes can be increased and operational costs can be reduced by the application of diagnostics. This is a branch…
maintenance
The operational reliability and service life of machines, vehicles, various appliances, bridges, and many other long-life objects are strongly influenced by maintenance. This term generally denotes small works for restoring full…
Time to Failure of Deteriorating Objects
As we have seen in Chapter 4, failure rate often changes with time (Fig. 1 there). This is because the main causes of failures change with time. The early failures (stage…
Reliability of Systems
Many objects consist of more parts or elements. From reliability point of view, an element is any component or object that is considered in the investigated case as a whole and…
Bathtub Curve
Failure rate, can change with time. Figure 1 shows the time course of λ(t) typical of nonrepairable objects, such as electrical bulbs, pumps, switches, or springs, and also living beings, including humans.…
Characteristics of Reliability
Reliability is usually characterized by the probability of failure or by the time to failure. If failure is considered as a single event (e.g. collapse of a bridge), regardless of…
probability basics
The occurrence of failures is usually accompanied by some uncertainty. This is due to many factors that we cannot control, and call them therefore random. Similarly, we speak about random events, which…
Basic Terms of Reliability
In matters of reliability, people from various branches — manufacturers, customers, technicians, and lawyers — must often communicate together, especially when trying to find the answers to the following questions:…
Cargo Surveys
IMS offers a full range of commercial survey, inspection, sampling and testing services with supporting Certificates and other relevant documentation, including, but not limited to, the following: Hold and Tank…
