There is some confusion about the various tests available to the vibration testing engineer. Difficulties encountered usually center on the differences between sinusoidal vibration (sine testing) and random vibration testing.doi:10.1109...
Durability testing involves a range of tests that simulate real-world conditions and scenarios. The choice of tests is driven by the nature of the product as well as the industry for which it is intended. Here are the major types of durability tests that are employed: Vibration testing Product...
As he said in his book, The Healing Power of Sound:“If we accept that sound is vibration and we know that vibration touches every part of our physical being, then we understand that sound is heard not only through our ears but through every cell in our bodies.”...
with a consequential increase in both non-destructive testing (NDT) and manual inspection that is expensive and disruptive to efficient rolling stock maintenance. TWI plays a key role in an InnovateUK project, aiming to use complimentary methods of high frequency vibration and Acoustic Emission (AE...
What is Hast chamber? HAST (Highly Accelerated Stress Test) chambers reduce the time it takes to complete humidity testing for semiconductors. By elevating temperatures above 100°C and increasing the pressure, simulation of normal humidity tests can be made while maintaining the same failure mechanis...
The candidates for proactive maintenance include components that wear and those that fail. What kind of equipment is prone to failing? Consider running a vibration or thermography analysis to test the stress points. Define the maintenance intervals using the wear level, predicted failure, time, and...
HIPOT test is applied after tests such as fault condition, humidity, and vibration to determine whether any degradation has taken place. Other examples include identifying a pinhole defect in insulation or finding an enlarged solder footprint. As per IEC 60950, The Basic test Voltage for Hipot ...

NDT stands for non-destructive testing and is also known as non-destructive examination (NDE), non-destructive inspection (NDI) and non-destructive evaluation (NDE).Non-destructive testing (NDT) is a testing and analysis technique used by industry to evaluate the properties of a material, ...
Today, test benches perform objective testing in a controlled environment. Tests can be repeated hundreds or thousands of times, and the results can be compared objectively across numerous testing cycles. When products are intended for human use, a good approach is to use objective, repetitive ...
