The purpose of your engine is to compress fuel and air and then ignite it, creating heat energy that then makes mechanical motion. If your engine can't compress the air and fuel properly, the engine ...

A compression test reveals the condition of your engine's valves, its valve seats, and piston rings and whether these parts are wearing evenly. Healthy engines should have compression over 100 psi per ...

Lithium-ion batteries are a kind of rechargeable battery that is charged or discharged through desorption or insertion of lithium ions (Li +) from or into the active material structure. In recent ...

Until the mid-1970s, compression testing of composite materials received relatively little attention. Up to that point it, had generally been assumed that the compressive stiffness was approximately ...

The Combined Loading Compression (CLC) test method was standardized by ASTM in 2001, as ASTM D6641 1. During the past 10 years it has become the most-used compression test method for composite ...

Scan technology is essential for testing the digital content of large-volume devices. By using scan, you can make the device itself responsible for some of the “test” chores, and you can shorten the ...

People tend to spend, on average, several hours a day sitting on couches, chairs, and car seats, as well as considerable time on mattresses every night. Polyurethane foam plays a major role in ...

The size of designs continues to grow and IC manufacturers are pushing for higher test quality, especially in mission-critical applications such as transportation and medicine. More advanced nodes ...
