Like so many things in manufacturing, product testing is not a one-type-fits-all-applications procedure. Among the more well-known types of testing that manufacturers regularly perform are leak, mechanical performance, material (such as tensile strength) and computer simulation modeling.
Accelerated life testing (ALT) is one of the lesser-known procedures, but it is no less important. This type of testing involves capturing product life data under accelerated stress conditions, which cause the unit to fail more quickly.
