A physical test is a qualitative or quantitative procedure that consists of determination of one or more characteristics of a given product, process or service according to a specified procedure. Often this is part of an experiment.
Physical testing might have a variety of purposes, such as:
Some physical testing is performance testing which covers a wide range of engineering or functional evaluations where a material, product, or system is not specified by detailed material or component specifications. Rather, emphasis is on the final measurable performance characteristics. Testing can be a qualitative or quantitative procedure. Many Acceptance testing protocols employ performance testing e.g. In the stress testing of a new design of chair.
