Load Testing is an engineering test process whereby the properties of an object, material or structure are investigated for the purposes of development and/or quality assurance and it is not uncommon for load testing to be a destructive process.

In the context of vibration isolation, an example of destructive load testing would be  to measure the compressive strength in MPa of a concrete pour sample, a necessary aspect of quality assurance in the building and civil construction industry.

An example of non-destructive load testing would be to measure the spring stiffness of a isolator coil spring in N/m to determine if the spring complies with a known stiffness specification.
