Impact resistance

In mechanics, an impact is a high force or shock applied over a short time period when two or more bodies collide.

Impact tests are used in studying the toughness of material.  A material's toughness is a factor in its ability to absorb energy during deformation.  Brittle materials have low toughness as a result of the small amount of deformation that they can endure.  The impact value of a material can also change with temperature.  Generally, at lower temperatures the impact energy of a material is decreased.

Minus 50°C
We test our luminaires with the aid of a pendulum of known mass and length that is dropped from a known height to impact a specimen.  The specimen is placed in a specialized chamber with temperatures down to -50°C.  The temperature in the chamber should be five degrees lower than the lowest ambient temperature (Ta value) specified by the manufacturer for the luminaire being tested.
