  • Artificial weathering is used to test plastic materials resistance with accelerated effect of sunlight by using gas-discharge lamp (e.g. xenon arc lamps), electric arc (carbon) or fluorescent lamps. The exposure used in this practice is not intended to simulate the deterioration caused by localized weather phenomena, such as, atmospheric pollution, biological attack, and saltwater exposure.
  • Test intended to evaluate plastics for use in heavily polluted outdoor environments.
