The type and rate of degradation and the performance rankings produced by exposures to filtered open-flame carbon-arcs can be much different from those produced by exposures to other types of laboratory light sources. Significant factors include regulation of line voltage, freedom from salt or other deposits from water, temperature and humidity control, and conditions of the electrodes.

Last previous edition approved in as D – It is recommended Instrumental measurements are recommended whenever possible. Enclosed carbon-arc exposures of plastics are described in Practice Dand in Gwhich gives requirements for exposing nonmetallic materials in enclosed carbon-arc devices.

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. This practice is intended to induce property changes associated with end-use conditions, including the effects of sunlight, moisture, and heat.
