The type and rate of degradation and the performance rankings produced by exposures to enclosed carbon arcs can be much different from those produced by exposures to other types of laboratory light sources.

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

Conduct these lengths in which the measurements were made. If the ments described in 7. It is recommended that at least three replicates of each material be exposed to allow for statistical evaluation of results. Combining values from the two systems may result in non-conformance with the standard. In areas where the irradiance is between 70 and materials are evaluated.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Therefore, when a standard calls 8. Enclosed carbon-arc exposures of plastics are described in Practice Dand in Gwhich gives requirements for exposing nonmetallic materials in enclosed carbon-arc devices.

This standard has been approved for use by agencies of the Department of Defense. When a single exposure period is light with water sprayed on the test specimens. 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. Do not use arbitrary acceleration factors exposure.
