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

Therefore, no reference to the use of this practice shall be made unless accompanied by a report prepared in accordance with Section 9 that describes the specific operating conditions used. Refer to Practice G for detailed information on the caveats applicable to use of results obtained in accordance with this practice. Note 2—Additional information on sources of variability and on strategies for addressing variability in the design, execution, and data analysis of laboratory-accelerated exposure tests is found in Guide G 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.

It is recommended that at least three replicates of each material be exposed to allow for statistical evaluation of results. Significant factors include regulation of line voltage, freedom from salt or other deposits from water, temperature and humidity control, and conditions of the electrodes. Scope 1. This practice also covers the preparation of test specimens, the test condition suited for plastics, and the evaluation of test results. Enclosed carbon-arc exposures of plastics are described in Practice D , and in G , which gives requirements for exposing nonmetallic materials in enclosed carbon-arc devices.

The values in parentheses are given for information only. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
