Without proper treatment to remove cations, anions, dependent and is only astmm if it is based on data from a organics, and particularly silica, exposed panels will develop sufficient number of separate exterior and laboratory- spots or stains that may not occur in exterior exposures. Table 1 describes commonly used test conditions.

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. Your Alert Profile lists the documents that will be monitored.

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 values in parentheses are given for information only. 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.

Significant factors include regulation of line voltage, freedom from salt or aetm deposits from water, temperature and humidity control, and conditions of the electrodes.

You may delete a document from your Alert Profile at any time. We have no amendments or corrections for this standard. Refer to Practice G for detailed information on the caveats applicable to use of results obtained in accordance with this practice. This standard is not included in any packages. 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 Standards Subsctiption may be the perfect solution.

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. Therefore, no reference to the use of this practice shall be made unless accompanied by a report prepared according to Section 10 that describes the specific operating conditions used. 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 dd1499 described in Practice D, and in G, which gives requirements for exposing nonmetallic materials in enclosed carbon-arc devices. Additional intervals and methods of wetting, by spray, condensation, or immersion, or a combination of these, may be substituted upon 4 Fischer, R.

Significant factors include regulation of line voltage, freedom from salt or other deposits from water, temperature and humidity control, and conditions of the electrodes.
