Refer to Practice G for detailed information on the caveats applicable to use of results obtained in accordance with this practice. Note 1—Previous versions of this practice referenced xenon-arc devices described in Practice G 26which described very specific equipment designs.

Practice G 26 is being replaced by Practice Gwhich describes performance criteria for all exposure devices that use laboratory light sources and by Practice Gwhich gives requirements for exposing nonmetallic materials in xenon-arc devices. The exposure used in this practice is wstm intended to simulate the deterioration caused by localized weather phenomena, such as, atmospheric pollution, biological attack, and saltwater exposure.
It is recommended that at least three replicates of each material be exposed to allow for statistical evaluation of results.

Historical Version s – view previous versions of standard.
This practice is intended atm induce property changes associated with end-use conditions, including the effects of daylight, moisture, and heat. Significant factors include regulation of line voltage, freedom from salts or other deposits from water, temperature and humidity control, and condition and age of the lamp and filters.
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 aetm Guide G This practice also f2565 the preparation of test specimens, x2565 test conditions best suited for plastics, and the evaluation of test results. This practice also covers the preparation of test specimens, the test conditions best suited for plastics, and the evaluation of test results.
Note 2—This practice is technically equivalent to ISO Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It is preferable that the number of specimens of the control material be the same as that used for test materials. X2565, all references to the use of this practice must be accompanied by a report prepared in accordance with Section 9 that describes the specific operating conditions used.
This practice and ISO address the same subject matter, but differ in technical content. Practice G 26 will be balloted for withdrawal before December
