Last previous edition approved in as D – 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. Do not use arbitrary acceleration factors exposure. 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.

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.

Combining values from the two systems may result in non-conformance with the standard. Note 1 — This practice is technically equivalent to ISO This standard is not included in any packages. It is recommended that at least three replicates of each material be exposed to allow for statistical evaluation of results. Do not report irradiance or radiant exposure unless 8.
