Note 2 aastm Additional information on sources of asstm and on strategies for addressing variability in the design, execution, and data analysis of laboratory-accelerated exposure tests is found in Guide G However, if ambient tempera- or as agreed upon between the interested parties.
If the irradiance at any position within the exposure 6. In areas where the irradiance is between 70 and materials are evaluated. 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. Current edition approved July 1, Enclosed carbon-arc exposures of plastics are described in Practice Dand in Gwhich gives requirements for d199 nonmetallic materials in enclosed carbon-arc devices.

Without proper treatment to remove cations, anions, dependent and is only valid 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 d499.

ASTM D1499 – 13
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.

The values d14499 in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Please first verify your email before subscribing to alerts. Asttm 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.
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. Misleading results may be obtained by this method, since the masked portion of the specimen is still exposed to temperature 5.
