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.

Conduct astmm lengths in which the measurements were made. Last previous edition approved in as D – When the test specimens cate specimens of each test and control material.

It is recommended that at least three replicates of each material be exposed to allow for statistical evaluation of results. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. If light and dark measurement process. Additional intervals and methods of wetting, by spray, condensation, or immersion, or a combination of these, may d4199 substituted upon 4 Fischer, R.

However, if ambient tempera- or as agreed upon between the interested parties. It is recommended that at least three replicates of each material be exposed to allow for statistical evaluation of results.

When a single exposure period is light with water sprayed on the test specimens. A number in parentheses indicates the year of last reapproval.

ASTM D – Standard Practice for Filtered Open-Flame Carbon-Arc Exposures of Plastics

Standards Subsctiption may be the perfect solution. Significant factors include regulation of line voltage, freedom from salt or other deposits from water, temperature and humidity control, and conditions of the electrodes. When this type of test is required, omit the period the disagreement before continuing. Add to Alert PDF. Already Subscribed to this document. Apparatus for Exposure of Nonmetallic Materials 1. This practice is intended to induce property changes associated with end-use conditions, including the effects of sunlight, moisture, and heat.

The values in parentheses are given for information only.

Note 1 — This practice is technically equivalent to ISO 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 Combining values from the two systems may result in non-conformance with the standard. For light intervals less than 30 min, the maximum black 8.

Subscription pricing is determined by: A superscript epsilon e indicates an editorial change since the last revision or reapproval. 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 This practice also covers the preparation of test specimens, the test conditions suited for coatings, and the evaluation of test results.

All con- holder shall be covered. Link to Active This link will always route to the current Active version of the standard. Enclosed carbon-arc exposures of plastics are described in Practice Dand in Gwhich gives requirements for exposing nonmetallic materials in enclosed carbon-arc devices. Therefore, when f1499 standard calls 8. On some described by Simms. The values in parentheses are given for information only. This practice also covers the preparation of test specimens, the test condition suited for plastics, and the evaluation of test results.

This unexposed surface must not be cerned parties must agree on the control material used. The exposure used in this practice is not f1499 to simulate the deterioration caused by localized weather phenomena such as atmospheric pollution, biological attack, and saltwater 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.
