(Practice)Standard Practice for Filtered Open-Flame Carbon-Arc Exposures of Paint and Related Coatings
Standard Practice for Filtered Open-Flame Carbon-Arc Exposures of Paint and Related Coatings
SIGNIFICANCE AND USE
4.1 The ability of a paint or coating to resist deterioration of its physical and optical properties caused by exposure to light, heat, and water can be very significant for many applications. This practice is intended to induce property changes associated with end-use conditions, including the effects of sunlight, moisture, and heat. 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.
4.2 Cautions—Variation in results may be expected when different operating conditions are used. 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. Refer to Practice G151 for detailed information on the caveats applicable to use of results obtained according to this practice.Note 1—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 G141.
4.2.1 The spectral power distribution of light from an open-flame carbon-arc is significantly different from that produced in light and water exposure devices using other carbon-arc configurations or other light sources. 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.
4.2.2 Interlaboratory comparisons are valid only when all laboratories use the same type of carbon-arc, filters, and exposure conditions.
4.3 Reproducibility of test results between laboratories has been shown to be good when the stability of materials is evaluated in terms of performance ranking compared to other materials or to a control.4,5 Therefore, exposure of a similar material of known per...
SCOPE
1.1 This practice covers the selection of test conditions for accelerated exposure testing of coatings and related products in filtered open-flame carbon-arc devices conducted according to Practices G151 and G152. This practice also covers the preparation of test specimens, the test conditions suited for coatings, and the evaluation of test results. Table 1 describes commonly used test conditions.
1.2 This practice does not cover enclosed carbon-arc exposures of paints and related coatings, which is described in Practice D5031/D5031M. Another procedure for exposing these products is covered by Practice D3361/D3361M, in which the specimens are subjected to radiation from an unfiltered open-flame carbon arc that produces shorter wavelengths and higher levels of short wavelength radiation than filtered open-flame or enclosed carbon arcs.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

NOTE 1—Previous versions of this practice referenced carbon-arc devices described by Practice G23, which described very specific equipment designs.
Practice G23 has been withdrawn and replaced by Practice G151, which describes performance criteria for all exposure devices that use laboratory light
sources, and by Practice G152, which gives requirements for exposing nonmetallic materials in filtered open flame carbon-arc devices.
1.2 This practice does not cover enclosed carbon-arc exposures of paints and related coatings, which is described in Practice
D5031D5031/D5031M. Another procedure for exposing these products is covered by Practice D3361D3361/D3361M, in which
