CONTAINED IN VOL. 06.01, 2018 Defines the selection of test conditions for accelerated exposure testing of coatings and related products in fluorescent UV and condensation devices conducted according to Practices G151 and G154.

1.1 This practice covers the selection of test conditions for accelerated exposure testing of coatings and related products in fluorescent UV and condensation devices conducted according to Practices G151 and G154. This practice also covers the preparation of test specimens, and the evaluation of test results. Table 1 describes commonly used test conditions.

Note 1—Previous versions of this practice referenced fluorescent UV devices described by Practice , which described very specific equipment designs. Practice has been withdrawn and replaced by Practice G151, which describes performance criteria for all exposure devices that use laboratory light sources, and by Practice G154, which gives requirements for exposing nonmetallic materials in fluorescent UV devices.

Note 2—ISO 11507:1997 also describes fluorescent UV-condensation exposures of paints and coatings.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.3 This standard does not purport to address all of the safety problems 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.

A The cycles described are not listed in any order indicating importance, and are not necessarily recommended for the applications listed. Additional exposure cycles are described in Practice G154.

B The irradiance set point given is typical for devices operated without irradiance control. Other irradiance levels may be used, but must be described in the report.

C Previous editions of Practice D4587 contained non-mandatory irradiance set points in Table 1 that were commonly used in the industry. The previous set points were 0.72 and 0.77 W/(m2 · nm) at 340 nm for UVA 340 lamps. The measurement data used to establish these set points was inaccurate, due to an error in calibration on the part of one manufacturer. It has been found that, for most users, the actual irradiance when running at the previous set points was 11 to 15 % higher than the indicated set point. The set points shown in this edition of D4587 do not change the actual irradiances that have been historically used by these users. However, for users of equipment made by another manufacturer, the irradiance control system did not have the measurement inaccuracies described above, so running at the new set points will represent a change in the actual irradiance of the test. If in doubt, users should consult the manufacturer of their device for clarification.

D Temperature is at equilibrium for either an uninsulated or insulated black panel, although the response of the insulated black panel might be slower than that for the uninsulated black panel. Refer to Practice G151 for more information about the construction and differences between uninsulated and insulated black panels.

E Typical uses do not imply that results from exposures of these materials according to the cycle described will correlate to those from actual use conditions.

F SAE J2020 describes the test used in many automotive specifications and requires use of a FS40 fluorescent UVB lamp.

G Historical convention has established this as a very commonly used test cycle. This cycle may not adequately simulate the effects of outdoor exposure.
