Our glass reinforced polyester laminate is tested in a controlled laboratory with a simulation of accelerated weather with an exposure cycle of 8 hours UV followed by 4 hours condensation continuously. Send us a request Wilton UK: NOTE 3—Additional information on sources of variability and on strategies for addressing variability in the design, execution and data analysis of laboratory accelerated exposure asttm is found in Guide G 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.
This method is preferred over evaluating materials after an arbitrary exposure time or radiant exposure.
ASTM D – UV EXPOSURE OF PLATINGS
Last previous edition approved in as D — 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.
Consider product use requirements when selecting appropriate methods. These cycles would be continued for extended periods of time – up to thousands of hours – simulating even longer periods of time in the real world. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Table 1 describes commonly used test conditions. Measure ambient temperature at a maximum distance of mm 6 in. Assurance Testing Inspection Certification.
The values given in parentheses are for information only.
NOTE 11—Fischer illustrates use of rank comparison between test and control materials in speci? Additional exposure cycles are described in Practice G NOTE 10—For some materials, changes may continue after the speci- This practice is intended to induce property changes associated with end-use conditions, including the effects of sunlight, moisture, and heat. B The irradiance set point given is typical for devices operated without irradiance control.
Moisture is provided by forced condensation, and temperature is controlled by heaters. Note Previous versions of this practice referenced fluorescent UV devices described by Practice G 53, which described very specific equipment designs.
Parts may be accommodated depending on size. Select panel sizes suitable for use with the exposure apparatus. The type and rate of degradation and the performance rankings produced in exposures to fluorescent UV lamps can be much different from those aetm by exposures to other types of laboratory light sources.
ASTM D classification asgm the standard practice for fluorescent UV and condensation exposures of paint and related coatings. Precision and Bias All references to exposures in accordance with this practice must include a complete description of the test cycle used. Global Reach Intertek is the atm leader with over 42, people in 1, locations in over countries. Interlaboratory comparisons are valid only when all laboratories use the same design of fluorescent UV device, lamp, and exposure conditions.

If in doubt, users should consult the manufacturer of their device for clarification. B The irradiance set point given is typical for devices operated without irradiance control. Refer to Practice G for more information about the construction and differences between uninsulated and insulated aatm panels.
The standard sample holders can hold one sample 3 x 12 inches 75 x mm or two samples 3 x 6 inches 75 x mm.
Where retention of characteristic property is reported, calculate results according to Practice D 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. 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 speci?
D Temperature is at equilibrium for either an uninsulated or insulated black panel, although the response of the insulated black panel d5487 be slower than that for the uninsulated black panel. How is it tested? It is the responsibility of the user d45887 this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
This practice also covers the preparation of test specimens, and the evaluation of test results. The spectral power distribution of light from d4857 UV lamps is significantly different from that produced in light and water exposure devices using other light sources.
Table 1 describes commonly used test conditions. Historical Version s – view previous versions of standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This practice also covers the preparation of test specimens, and the evaluation of test results. The ability of a paint or wstm to resist deterioration of its physical and optical properties caused by exposure to light, heat, and water can be very significant for many applications.
