3. ASTM D4587 - Standard Practice for Fluorescent UV-Condensation Exposures of Paint and Related Coatings. ASTM D4587 includes a selection of test conditions for accelerated exposure testing for coatings and related products in fluorescent UV and condensation devices, conducted in accordance with ASTM practices G151 and G154. 4.
• Test Paint with a UV Light. To ensure the desired glow effect, test your paint under a UV light (also known as blacklight) during the painting process. This helps to gauge the intensity of the glow and make any necessary adjustments. • Seal Your Work. UV-reactive paints can be sensitive to weather and other environmental factors. Image 2: Range of Delta E differences from an unexposed control with corresponding ASTM Lightfastness categories. Seeing the amount of change allowed for each of the ASTM Lightfastness Categories might come as a surprise for many people who have come to expect that Lightfastness I means a color will not fade or change to any degree, or at most .Applied Technical Services has dedicated itself to the pursuit of quality since our founding in 1967. While the 50+ intervening years have seen us expand the scope of our services — now offering an array including testing and analysis, consulting engineering, industrial inspections, equipment calibrations, personnel training, and forensic investigations — we have always balanced this .Here are some key points regarding accelerated weathering testing that can be accomplished by the Qualitest range of UV Test Chambers and UV Accelerated Weathering Testers: Available UV Test Chamber and UV Accelerated Weathering Tester Models: Quali-UV100 Benchtop UV Test Chamber. Quali-UV200 UV Light Accelerated Test Chamber
UV stability testing is a method of accelerated weathering that reproduces the effects of long-term exposure to sunlight in a more time-efficient manner. This kind of testing exposes sample materials to UV light and high temperatures, either cyclically or statically, and may include exposure to moisture to assist in simulating real outdoor service conditions.

ASTM D4587-11(2019)fluorescent UV condensation exposures of paint and related coatings e1 standard practice; ISO 4892-3:2016(en) The Use of Fluorescent UV Lamps in the Laboratory, Third Part Plastics; Ed. 3.0 en:2018 IEC 60068-2-5; Test S: Ground-Level Solar Irradiation Simulation and Solar Radiation Testing and Weathering Procedures You can date a ribbon by testing it under the UV light by finding out what type of fiber it has. If a ribbon appears to glow or display fluorescence then that means it has artificial or man made fiber. 4. Authenticating Arts. Modern paint will fluoresce under a black light. This will allow you to easily inspect paintings for touch-ups and repairs.
We perform UV testing to determine UV protection. Paint manufacturers send their paint to UV testing labs to determine the level of UV resistance, in order to put the information on their packages. The testing determines how long the paint will last before fading or cracking, in order for manufacturers to modify chemicals present in the paint. .Starglow Clear UV Paints are designed to be durable, highly versatile and very long-lasting, as underpinned by our unique 10 year guarantee.
