THE BENEFITS OF LOW-TEMPERATURE TESTING What is the Low-Temperature EMMA ®/EMMAQUA ®? The Low-Temperature EMMA/EMMAQUA (LT-EMMA/ EMMAQUA) is Atlas’ latest innovation that utilizes “cool mirror” technology in natural exposure testing. This new outdoor testing device delivers more than 5 years of equivalent radiation exposure as would be received in a standard outdoor testing rack in South Florida in a single year, but with much cooler sample temperatures when compared to traditional EMMA/EMMAQUA testing. What are the Benefits? The new LT-EMMA/EMMAQUA device performs accelerated testing...

Effects of Low-Temperature Testing The Low-Temperature EMMA®/EMMAQUA® device provides a solution to long-standing concerns over outdoor accelerated weathering of temperature-sensitive materials (Figure 2). Analyzing black standard temperature (BST) and black panel temperature (BPT) measurements on the Atlas LT-EMMA/EMMAQUA device has shown that temperatures remain significantly lower than that of standard ASTM G90 devices (Figure 3) while successfully achieving high irradiance levels (Figure 4). Comparison of Black Standard Exposure Temperatures Comparison of Exposure Irradiances 3.5 3...
