All Suntek products are tested using colorfastness to light. This refers to a fabric's ability to resist fading when exposed to sun. The test used to measure colorfastness to light is AATCC 16 option 1 or 3. "The AATCC 16 Option 1 and 3 are test methods of the American Association of Textile Chemists and Colorists. In AATCC 16 Option 1 a Carbon-Arc lamp is used as the light source and in AATCC 16 Option 3 a Xenon-Arc lamp is used. Under both methods a strip of fabric, part of which is protected by a special paper card, is placed in a fadometer and exposed to 40 hours of accelerated fading units. After the exposure the difference in color between the exposed and protected parts of the fabric are compared to the AATCC gray scale and the degree of fading is rated." Grade 5 = no fading Grade 4 = slight fading Grade 1 = high degree of fading If you demand quality. Only Suntech products endore the ellements of the sun.
