QUV Accelerated Weathering Test
● QUV weather resistance Tester is fast and economical. Fluorescent UV lamps can simulate the sun's ultraviolet rays very well. However, QUVs lack the longer wavelengths needed to test some materials.
● Short-wave UV: The QUV Tester provides good sunlight simulation in the short-wave UV region, making it an excellent choice for testing durable materials such as coatings, roofs, and plastics. Its fluorescent UV lamp is spectrally stable for improved reproducibility and repeatability.
● Condensation: The condensation system (relative humidity 100%) of the QUV Tester is an effective outdoor moisture erosion acceleration measure. Moisture penetration may cause damage, such as blistering of the paint.
Q-SUN
● Q-SUN xenon arc Tester can reproduce all sunlight including ultraviolet, visible light and infrared light. It is especially useful for testing dyes, pigments, textiles, inks and interior materials. However, xenon arcs are inherently less stable than fluorescent lamps, and water spray is not as practical as the condensation cycle of a QUV Tester.
● Full-spectrum sunlight: Xenon arc lamps produce full-spectrum sunlight. With the help of optical filters, the Q-SUN Tester can replicate daylight and sunlight through window glass exposure conditions.
● Humidity and Humidity: Q-SUN Tester is ideal for photostability testing of humidity sensitive materials such as textiles, inks, cosmetics and pharmaceuticals. It has great water retention properties and is also a suitable xenon Tester for accelerated car varnish "Jacksonville" acid etch tests.
Q-Lab Outdoor Test
● Q-Lab in Arizona and Florida represents the world standard for sunlight and humidity. They can most realistically predict product performance. While some exposure tests can take years to complete, some techniques can yield useful data in the short term.
● Natural Florida Weathering: Florida's subtropical regions are exposed to sunlight, heat and lots of moisture. Most materials should be exposed to natural Florida benchmarks. Even though natural testing may take months or years to complete, the results are the most realistic and provide benchmark data for accelerated testing.
● Arizona's natural weathering: Arizona's desert exposure lacks moisture, but has more UV rays than Florida, and extreme temperature swings can also cause heat shock.
● Q-TRAC Natural Sunlight Concentrator: In just one year, specimens can receive 5 years of natural sunlight in Florida.
