Lightfastness and weather durability testing of consumer electronic products and components is rapidly growing. More types and greater numbers of products are mobile and subject to exposure to various sources of light, such as direct sunlight, and different climatic conditions.
Consumer electronics OEMs are concerned with maintaining their brand image and meeting customer expectations for quality. This includes not only functional performance, which can be negatively influenced by the environment, but also color and appearance, as well as mechanical and physical properties.
Therefore, major OEMs require environmental durability lightfastness or weathering qualification testing on new materials and designs, and acceptance testing throughout their supply chains during the product lifecycle.
Environmental exposure testing to the effects of light, heat and moisture are mostly performed in specialized laboratory exposure test instruments, based on xenon-arc lamp technology. With the proper selection of optical filters, test specimens may be exposed to artificial full-spectrum direct sunlight, sunlight as filtered through window glass or automotive glazing, or to artificial indoor lighting, as appropriate.
Temperatures, including specimen test surface temperature and moisture, as relative humidity, or water sprays, provide complete simulation of specific outdoor, indoor, automotive interior, or other climatic conditions. These durability tests address the longer-term material degradation from exposure to in-service environmental stresses and are different from many of the accelerated reliability and “torture tests” that are used.
For more than 100 years, Atlas Material Testing Technology has been a leader in materials durability testing, offering a complete line of weathering testing instrumentation, laboratory, and outdoor testing services. Atlas products are designed and manufactured to conform to international and industry standard test methods, including ISO, ASTM, DIN, JIS and numerous others.
The Atlas Ci4400 Weather-Ometer provides easy and effortless operation, unmatched uniformity, increased capacity and a sleeker design, delivering unparalleled value and performance. It offers a user-friendly touchscreen interface and ergonomic features. Furthermore, design and engineering innovations in the airflow, irradiance and control systems have dramatically reduced variability in critical test parameters. As a result, the Ci4400 achieves new levels of temperature, humidity and light exposure uniformity.
