Weatherometer testing services

Micom Laboratories Inc. offers Weatherometer testing services for various materials and products to evaluate their resistance to solar and other UV exposure sources. Carbon based products ranging from coatings to wood and plastics form free radicals when exposed to UV radiations. These free radicals chemically react with oxygen to yield a photo oxidized product which modifies the product appearance and also its mechanical properties. There are different types of laboratory techniques available for doing UV exposures such as xenon arc, carbon arc, QUV and others. However xenon arc weatherometer testing uses a light source that emits most closely the emission spectrum of natural sunlight. Since these techniques are meant to deaccelerated light ageing to help predict how a material will perform in the field, you want to make sure the technique you use simulates your product's typical environment as close as possible. Weatherometer testing can be used to simulate both indoor and outdoor exposure as needed.

Xenon weatherometer testing techniques

Common accelerated weatherometer testing techniques for xenon arc are: ASTM G-155, ASTM D2565, ASTM D4459, ISO 4892, SAE J1885 and 1960. The main difference between the various techniques is the light intensity and other operational parameters such as temperature and relative humidity which also have a great impact on the photo-oxidation rate and the secondary chemical reactions. The equipment and the light source are the same. Should you need help defining what are the optimal operational parameters you should specify for your Weatherometer testing test plan, please feel free to contact our experts; they will be happy give you the proper answers.
