For a full description, see LL-9025 - Outdoor Weathering Exposure Procedures, or contact Q-Lab to discuss which option is suitable for your test program.

The specific type of specimen mounting technique and exposure angle both have a significant effect on solar energy dosage, specimen temperature, and time of wetness. In addition, specimens may be placed near or under vegetation to promote growth.

Mildew Tests: In this Florida exposure, panels are typically positioned at a 90º north to reduce sunlight, decrease surface temperatures, and increase moisture.

Salt-Accelerated Outdoor Corrosion: Direct exposures with salt spray can produce fast and realistic corrosion, particularly for coated metals.

AIM Box (Automotive Interior Materials): These under glass exposures simulate the environment inside an automobile and are suitable for mounting larger components like dashboards.

Under glass black box exposures are used to test interior automotive materials.

Black Box:These tests reproduce conditions found on the horizontal surfaces of a vehicle, including higher temperatures and wet times.

Specimens are behind 3 mm window glass which will filter out short-wave UV.

Under Glass: These exposures are used to test interior-use materials, such as textiles and printing inks.

Different exposure angles and mounting methods are used for different applications. Specimens are securely mounted with their front surface facing the sun.

Direct Exposure:Direct exposures are used to test many exterior-use materials, such as industrial coatings.

Various specimen mounting and exposure techniques are available for natural outdoor exposure testing in Florida: Biodegradation, including mold, mildew, fungus and algaeĪ Variety of Different Exposure Techniques.Moisture sensitivity of products like coatings, building materials, and some plastics.Mechanical strength loss and physical deterioration.Cracking, peeling, chalking, and blistering.The extremely sunny, humid, and warm climate has been proven especially useful for certain types of testing including: It is this synergistic effect of UV, moisture and heat that makes Miami the ideal location for testing durability of materials in outdoor environments. Our Florida site has high-intensity sunlight, high annual UV, high year round temperatures, abundant rainfall and very high humidity. One year of Florida sunshine can equate to several years of weathering elsewhere. Florida subtropical weathering exposures are not only realistic, they are also accelerated. Why Florida?įlorida is the internationally recognized benchmark location for outdoor exposure testing.
