Weathering Testing

Weathering Testing

Applied Technical Services performs a variety of weathering testing methods to determine the lifespan of client materials. Our ISO 17025 (A2LA) accredited lab can ascertain a sample’s resistance to heat, cold, thermal shock, humidity, salinity, solar radiation, altitude, and determine subsequent color or physical property changes, to name a few.

Weathering Exposure
Products degrade over time. Exposure to environmental stress factors speeds this process along, but even the strongest metallic and polymeric materials weaken and fail eventually. Manufacturers consider this fact when selecting materials for the design of their products; no one wants patio furniture that deteriorates or a car dashboard that cracks when exposed to sunlight, for instance.

Knowing what the materials of construction can withstand allows manufacturers to ensure the quality of their product and approximate its lifespan when used under expected conditions in its intended manner. To discover the physical, thermal, and chemical properties of their product and its constituent materials, manufacturers send samples to third-party testing companies like Applied Technical Services. We perform a variety of weathering testing methods to determine the resistance of various products.

What follows is a list of the most common standards to which these tests are executed. Click on the titles to learn more about a specific test:
