To simulate outdoor weathering, an accelerated weathering tester exposes materials to alternating cycles of UV light and moisture at controlled, elevated tensile strength testing for membranes temperatures. They help manufacturers project how long material may last when exposed to outdoor conditions within a fraction of that time. As a weather testing equipment pioneer, a consistent experience in product durability testing is ensured for either a seasoned manufacturer or a new one by Presto Enviro, backed by decades of trust and innovation. This method can measure a product’s ability to resist deterioration of mechanical, electrical, and optical characteristics when exposed to light and heat. This method enables a rapid evaluation of a material’s durability and resistance to degradation, providing valuable insights into its long-term performanc
Comparative durability data can be obtained for a wide range of materials such as coatings, adhesives, polymers, metals, wood, textiles and building materials. Amongst the most extensive business ventures across the globe having a proven track record, Presto Enviro equips manufacturers with cutting-edge technology to be well ahead of the competition.

The most popular accelerated weathering testing is covered by ASTM G154.This test is exposing samples to a cycle of 8 hours of UVA-340 light at a temperature of 60’C, followed by 4 hours of condensation at 50’C for a total of 500 hours (21 days) of exposur
Rather than waiting years to see how materials wear out naturally, these tests use special machines (like UV chambers) to speed up aging, giving results tensile strength testing for membranes much faster. This helps scientists quickly see how a material might fade, crack, or break down after years of outdoor exposure- without waiting for years. This method enables a rapid evaluation of a material’s durability and resistance to degradation, providing valuable insights into its long-term performance. The test is performed using specialized equipment like UV weathering chambers or QUV testers, which expose materials to cycles of UV light and moisture. Failure to weather results in low-quality products, returns, and by extension customer dissatisfactio
The Q-TRAC solar concentrator uses actual sunlight as the light source and is exceptionally useful for testing highly-durable materials with exceptionally long lifetime expectations. For an overview of these tests, see our webinar Accelerated Outdoor Weathering Testing. Rotating rack and flat array testers are both expressly permitted in nearly every major standard, and research studies have confirmed that they deliver similar results in many cases. Moisture is delivered to specimens primarily by water spray, in addition to controlled relative humidity.
All cycles vary between 4-hour or 8-hour light and 4-hour condensation periods, except for some minor differences in cycle 5 (20 h light) and cycle 7 (15 min spray). An ASTM G154 UV test chamber, or a QUV test chamber, is equipment used for simulating the degradative effects of sunlight and water on materials. UV-B lights tends to accelerate or create “brittleness” or an ageing process not typically occurring outdoors. UV-A bulbs can offer Daylight and UV behind window glass exposures.UVA-340 offfers the best correlation to outdoor exposures because it is the best simulation of sunlight from 295 to 365 n
By measuring these parameters, the test replicates outdoor weathering conditions in order to test material degradation. This assists manufacturers in anticipating how their material will behave long-term under exposure to outdoor environments, providing durability, tensile strength testing for membranes colorfastness, and resistance to cracking, fading, or other types of degradation. This allows manufacturers and researchers to assess the durability and weather resistance of products in a shorter time than natural exposure would require outdoors. It accelerates the aging of non-metallic materials, such as plastics, coatings, and textiles, by exposing them to UV radiation, water (usually as condensation), and heat.
