In order to avoid negative effects on the durability, UL Solutions offers extensive tests to determine environmental influences on the respective components. With standardized and customer-specific test procedures we are able to help you validate the long-term performance required by automobile manufacturers using accelerated test methods. This ensures the quality of your components throughout the whole product life cycle.
Our test methods comply with most international standards and requirements of the Automobile OEMs.
Artificial Weathering (Light and UV Resistance)
Weather impacts the long-term behavior of polymers and coatings. Possible color, surface and mechanical changes can be simulated on test specimens as a result of controlled weathering influences.
In these tests, changes to automotive components due to weather influences are assessed. Various test methods offer the possibility of simulating the different weather conditions for interior and exterior use.
We offer test methods according to international standards as well as to automotive OEM specifications.
Common standards for Weather-Ometer, Xenotest, Suntest, UV-Test
ASTM G26, ASTM G151, ASTM G155, DIN EN ISO 4892, ISO 75220, SAE J2412, SAE J2527, VDA 75202, PV 1303, PV 3929, PV 3930, or equivalent standards
Climate Change Test
To simulate different climatic conditions (e.g. seasons in different world climate zones), UL Solutions carries out standardized and customer-specific accelerated climate change tests of your products and components.
A cyclic climate change test (temperature and humidity) conducted in our test chambers on test specimens and finished parts simulates certain environmental stress. Weak points in exterior or heavily stressed interior components are detected early on and can be corrected.
Common standards for climate change testing
PV 1200, DIN 40046, IEC 60721-4, IEC 60068-2, GMW 14729, PR 303.5, PV 2005, or equivalent standards
Thermal Aging
The aging behavior of polymeric materials can be analyzed through accelerated aging test methods, by storing specimens at different temperatures in hot-air-ovens.
The respective test specimens are removed from the ovens in determined time intervals for testing. The reduction in the material properties is used to measure the aging behavior. Typical test methods for determining these changes are mechanical, electrical and surface tests as well as optical evaluations. Other methods are possible and depend on the specific application.
Common standards for thermal aging and heat resistance
IEC 60216-1, VDE 0304, UL 746 B, TPJLR.52.352, D45 1139 PSA, D45 1234 PSA, PV 3355, or equivalent standards
Ozone Aging
The effect of ozone on plastics (thermoplastics, elastomers) can lead to the formation of cracks and consequently significantly reduce the service life of products.
Therefore, most types of rubber materials must be protected by additional antioxidants and ozone waxes. The aging of the rubber by ozone is simulated and measured within a few days in the ozone test chamber.
Common standards for ozone aging
DIN 53509, ASTM 1149, ISO 1431, VW 2.8.1 55 15 2, JIS k 6259, NF T46-019, BS 903 A43, GB 7762, PV 3305, PV 3316, or equivalent standards
