Advanced Environmental Simulation for Material Performance
An Accelerated Weathering Chamber is key in the plastic and polymer industry for testing how materials hold up against tough conditions like UV light, rain, and temperature changes. It helps check the durability of products, making sure they can last a long time and stay strong even when exposed to the elements. This chamber speeds up the aging process, allowing manufacturers to quickly find out if their products can withstand outdoor use. It’s an essential tool for ensuring that everything from car parts to outdoor furniture is reliable and tough.

Testing Standards
Which Standard Might Your Customer Specify?
Standards give the laboratory a common way to run and report a test. The right one depends on the material, where it is used in the vehicle and the customer’s requirement. Here are the main references you may come across.
Methods of exposure to laboratory light sources for plastics. Covers xenon arc lamps with daylight and window-glass filter conditions for interior and exterior plastic applications. Primary reference for the SX/6500/H.
Standard practice for operating xenon arc light apparatus for exposure of materials. Covers equipment setup, irradiance control, filter selection and cycle operation — foundational method for xenon weathering tests.
General principles for exposure and test methods for plastics to laboratory light sources. Covers specimen preparation, mounting, exposure conditions and evaluation of colour change, gloss and mechanical properties.
Methods of exposure to laboratory light sources. Part 3 covers fluorescent UV lamps for plastics — specifies UVA 340 nm or UVB 313 nm lamp type, irradiance setting, moisture condensation cycle and specimen evaluation criteria.
Standard practice for operating fluorescent UV lamp apparatus for exposure of nonmetallic materials. Covers cycle design, irradiance control and specimen mounting — primary equipment standard for UV weathering of plastics.
Standard practice for fluorescent UV exposure of plastics. Specifies lamp type, irradiance, condensation cycle and exposure duration for evaluating colour change, gloss retention and mechanical property degradation.
General principles for exposure and test methods for plastics to laboratory light sources. Provides guidance on specimen preparation, mounting, exposure conditions and evaluation of results applicable to all UV-exposed plastic materials.
Methods of exposure to laboratory light sources. Part 3 covers fluorescent UV lamps for plastics — specifies UVA 340 nm or UVB 313 nm lamp type, irradiance, moisture condensation cycle and specimen evaluation applicable to benchtop UV chambers.
Standard practice for operating fluorescent UV lamp apparatus for exposure of nonmetallic materials. Applicable to both full-size and benchtop UV chambers — covers irradiance control, cycle design and specimen mounting.
Standard practice for fluorescent UV exposure of plastics. Specifies lamp type, irradiance, condensation cycle and exposure duration for evaluating colour change, gloss retention and mechanical property degradation in compact benchtop setups.
