Outdoor plastics and coatings face a harsh reality: sunlight, heat, and moisture break down color, gloss, and mechanical strength. To accelerate this process in the lab, you need a chamber that mimics real solar exposure, delivers repeatable results, and aligns with the strictest global test standards.
LIB's ASTM D2565 test chamber delivers exactly that-controlled UV, temperature, and water spray cycles-so you can predict years of outdoor performance within weeks.
ASTM D2565: Standard Practice for Xenon Arc Exposure of Plastics Intended for Outdoor Applications
Standards Compliance
To ensure your results are accepted by regulators, customers, and certification bodies, LIB's ASTM D2565 chamber must meet the world's benchmark standards:
- ASTM D2565: Xenon-arc exposure of plastics intended for outdoor applications.
- ASTM G151: General practice for operating laboratory weathering devices.
- ASTM G155: Xenon-arc test methods with daylight, window, and extended UV filters.
- ISO 4892-2: Plastics-Methods of exposure to laboratory light sources-Xenon-arc lamps.
- ...
By aligning with these standards, LIB ensures your accelerated tests reflect real-world degradation, making results trusted and certifiable.
1.1 This practice covers specific procedures and test conditions that are applicable for xenon-arc exposure of plastics conducted in accordance with Practices G151 and G155. This practice also covers the preparation of test specimens, the test conditions best suited for plastics, and the evaluation of test results. NOTE 1-Previous versions of this practice referenced xenon-arc devices described in Practice G26, which described very specific equipment designs. Practice G26 is being replaced by Practice G151, which describes performance criteria for all exposure devices that use laboratory light sources and by Practice G155, which gives requirements for exposing nonmetallic materials in xenon-arc devices. Practice G26 will be balloted for withdrawal before December 2000. 1.2 This standard does not purport to address all the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. NOTE 2-This practice is technically equivalent to ISO 4892-2.
Apparatus
5.1 Use xenon-arc apparatus that conform to the requirements defined in Practices G151 and G155. 5.2 Unless otherwise specified, the spectral power distribution (SPD) of the xenon lamp shall conform to the requirements of Table 1 in Practice G155 for a xenon lamp with daylight filters.

ASTM D2565 test chamber Temperature Range: Ambient～100℃±2℃; Humidity Range: 50%~98% RH; Irradiance: 35~150 W/㎡; BPT Temperature: 35℃～85℃±2℃; Free calibration; Color fastness test; Xenon lamp radiation; Two independent water systems, effectively protecting xenon lamp |
Test Precision & Repeatability
Accurate simulation requires tight control of UV, temperature, and water cycles:
Irradiance Control: 0.35 ± 0.02 W/m² at 340 nm, matching ASTM G155 Cycle 1.
Temperature Accuracy: Black panel temperature 63 ± 2 °C during light exposure.
Spray Cycles: 102 minutes of light + 18 minutes light with water spray, programmable for continuous or intermittent wetting.
Water Quality: Conductivity < 5 μS/cm and silica < 1 ppm, preventing spots or deposits.
Sample Uniformity: Rotating rack with equal exposure ensures no sample bias.
These parameters guarantee repeatable degradation patterns-yellowing, cracking, gloss loss-so comparative tests are valid across batches.

Operational Efficiency
R&D teams need a chamber that is intuitive, automated, and resource-conscious:
One-Touch Operation: Color touchscreen controller with preloaded ASTM/ISO cycles.
Remote Access: Ethernet + USB for real-time monitoring and report export (CSV/PDF).
Water Recycling: Closed-loop condensate recovery saves up to 50% water use.
Flexible Filters: Quick-swap daylight, automotive glass, or extended UV filters for different industries.
This means less downtime, faster test setup, and lower operational cost per sample.
