The DY-XD-80L is a programmable, air-cooled xenon arc weathering chamber. A long-arc xenon lamp reproduces the full solar spectrum, and controlled temperature, humidity and water spray cycles accelerate the outdoor weathering of plastics, coatings, rubber, textiles, leather and automotive interior and exterior trim. Colour shift, gloss loss, chalking, cracking and mechanical strength decay can be assessed in a reproducible laboratory cycle.
The instrument is built to GB/T 16422.2 / ISO 4892-2 and ASTM G155. Irradiance is adjustable at 340 nm and 420 nm as well as across the 200–800 nm band, with interchangeable quartz filters for direct sunlight or daylight behind window glass.
Applications
Natural outdoor exposure may need months or years before a formulation shows visible degradation. A xenon arc chamber intensifies irradiance and combines it with programmable dark periods and spray cycles, so material screening, incoming inspection and finished-goods weatherability verification can be completed in a fraction of the time. Typical users are research institutes, independent testing laboratories, and the R&D and QC departments of plastics, coatings, automotive parts, textile and leather producers.
The enclosure is divided into a test zone, a lamp service zone, an instrument compartment and a machine room, with lockable PU castors. A digital lamp supply and dedicated igniter drive the lamp, which is cooled by an independent centrifugal blower with temperature interlock; the lamp extinguishes automatically on blower failure. A calibrated irradiance sensor or full "sun eye" closed-loop control can be added.

Standard Scope International reference GB/T 16422.2 Plastics — laboratory light exposure using xenon arc lamps ISO 4892-2 ASTM G155 Operating xenon arc light apparatus for exposure of non-metallic materials ISO 4892-2 SAE J2527 Accelerated exposure of automotive exterior materials using xenon arc ISO 4892-2 GB/T 1865 Paints and varnishes — artificial weathering and artificial radiation ISO 11341 GB/T 8427 Textiles — colour fastness to artificial light: xenon arc fading lamp ISO 105-B02 AATCC TM16 Colorfastness to light ISO 105-B02 Ordering information
Installation requires a level, ventilated site at 5–28 °C and ≤85 %RH, clear of strong vibration, electromagnetic fields and flammable or corrosive atmospheres. Use distilled or deionised water at 0.1–0.25 MPa for spray and humidification, with an independent breaker and an earth resistance below 4 Ω. When only the UV band is needed, consider the fluorescent UV aging chamber; for temperature cycling and damp heat, see the constant temperature and humidity chamber. Lamp power, filter sets and cooling method can be configured to the governing test standard.
