Xenon Arc Test Instrument and UVA340/UVB313 UV Light Resistance Tester

When products are exposed to sunlight, UV radiation, heat, and moisture, materials such as plastics, coatings, and textiles often experience aging, discoloration, cracking, or brittleness. Accurately replicating these effects in a laboratory environment is critical for ensuring product durability, quality, and safety.

LIB's Xenon Arc Test Instrument and UVA340/UVB313 UV Light Resistance Tester deliver precise, standards-compliant accelerated aging solutions. These instruments simulate natural sunlight, UV radiation, temperature, humidity, and rainfall with repeatable accuracy, enabling manufacturers and R&D teams to evaluate outdoor material performance efficiently and reliably.

Xenon Arc Test Instrument

Full-Spectrum Sunlight Simulation
LIB's Xenon Arc Chamber reproduces natural sunlight across the 280–800 nm spectrum, including UV, visible, and infrared light. Irradiance is adjustable from 0.30–1.10 W/m²·nm, providing precise light conditions for accelerated aging tests.

Precise Temperature and Humidity Control
The chamber maintains Black Panel Temperature (BPT) between 63–77 °C ±2 °C and supports humidity cycles from 35–70 % RH. Spray and dark cycles are fully customizable, e.g., 102 minutes light + 18 minutes spray or 6 hours dark + 95 % RH.

Flexible Sample Handling
A rotating sample holder accommodates up to 42 flat or irregular samples. Standard thickness is 3 cm, while custom racks can handle up to 11 cm. Uniform airflow and irradiance ensure stable conditions even when the chamber is not fully loaded.

Standards Compliance
The Xenon Arc Chamber meets ASTM G151-19, ASTM D6695, ASTM G155, ISO 11341, ISO 4892-3, and ASTM D7869 standards, guaranteeing repeatable and internationally recognized testing results.

UVA340/UVB313 UV Light Resistance Tester

Targeted UV Simulation
LIB's UV Weatherometer focuses on UV degradation with high-stability UVA340, UVB313, and UVB351 lamps (40 W each, lifetime up to 5000 hours). It emits controlled UV light in the 290–400 nm range for accurate light resistance testing.

Temperature, Humidity, and Spray Control
The chamber maintains Black Panel Temperature (BPT) between 35–85 °C ±2 °C and humidity ≥95 % RH ±2 %. Adjustable spray cycles (1–9999 hours) simulate dew, rainfall, or condensation.

Specimen Capacity and Flexibility
It can hold up to 52 standard samples (75 × 150 mm) on aluminum holders. Custom 3D holders are available for irregular or oversized samples, ensuring uniform exposure across all specimens.

Standards Compliance
The UV Weatherometer complies with ASTM G154, ASTM G151, ISO 4892-3, and related international standards, delivering repeatable, traceable, and reliable results for R&D and quality control.

Customizable Solutions
LIB provides flexible sample holders, adjustable spray systems, extended filters, and PID-controlled programmable profiles. Instruments can be tailored to accommodate unique sample sizes, thicknesses, or testing cycles to suit various R&D and QC applications.

Q1: Xenon lamps are gas discharge lamps. What are gas discharge lamps? What is their principle?
A1: Gas discharge lamps generate light by applying voltage to electrodes in a sealed gas-filled tube, producing a high-temperature plasma that emits visible light.

Q2: The xenon lamp tube has a quartz inner layer and a borosilicate outer filter. How should "filter" be understood?
A2: The quartz inner tube houses the discharge, while the borosilicate outer layer and external optical filters control the spectrum, keeping emission in the 280–800 nm range.

Q3: The lamp tube has a lifespan of 1600 hours. Is there a way to extend it?
A3: Beyond 1600 hours, light intensity gradually decreases. To maintain test accuracy, the lamp should be replaced after its rated lifespan.

Q4: What is the maximum sample thickness for the standard rotating xenon lamp rack?
A4: Standard racks accommodate 3 cm thickness; custom racks support up to 11 cm to suit specific testing requirements.

Q5: If the test chamber is not fully loaded and there are gaps, will it affect humidity inside?
A5: No. Uniform airflow and irradiance ensure stable humidity, even when the chamber is not fully loaded.
