Accelerated UV Testing Equipment

Name: Accelerated UV Testing Equipment
Brand: Xi'an LIB Environmental Simulation Industry

Accelerated UV testing equipment from LIB industry uses ultraviolet fluorescent lamps to reproduce the most damaging ultraviolet radiation found in natural sunlight. By combining UV irradiation, high temperature (Ambient ～ 90 ℃ ±2℃), high humidity (≥95% RH), condensation, and water spray, the system accelerates material aging processes that would normally take months or years outdoors—compressing them into days or weeks.

This accelerated approach enables fast evaluation of a material’s weather resistance, light fastness, color stability, and long-term durability, making it an essential solution for R&D validation, quality control, and material comparison testing.

The system supports 8 freely configurable UVA-340 or UVB-313 lamps, accurately simulating short-wave ultraviolet radiation with an irradiance of up to 0.15 W/m² across a 290–400 nm wavelength range.

Optional Model: UV-SI-260 and more customized models

Standard: ASTM G154, ASTM D 4329 – 05, ASTM C1257, ISO 4892, ASTM C1442, ASTM C1519, ASTM C793, ASTM D1148, ASTM D3424, ASTM D3451, ASTM D4101, ASTM D4811, ASTM D6577, ASTM D6662,SAE J2020

Adjustable light intensity with irradiance range: 0.3–20W/m² @ 340 nm, accommodating diverse testing requirements. Easy installation and maintenance with quick-change support to minimize downtime. Real-time display of operating current for each UV lamp facilitates monitoring of lamp status.	Accommodates 56 standard samples measuring 75mm × 150mm. Aluminum alloy plate with return flange ensures corrosion resistance and easy cleaning. For special test specimens, LIB can customize 3D sample holders.

Controller	Nozzles
Features an intelligent touchscreen control system with an intuitive interface. Allows setting parameters for illumination, condensation, spraying, temperature, and humidity, with support for programmed cycles. Includes built-in data logging for easy export and analysis.	High-precision water spray system simulates rain washdown and nighttime condensation. Part of a water recirculation system (with filtration), nozzles resist clogging. One row of nozzles on each side of the lamp tube. Ideal for combined UV + humidity + water spray testing.

FAQ - Accelerated UV Testing Equipment

Q1: Can this equipment be customized for large or special samples?
A: Yes. LIB industry provides customized Accelerated UV Testing Equipment, sample holders, lamp configurations, and control programs to meet non-standard testing needs.

Q2: What is the distance between lamps in the UV test chamber?
A: The distance between lamps in the UV test chamber is approximately 50 mm, meeting ASTM G154 and other related standards. This spacing ensures uniform UV light distribution, guaranteeing accurate and reliable weathering test results.

Q3: Does the Accelerated UV Testing Equipment have a water filtration system? Can water be reused?
A: Yes. The Accelerated UV Testing Equipment is equipped with an automatic water supply system and water filter to maintain stable water quality. During operation, water at the bottom of the chamber sustains high humidity. Overflow ports allow excess water to return to the water tank, enabling circulation and ensuring continuous testing while optimizing water use.
