UV Light Accelerated Weathering Tester Chamber Manufacturer
A UV weathering test chamber is a type of environmental test chamber designed to simulate the damaging effects of sunlight, UV radiation, moisture, and temperature on materials — all within a controlled lab environment. As manufacturers of UV weathering test chambers, Effective Lab India allows every quality engineer, R&D team, and procurement manager to identify the long-lasting materials and save on false investments. Our chambers are compliant with worldwide recognised standards such as ASTM D4329, ISO 4892-1/3, ISO 11507, EN 927-6, EN 12224, and JIS D 0205 — giving your test results the value in the eyes of customers.
UV Light Accelerated Weathering Chamber
The UV weathering test chamber — also known as a UV accelerated weathering tester or UV light aging chamber — subjects test material to cycles of ultraviolet light, heat and humidity. These cycles condense years of outdoor exposure into days or weeks in a controlled lab test. In consequence, manufacturers can anticipate how their materials will behave under real-world climates long before those products ever meet the market. Within the chamber, UVA-340 or UVB-313 fluorescent lamps mimic the intensity of ultraviolet light in natural sunlight. The UVA-340 lamp emits light that replicates the sun’s between 300–400 nm — the band of wavelengths most responsible for photodegradation. The UVB-313 lamp delivers a more intense exposure for efficient comparative test. Both lamp types are fully integrated with our HMI touchscreen-controlled system, where precise programme profiles can be set, saved and repeated.
Working Principle of UV Accelerated Weathering Test Chamber
The chamber, powered by renewable energy, operates on a straightforward yet scientifically sound premise: accelerated weathering through controlled UV exposure and cycles of heat and moisture. This is what happens in a normal testing cycle:
- UV lamps (three or more 40W fluorescent lamps): The radiation generated by the lamp ranges from 250nm to 400nm, allowing it to strike the surface of each specimen and activate photochemical degradation reactions like natural sunlight.
- A temperature control system keeps the chamber at the target test temperature (ambient to 70°C), providing uniform thermal stress for all cycles.
- A programmable water spray system to simulate rain and dew with programmable intervals. The water flow is kept below 6 litres per minute to avoid displacing the specimens.
- • The specimen turntable spins at 15 RPM, allowing all samples to be exposed evenly and without difference at the same time.
- A Corrosion-Resistant PT-100 sensor constantly monitors the chamber temperature and sends feedback to the digital controller for real-time correction.
The result is an accelerated degree of real-world weathering. Barring complications, however, 500 hours of UV chamber testing can equate to several years' worth of outdoor exposure — this is material- and geographic-location-dependent.

Frequently Asked Questions
Â
Q1. What is the difference between a UVA-340 and a UVB-313 lamp?
The UVA-340 lamp closely matches the solar spectrum between 300–400 nm and is recommended when realistic outdoor weathering simulation is the priority. The UVB-313 lamp provides more aggressive, short-wave UV exposure below 300 nm for faster comparative testing. Your required test standard will specify which lamp type to use.
Q2. How many hours of UV chamber testing equals one year of outdoor exposure?
This depends on the material, geographic location, and test conditions. As a general guideline, 500–1,000 hours of accelerated UV testing under ASTM D4329 conditions approximates 1–3 years of outdoor exposure in a temperate climate. For exact correlation, refer to your material-specific test standard.
Q3. What physical changes does the UV chamber detect?
The chamber can reveal colour change (delta-E measurement), surface chalking, gloss loss, cracking, delamination, loss of tensile strength, and embrittlement — all caused by UV-induced photodegradation of polymer chains.
Q4 Is the UV weathering test chamber safe to operate?
Yes. Our chamber includes an automatic safety interlock that cuts power to all UV lamps the moment the chamber door is opened. Operators should still wear UV-protective eyewear when working near the chamber during a running test cycle as a precautionary measure.
Q5 Do you offer calibration and after-sales service?
Yes. Effective Lab India provides NABL-traceable calibration services, annual maintenance contracts (AMC), and genuine spare lamp replacements for all models we supply. Our service team covers major industrial cities across India.

UV safety in the Ultraviolet weathering test chamber is very important because prolonged exposure to UV rays can have harmful effects on the eyes and skin. UV rays cause Sunburn, skin cancer etc. So, for the protection of human skin, it is important to take precautions such as wearing protective clothing, and sunglasses.Â
There are three main types of weathering which include.
- Mechanical weathering
- Biological weathering
- Chemical weathering
UV stands for Ultraviolet. It is a type of electromagnetic radiation that comes from the Sun. UV rays are invincible from the human eyes but can have harmful and beneficial effects on human health.
