QUV Accelerated Weathering Tester

Model: QUV, ASTM D4329, ISO 4892, IEC 60335-1

QUV Accelerated Weathering Chamber adopts the fluorescent ultraviolet lamp that best simulates the UV segment spectrum in sunlight, and combines temperature control, moisture supply and other devices to simulate the sunlight (UV segment) that causes discoloration, brightness, intensity reduction, cracking, flaking, chalking, oxidation and other damage to the material, such as high temperature, high humidity, condensation, dark rain cycle and other factors, and at the same time, through the synergy between ultraviolet light and moisture, the single light resistance or single moisture resistance of the material is weakened or invalidated, which is widely used in the evaluation of the material's climate resistance. The equipment has the characteristics of providing the best sunshine UV simulation, low maintenance cost, easy to use, automatic operation of the equipment with control, high degree of automation of the test cycle, good light stability, and high reproducibility of test results. 


The tower UV test chamber meets the test standards:

Plastics laboratory light source exposure test method ASTM D4329-05

Instrument operation method for UV aging of non-metallic materials ASTM

Rubber and plastic material artificial climate aging test method fluorescent ultraviolet lamp

Fluorescent UV lamp ISO-4892-1:2016, ISO-4892-2:2013, ISO-60335-1:2020.
