ISO 4892-82 Chamber Type UV Weathering Accelerated Ageing Test Equipment
ISO 4892-82 Chamber Type UV Weathering Accelerated Ageing Test Equipment
Standards & Clauses:
The UV Weatherproof Test Chamber is designed and manufactured according to the standard requirements of ISO 4892-82, ASTM G 154, ISO 4892-3; ISO 11507; ASTMD 4329, and etc.
Product overview:
This product is suitable for the fluorescent ultraviolet lamp method in the light source exposure method of various materials laboratory, mainly for the changes of materials placed outdoors, and the durability test of new materials and improved formulations and products.
The product adopts fluorescent ultraviolet lamps that can best simulate the UV spectrum in sunlight, and combines temperature control, humidity supply and other devices to simulate sunlight ( UV segment) high temperature, high humidity, condensation, dark cycle and other factors, and through the synergistic effect between ultraviolet light and moisture, the light resistance or moisture resistance of the material is weakened or invalid, so it is widely used in the evaluation of weather resistance of materials.

Precautions
The machine should be stored in a ventilated, clean and dry place. The casing is kept clean and dry.
After the equipment is used normally, pay attention to the cleanliness of the surface of the lamp used to prevent the irradiance of the lamp and the service life of the lamp from being affected. If there is any pollution, use alcohol to wipe the surface. When the service life of the lamp tube expires, the lamp tube must be replaced on time.
Water tank maintenance: Use pure water and replace the water once a week. If it is not used for a long time, the water in the water tank should be drained.
Sink maintenance: keep the sink clean and dry when not in use.
