test chambers uv weathering screaning test chamber


The UV weather resistance test chambers from Weiber are specially designed equipments that are used for the testing of a wide variety of materials including rubber, organic compounds, and non-ferrous materials, plastic and building materials for their ageing and corrosion resistance towards UV irradiation. These test chambers are designed to provide natural weathering conditions by simulating complete UV spectrum that ranges from 280-400 nanometres. This UV spectrum includes the most aggressive UV-B range comprising of very short wavelengths ranging from 280-315 nm that are notorious for causing maximum material damage. The UV radiations can cause significant degradation effects in polymer based materials, ranging from simple discolouration of surfaces to extensive mechanical damage. Surface discolouration severely affects the aesthetic appeal of the product, but mechanical damage can threaten the structural integrity of building materials and the performance of the building product over a period of time

The effect of UV radiation can be frequently observed in the affected materials in the form of surface discolorations, erosion and fading of surfaces, commonly known as chalking and surface cracks. Themechanical damage is generally not visible through the surfaces and manifests itself in the form of changes in tensile strength, elongation in break and other physic-chemical properties. The UV weather resistance test chambers play a significant role in determining the stability and resistance of polymers, composite materials and other protective materials in the presence of UV rays and their appropriate usage.
