27 sty 2023 · Significance and Use. 5.1 The use of this apparatus is intended to induce property changes consistent with the end use conditions, including the effects of the UV portion of sunlight, moisture, and heat.
Ultraviolet (UV) testing from an accelerated aging perspective finds its roots in photochemistry. This part of chemistry studies light as an energy source to induce chemical reactions (i.e. light is used to provide the required activation energy so that one or more chemical reaction start occurring).
