UV radiation test is to determine the durability of the product performed by aging test chamber with UV fluorescent lamps. The QUV Accelerated Aging Tester simulates the negative effects of sunlight, rain and condensation on test samples. In a few days or weeks, the QUV UV tester can reproduce the damage that occurs over months or years outdoors. To simulate outdoor weathering, the QUV accelerated tester exposes materials to alternating cycles of UV light and moisture at controlled, elevated temperatures. It simulates the effects of natural sunlight and artificial irradiance using special fluorescent UV lamps. It simulates also dew and rain with condensing humidity and/or water spray.
The tests are conducted using the Q-Lab, QUV/spray/rp - Accelerated Weathering Tester. Depending on the type of material, the tests are conducted in accordance with:
EN 1297:2004 Flexible sheets for waterproofing - Bitumen, plastic and rubber sheets for roof waterproofing - Method of artificial ageing by long term exposure to the combination of UV radiation, elevated temperature and water.
EN 13859-1:2014 - Flexible sheets for waterproofing - Definitions and characteristics of underlays - Part 1: Underlays for discontinuous roofing.
EN ISO 4892-3:2016 Plastics - Methods of exposure to laboratory light sources - Part 3: Fluorescent UV lamps.
As part of the testing of the PM&VL7 research line, Rothoblaas membranes, tapes and their connections were examined.
