UV Weathering Test- UV-stability tested by Fraunhofer ISE

PublishTime：2022-07-24

●Commissioned by HellermannTyton, the Fraunhofer Institute for Solar Energy Systems ISE carried out an extended UV weathering test according to IEC 61215, subsection 10.10. For this purpose, four cable ties of different materials were fastened under load to test cylinders and then exposed to UV radiation at controlled intervals inside a test chamber. Thereafter, the ties were subjected to a loop strength test performed according to section 9.5.1 of the VDE Institute's DIN EN 62275:2010.07. The specimens spent up to 1,600 hours in the test chamber and were exposed to a UV dose of 156.78 kWh/m2. This amount of artificial irradiation complies with the assumption that Central Europe is exposed to natural solar irradiation of 1,000 kWh/m2 per year, with about 5% of this being in the damaging UV range. The test corresponded to approximately 3 years of outdoor exposure. Since the intensity and coherence of UV irradiation in the test chamber are not met under natural conditions, these values will be compared to the results of an on-going comparative outdoor exposure over 3 years in Freiburg, Germany and the Negev Desert in southern Israel.
●The graphs below depict the mean results of the cable tie loop strength test after artificial UV weathering. The natural-coloured, conventional polyamide 6.6 cable tie (width 7.7 mm) already showed significant material degradation caused by the UV radiation after 200 hours in the test chamber. The loop tensile strength of this non-UV-stabilised material sank to below half its initial value. In contrast to this, it is apparent that the Q50L-W and T80R-W, made of UV-stabilised polyamide 6.6, as well as the GL250, made of polyamide 11, show virtually no effects of UV weathering
