... Council Canada started a TPO Weathering Farm Project in 2000 to examine weathering characteristics of TPO roof membranes by exposing them to various weather conditions of four distinctly different climatic regions in the Western United State s. The goal was to provide technical and performance information...

... for Thermoplastic Polyolefin Based Sheet Roofing,” Annual Book of ASTM Standards , Vol. 04.04, ASTM International, West Conshohocken, PA, 2008, www.astm.org, which sets a minimum threshold for accelerated weathering performance. To be ASTM D6878 compliant, a TPO membrane shall not show any visual micro-cracking...

... on the results of the experiment, it was concluded that the wear testing method is a good indicator of the weathering degree. It was shown that the imposed weathering process decreases the abrasion resistance of the rock and increases its micro-fragmentation ability. 26 11 2008 29 06 2009 13 08...

..., the RILEM TC139-DBS “Durability of Building Sealants” was created to develop new and more adapted testing. The testing proposed by this comity, was a combination of accelerated weathering (humidity and UV) combined with thermo-mechanical cycling. This study compares the durability of silicone sealants...
