NEW UV Tests on Highline Webbing


Effects of UV on breaking strength of polyamide and polyester highline webbing Members of the ISA Safety Commission have performed comparative two year degradation tests of some commonly used webbing materials used in  highlining . These tests were performed at extreme weather conditions in a high alpine environment to evaluate the highline webbing safety standard ISA:41 and to provide further data for evaluating highline webbing lifetime around the globe. The high-altitude Jungfraujoch research station offers a perfect venue for installing an array of frames with different webbing samples for a long-term, combined weathering and solar radiation study.
