ISA:21 Highline Systems What is a highline? The ISA:21 Highline Systems Standard is a formal engineering definition and description of what a highline is and what the various components it consists of are. In addition to that, it also defines the forces that are acting upon the webbing, anchors and the highliner. In essence, it is a lot of fancy words, but it allows our partners and testing laboratories to communicate more effectively. Download Highline System Standard 21:2019 On one hand this standard provides a framework for highliners as well as slackline [...]
Every Great idea starts somewhere…. For the first time, the ISA is organizing a science prize. Our goal is to promote scientific research which benefits the slackline community. Please check out the following notes before you begin your project. It´s short and painless. We promise. Rules to keep in mind: In order for your study to get accepted it must follow the systematic investigation of scientific theories and hypotheses, which are relevant to slacklining and further fulfills the following criteria: It must be written in English or German. All submissions (not only winners) must be allowed [...]
Webbing slippage warning in Weblocks. We have identified the mechanism responsible for webbing slippage in webbing lockers (weblocks). During a test on a hydraulic cyclic testing machine, we found webbing to move through the weblock with every stretch and release cycle. We observed this micro-slippage of the webbing within the weblock. Read Full Report - Webbing slippage warning in weblocks The webbing was installed in single wrap without a tie-off so we could witness webbing slippage, webbing tailwalk, and a complete failure of the webbing locking mechanism first hand. The Solution [...]
From the 11.09.-13.09.2017 (Monday-Wednesday) on Le Molèson, Gruyère in Switzerland, the International Slackline Association (ISA) presents the first exchange for slackline manufacturers and people interested in advanced slackline safety. The Safety Commission welcomes manufacturer, engineer, technician and/or working in other related fields interested in advanced slackline safety, to this Meeting and Workshop. And yes, Gruyère is where the famous cheese and fondue is from! The Safety Commisson of the ISA is the organizing committee. The local host is ISA Member Swiss Slackline. For more information, the preliminary programm and the inscription, click here. The ISA Safety Event takes place right before [...]
The Longline Recommendations document that was published this summer is now available in Portuguese. German and English versions were previously online. Thanks to our volunteer translators and proofreaders for their efforts. Take a look!
