The standard has allowed lots of festival organisers and professional riggers to better negotiate access and safety with insurance companies, landowners and officials from a local to a national level.
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.
On one hand this standard provides a framework for highliners as well as slackline manufacturers to understand what components are where and how they interact. On the other hand, it also provides a legal framework for highlines to be categorized as temporary installations and even permarigs with the prober maintenance checklists in place.
In addition to that, it also defines the forces that are acting upon the webbing, anchors and the highliner. In essence, it allows our partners, testing laboratories and technical engineers to communicate more effectively.
