Hieronder een filmpje (helaas geschoten met digi fotocam) van 3 verschillende release systemen.

Resultaten varieren tussen 4 en 30 kilo die nodig is om je kite te releasen.

Check altijd je QR systeem, ook onder belasting. Kan het verschil tussen leven en dood maken!

Handig zo een machine maar denk dat je het nooit zo goed kan testen als in de werkelijkheid, op het water dus!

Franse norm:

For the 2010 bars, we insisted on applying the French norm, just like last year.

This means that a public institution must test various requirements to two systems of the bar under preset conditions:

- The quick release system of the bar
- The quick release that separates the rider completely from the kite (safety leash)

Both safety systems are tested in various media, the release force must not exceed 100N (9.8Kg). The actual release process of both systems must not exceed 0.5sec.

The transition from riding position to release (reaching for the QR loop or safety leash from riding position with both hands on the bar) must not exceed 2sec.

Other requirements: The grips of the release system must be red and the direction of release must be indicated. The release grips must be easy to reach.

Furthermore, the QR loop must resist a load of 300kg without deformation and without losing functionality. The same applies to the safety leash with a load of 150kg.
