All Mammut slings are tested to the applicable standards and must have a minimum strength of 22kN.
Like cord, webbing has a very low elongation and is therefore designed for static and semi-static loads, for absorbing strength rather than energy. Slings and cords are therefore used mainly as intermediate belays. Due to the lack of dynamics of slings, it is important to avoid climbing higher than a belay when attached to a sling. If the event of a fall, the sling could tear, since, unlike alpine rope, it cannot absorb energy through its dynamics.
If a sling is knotted, this significantly reduces its breaking force. See also:
