On May 7, 2021, a technical standard ČSN 83 2610 Knots – Terminology was published in the Czech Republic.

The purpose of this technical standard is to define and unify the terminology, terms and definitions concerning the most common knots used for work at heights (rope access), mountaineering, military climbing, rope activities at heights of police units, tree climbing, rescue and caving. It does not provide a complete or exhaustive list of all knots used in these activities.

The terminology is based primarily on the principle and function of the knots tied, the author of the knot, the usage of the knot, or according to the established and conventional name of the knot.

ČSN 83 2610 contains the 46 most commonly used knots (4 simple basic knots, 15 anchor knots, 6 bend knots, 7 “anomalous” knots, 4 handling knots, 7 self-clamping ascending knots, 3 self-clamping locking knots) and several others knots are placed as examples in Terms and definitions.
The benefit of the standard is not only the unification of knot names, but also their “legalization”. Especially in occupational health and safety (related to rope access), it is common for a safety supervisor does not allow to use the knot, simply because he does not know it. Thus, with reference to the standard ČSN 83 2610, the rope access technician can argue: that this knot is approved by technical standard for the given use.
