This document describes modelling of various tightening systems like fixtured system, handheld system, intelligent tool etc.

In this version of the specification, tightening system consists of models for assets, results, basic events.

Assets provide a way for an external system to understand the physical representation of the system and is a vital “skeleton” for many other core models and functions, such as for example condition monitoring.

Result reporting is the most important and common use case for communication with a tightening system.
