BS ISO 20957-6:2021 pdf download – Stationary training equipment Part 6: Treadmills, additional specific safety requirements and test methods
This document specifies safety requirements and test methods for treadmills in addition to the generalsafety requirements and test methods of ISO 20957-1. It is intended that this document is appliedtogether with ISo 20957-1.
This document deals with significant hazards, hazardous situations and events relevant to stationarytraining equipment used as intended and under the conditions of misuse foreseeable by themanufacturer (see Clause 4).
This document is applicable to power-driven as well as to non-power/manually driven trainingequipment type treadmills (hereafter referred to as treadmills) with the classes S,H and l and classes A,B and C regarding accuracy.
This document is not applicable to treadmills which are manufactured before it publication.

3Terms and definitions
Forthe purposes of this document, the terms and definitionsgiven in ISO 20957-1and the following apply.
treadmill designed with some components that can be moved to allow a more compact non-useablestorage position
4 List of significant hazards
Table 1 shows the significant hazards, hazardous situations and events, as far as they are dealt with inthis document, identified by risk assessment as significant for this type of equipment and which requireaction to eliminate or reduce the risk.
For a particular treadmill, a risk assessment should be carried out by the manufacturer to identify anyadditional significant hazards so that suitable protective measures can be taken. Additional hazardsare outside the scope of this standard.
For identification and evaluation of hazards,ISO 12100 shall apply.
ISO 20957-1:2013, Clause 4 shall apply.
6 Safety requirements and/or protective measures6.1General
The equipment shall conform with the safety requirements and/or protective measures of this clause.ln addition, the equipment shall be designed according to the principles of ISo 12100 for relevant butnot significant hazards, which are not dealt with by this document.
Fixed guards shall be fixed by systems that can be opened or removed only with tools.Fixed guardsthat have to be removed for maintenance, adjustment or inspection shall be retained by fasteners thatare retained in the guard or machine when the guard is removed.
6.2Squeeze and shear points within the accessible area
All parts of treadmills, including any folding mechanism, shall be in accordance with ISO 20957-1:2013,5.3.3 and 5.3.4 in folded position, during folding and in useable position.For folding treadmills the lockfor securing the equipment is excluded.
Where the inclination can be changed during operation thus causing the distance between any part ofthe equipment and the floor to become smaller than 60 mm, the speed of inclination shall not exceed1/s and the user shall be able to stop this movement.
6.3 Transmission elements and rotating parts
Drawing-in shall be prevented at all points between the running surface and fixed or moving parts of the treadmills or the floor.
