1 Scope
EN 957-6 specifies safety requirements and test methods for treadmills in addition to the general safety
requirements and test methods of EN 957-1 and shall be read in conjunction with it.
EN 957-6 is applicable to power-driven as well as to non-power/manually driven training equipment type
treadmills (hereafter referred to as treadmills) with the classes S, H and I and classes A, B and C regarding
accuracy.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 957-1:2005 and the following apply.
3.1
treadmill
training equipment with a running surface on which walking or running activity takes place, where the feet are
free to leave the running surface
3.2
length of the running surface
usable length of the running surface
NOTE 1 See l in Figure 2.
NOTE 2 Figure 1 is intended only to give examples and to illustrate the names of the components.
3.3
width of the running surface
usable width of the running surface excluding rear roller guards
NOTE See b in Figure 2.
3.4
front handlebar
frontally located bar provided for partially supporting the user's weight with the user's arm(s) and enhancing
stability whilst exercising and to assist in emergency dismounts
EXAMPLE At low speed and high inclines.
3.5
side handrail
rail(s) located at the sides of the running surface provided for partially supporting the users weight with the
user's arm(s) and enhancing stability whilst exercising and to assist in emergency dismounts
3.6
foot rail
area beside the running surface intended for the user to stand on when mounting, dismounting or during a
pause in the exercise
3.7
emergency dismount
act of the user quickly interrupting the exercise by getting off the running surface
NOTE Emergency dismount can be done e.g. by grabbing the front handlebar or both side handrails and jumping
with both feet on the foot rails.
3.8
heart rate control mode

5 Safety requirements
5.1 Squeeze and shear points within the accessible area
All parts of treadmills, including any folding mechanism, shall be in accordance with EN 957-1:2005, 5.2.3 in
folded position, during folding and in usable position. For folding treadmills the lock for securing the equipment
is excluded.
Where the inclination can be changed during operation thus causing the distance between any part of the
equipment and the floor to become smaller than 60 mm the speed of inclination shall not exceed 1°/s and the
user shall be able to stop this movement.
5.2 Transmission elements and rotating parts
Pull-in points between the running surface and fixed or moving parts of the treadmills or the floor shall be
avoided.
An identifiable feature showing the maximum allowed lateral position of the running surface shall be provided
on the treadmill [see 8 f)].
a
NOTE See in Figure 2.
When tested in accordance with 6.1 it shall not be possible that the test finger becomes trapped between the
rear roller guard and the running surface. With the running surface centred, the rear roller guard shall overlap
the edges of the running surfaces by min. 10 mm and max. 40 mm (see Figure 3).
The vertical gap between the running surface and the rear roller guard or overlapping foot rails shall not be
more than 9,5 mm.
Dimensions in millimetres
