6.1 General

The equipment shall comply with the safety requirements and/or protective measures of this clause. In

addition, the equipment shall be designed according to the principles of EN ISO 12100 for relevant but not

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 guards that have

to be removed for maintenance, adjustment or inspection shall be retained by fasteners that are retained in

the guard or machine when the guard is removed."

EN 957-6:2010+A1:2014 (E)
6.2 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 !useable" 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.
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.

Identifiable feature(s) indicating the acceptable lateral position(s) of the running surface shall be provided on

the treadmill [see in Figure 2 and Clause 10 g)]."
!(deleted text)"

When tested in accordance with !7.1," 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
Figure 3 — Example of a rear roller guard (min. 10 mm and max. 40 mm)
6.4 Temperature rise

When tested in accordance with !7.2", accessible parts of the treadmill shall not have a temperature

greater than 65 °C.
6.5 Safety stop (emergency stop)"
6.5.1 General

All power driven treadmills shall be equipped with a safety stop switch, which shall include a push-button

operated switch and/or a pull-cord operated switch.

The push-button type or pull cord safety stop actuator shall be in a reachable position in front of the user and

in an area of ± 180 mm parallel to the centreline of the running surface.
---------------------- Page: 15 ----------------------
SIST EN 957-6:2011+A1:2014
EN 957-6:2010+A1:2014 (E)
!Test in accordance with 7.3."

If the push-button type safety stop actuator is outside this area it shall be duplicated on the opposite side

except when a pull-cord actuator is provided.
6.5.2 Characteristics

Operating the safety stop shall result in the machine cutting off the main power of the motor and the inclination

system without relying on any software functions.

The contacts of manually operated safety stop devices shall ensure positive opening. The achievement of

contacts separation shall be the direct result of a specified movement of the switch actuator through non

resilient members. Emergency stop relays or manually reset fail-safe relays may be used.

It shall not be possible to restore the circuit until the actuator of the safety stop device has been manually

reset. After restoring !the circuit," the equipment shall restart with standstill and the incline shall stay the

same or reset according to !6.2". Where several safety stop devices are provided, the circuit shall not be

restored until all actuators previously operated have been reset.
Test in accordance with !7.3".
6.5.3 Actuator(s)

!Actuators of safety stop devices shall be coloured RED. The actuator of a push-button operated switch

shall be of the palm or mushroom head type and shall have a yellow background."

The background around the actuator shall be at least 5 mm wider than the actuator itself on all sides.

Pull-cord safety stop actuators shall release with a maximum force of 50 % of the force required to release the

attachment device when attached to the user according to the manufacturers' recommendation.

The actuator cord shall have a suitable length so that the actuator releases at a position not more than 70 %

of the length of the running surface.
Test in accordance with !7.4".
6.6 Immobilization method

For power driven treadmills there shall be an immobilization method for the treadmill to prevent uncontrolled

usage of third parties. This method shall be explained in the instructions for use.

Test in accordance with !7.5".
