e) running from the surface of the vertical height of 800mm ~ 950mm.

Measured from the center two side bars, the maximum spacing is 900mm.

By 6.8 when tested side armrest/handle before permanent deformation should not exceed 3%. If the treadmill has both front and side handrails handle it

We should also meet this requirement.

5.9 foot platform

Treadmills should be equipped with a foot platform, see Figure 1.

After removing the cylinder cover, the foot platform and running the length of the surface should be the same, and a minimum width of 80mm.

Foot platform should have at least 400mm × 70mm non-slip surface, when the test according to ISO 5904, the coefficient of friction of not less than 0.5.

When the test by 6.9, permanent deformation of the foot platform should not exceed 3%.

Side armrest can be connected to the foot platforms.

Note. This article does not apply to non-slope or flywheels human treadmill.
