This specification covers the establishment of parameters for the design and manufacture of motorized treadmills. The treadmill shall be stable during intended use. Its edges in accessible areas shall be free of burrs and sharp edges and its corners in accessible areas shall be radiused or chamfered. Its tube ends in the exposed accessible areas shall be closed off either by other components or plugs, caps, or covers. In addition, the design of rotating parts shall avoid shear, pinch, or catch points by guarding, shielding, spacing, or other appropriate means. To reduce the risk of finger entrapment, the rear roller of the treadmill shall be designed or guarded. The guard or design shall function through the full range of inclination possible and through the full range of belt tension adjustment. Foot rails and handrails shall be present in all treadmills to facilitate user mounting and dismounting. Its moving surface shall be constructed to minimize foot slippage. The control panel for the operation of the treadmill shall be readily accessible by the user. The controls for a motorized treadmill shall incorporate a prominently labeled and user accessible stop switch. The stop switch causes the moving surface to decelerate and stop and stops the motion of any power-driven incline system. Stop mechanisms may include a push-button stop switch, a pull cord stop switch, an infrared beam switch, or other suitable means. Adequate warnings alerting users, third parties, and service personnel to hazards associated with treadmills shall be provided.

1.1 This specification covers the establishment of parameters for the design and manufacture of motorized treadmills.

1.2 It is intent of this specification to specify products for use by individuals age 13 and above.

1.3 This standard is to be used in conjunction with Specification F2276, Test Methods F2571, and Test Methods F2106.

1.4 This standard takes precedence over Specification F2276 and Test Methods F2571 in areas that are specific to motorized treadmills.

1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
