INTRODUCTION
The goal of these test methods is to provide reliable and repeatable methods for the evaluation of
motorized treadmills. Users of the equipment must recognize that conformance to a standard will not
necessarily prevent injuries. Like other physical activities, exercise involving a treadmill involves a
risk of injury, particularly if the equipment is not maintained or used properly.
The equipment user must recognize, however, that a standard alone will not necessarily prevent
injuries.Likeotherphysicalactivities,exerciseinvolvingfitnessequipmentinvolvestheriskofinjury,
particularly if the equipment is used improperly or not properly maintained. In addition, users with
physical limitations should seek medical advice or instruction from the fitness facility, or both, prior
to using this equipment. Certain physical conditions or limitations may preclude some persons from
using this equipment as intended by the manufacturer, and using this equipment may increase the risk
of injury.

Designation: F2106 − 12 F2106 − 18 An American National Standard
Standard Test Methods for
Evaluating Design and Performance Characteristics of
Motorized Treadmills
This standard is issued under the fixed designation F2106; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
The goal of these test methods is to provide reliable and repeatable methods for the evaluation of
motorized treadmills. Users of the equipment must recognize that conformance to a standard will not
necessarily prevent injuries. Like other physical activities, exercise involving a treadmill involves a
risk of injury, particularly if the equipment is not maintained or used properly.
The equipment user must recognize, however, that a standard alone will not necessarily prevent
injuries. Like other physical activities, exercise involving fitness equipment involves the risk of injury,
particularly if the equipment is used improperly or not properly maintained. In addition, users with
physical limitations should seek medical advice or instruction from the fitness facility, or both, prior
to using this equipment. Certain physical conditions or limitations may preclude some persons from
using this equipment as intended by the manufacturer, and using this equipment may increase the risk
of injury.

6.3 Endurance—Endurance Loading—These tests are intended to confirm the endurance of the main components of the
treadmill.
6.3.1 Mechanical Frame Endurance—The stationary moving surface, frame, and structural components of the treadmill are
subjected to a repeated load equal to 1.5 times the maximum user weight as specified by the manufacturer.
6.3.1.1 Apparatus and Set Up—A pneumatic cylinder or other appropriate load application device shall be fixtured to apply load
to the moving surface at the centerline of the treadmill 33 % of the length of the usable moving surface rearward from the front
of the usable moving surface. A 30 by 30 cm (12(11.8 by 1211.8 in.) load application area shall be used for the test. Timing controls
must be supplied to regulate the load application frequency. Provide appropriate instrumentation to assure that the load is consistent
throughout the test duration.
6.3.1.2 Calibration—Verify that the load and frequency measuring equipment is properly calibrated and that the load accuracy
is within 65 % of the applied load and that the frequency measurement is accurate to within 60.2 Hz.
6.3.1.3 Procedure—Elevate the treadmill to the incline that will provide the most stress to the frame and incline system
components and position the treadmill under the load application device. No power shall be connected to the treadmill. Block the
treadmill into position so that the vibrations created by the test do not cause it to move on the floor. Apply power to the load
application system. Adjust the applied load to 1.5 times maximum user weight 65 % at a frequency of 0.5 to 2 Hz. Assure that
the moving surface rebounds completely prior to the next cycle. Verify that the counter is recording the number of cycles. Inspect
the treadmill and test apparatus approximately every 250 000 cycles or as needed to insureensure that the test is functioning
properly. If the design of the treadmill is such that keeping the moving surface stationary for the duration of the test would
abnormally stress the moving surface (that is, a treadmill that employs moving slats rather than a conventional belt and deck), the
moving surface may be repositioned periodically during the test.
6.3.1.4 Pass/Fail Criteria—Upon completion of the test, remove the test unit from the fixture and confirm normal operation of
all functions. The treadmill must meet life requirements per classification of use per subsection 4.44.3 of Specification F2115. The
unit must not show structural cracks or other indications of impending failure.
6.3.1.5 Precision and Bias—No information is presented about either the precision or bias of this test 9.3.1for evaluating frame
endurance since the test result is non-quantitative.
6.3.2 Treadmill Switch and Switch Actuation Mechanism Endurance—Stop, Pause or End functions (see Note 1).
NOTE 1—If several means of stopping exist—for example, Stop switch and Pause switch—each means must be separately tested only if the actuator
types are different.
6.3.2.1 Apparatus and Set Up—Provide a mechanism to repeatedly activate the switch of interest at a rate not to exceed 2 Hz.
and to accumulate a count of actuations. Activation force for testing shall be 1.5 times 1.5× 6 10 % the minimum actuating force
for the particular switch. For push switches, the activating mechanism can be a simulated finger mounted to an appropriate
pneumatic cylinder operating parallel to the line of action of the switch, a test system designed specifically for switch testing
(having an air cylinder plunger with a rounded simulated finger 0.675 diameter, 45 durometer rubber, SF-45), or other appropriate
actuating means. For non-returning switches, a mechanism must be provided to pull out the switch between actuations, with a force
equal to 1.5 times 1.5× 6 10 % the minimum activating force. For lanyard-type, pull-off mechanisms, the switch can be tested as
outlined above without the lanyard attached. If this method is employed, a separate lanyard strength test must be conducted by
applying a load equal to 5 times the maximum activation force of the switch on the lanyard. A means of automatically sensing
activation (for example, sensing a “beep” from the control panel internal electronics) will allow monitoring each activation
response.
6.3.2.2 Calibration—Verify that the load application system applies 1.5 times 6 10 % of the minimum activation force for the
switch to be tested. Using appropriate instrumentation, set the timing of the activator to 0.1 to 0.2 s “on” time and the repeat rate
as desired but not over 2 Hz. Verify activation counter operation for at least 100 cycles. If a lanyard pull is required, the pull force
must guarantee activation.
6.3.2.3 Procedure—Actuate the switch being tested with the load application system and confirm that the force applied causes
the switch to function. The function of the switch shall be confirmed on every actuation of the switch via a circuit that actuates
a counter. A manual check must be made of switch function before and after the full test sequence, and during the automated
F2106 − 18
sequence, some activation-confirming feedback must be observable for each activation. As an alternate to this procedure, if the
switch is installed according to the switch manufacturer’s recommendations, the switch manufacturer’s testing may be used.

to the moving surface as described in 9.3.1.16.3.1.1. The treadmill is to be supported only at points specifically intended for support
during use. Apply the load for 5 to 15 s. Remove the load. Then apply vertical force of 2 times 2× the maximum user weight for

of the rear roller. Apply the 180 N (40 lb) load horizontally to the topmost handrail in the direction that could cause folding. Verify
that the handlebars do not fold down when this load is applied. For treadmills where the deck and moving surface fold up for
storage verify that the deck and moving surface do not reach the balance point before the latching mechanism engages. Visually
verify that a locking mechanism is present to secure the deck and moving surface in the storage position. For treadmills where the
handrails and upright fold up for use verify that the handrails and uprights do not reach their balance point before the locking
mechanism engages. Visually verify the presence of a locking mechanism to secure the handrails and uprights in the use position.

surfaces. If the test is conducted at an ambient temperature of other than 25°C (77°F), the temperatures are to be corrected to that
temperature.

pin, or other means to provide limited fixed positions, and that do not actually provide the energy to adjust the incline, are excluded
from this test.

accuracy of 2.5 mm/s (0.1 in./s) will be necessary for the velocity measurements. The velocity will be determined by dividing the
displacement by the time required for movement. As an alternate, an instrument that directly measures vertical velocity having the
accuracy stated above may be used. The instrumentation is to be fixtured to measure the relative velocity of any pinch or shear
points that occur during actuation of the incline system. A method of applying maximum specified user weight that is independent
of angle of inclination must be provided.
