3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 normal operation, n—the operation of the selectorized strength equipment as defined by the manufacturer.
4. Significance and Use
4.1 The purpose of these test methods is to provide valid and repeatable test methods for the evaluation of selectorized strength
equipment assembled and maintained according to the manufacturer’s specifications. Use of these test methods in conjunction with
Specification F2216 is intended to maximize the reliability of selectorized strength equipment design and reduce the risk of serious
injury resulting from design deficiencies.
5. Sample Preparation
5.1 Assemble and adjust the selectorized strength equipment according to the manufacturer’s instructions. Remove upholstered
pads from the sample. On machines that are fully assembled, verify according to the manufacturer’s instructions that all
components are functioning and that they have been adjusted and aligned properly. Unless otherwise stated, the machine must pass
the tests without adjustment from this initial condition. Selectorized strength equipment shall be provided with the largest weight
stack offered by the manufacturer for the model to be tested.
5.2 The individual test methods will describe any variations or modifications that are required to the test sample.
6. Test Methods and Procedures
6.1 Stability:
6.1.1 Selectorized strength equipment shall be tested with and without the simulated user load in the orientation that is most
obviously unstable. If the orientation that is most obviously unstable is not clear, it may be necessary to test several orientations.
6.1.2 Apparatus and Set-Up—Refer to Fig. 1. Place sample on a non-skid surface inclined at 10° in the orientation that is least
stable. The sample shall rest on the supporting surface without anchoring unless the installation instructions for the machine require
that the sample be anchored to the floor. If this is the case, then anchor the specimen per the manufacturer’s recommendations.
Determine how the user is placed on the machine to perform the exercise (that is, seating, standing, or prone) and then determine
how the user’s body weight is distributed onto the user support surfaces. For the simulated use test, a method of applying a steady
state load equal to 100 kg (220 lb) simulating the user’s weight and its distribution in the vertical direction at the point(s) of user
contact must be provided. As an example, for a seated user, the user support surface shall be adjusted to the uppermost position
(if adjustable) and the center of gravity of the 100 kg (220 lb) load shall be positioned approximately 300 mm (12 in.) above the
user support surface. Possible methods of providing this load include, but are not limited to, pneumatic cylinder(s) or dead weights.
6.1.3 Calibration—Using an angle measuring instrument accurate to within 0.1°, verify the non-skid surface is 10 6 0.5°.
Calibrate the load measurement apparatus to confirm accuracy to within 620 N (4.5 lb) over entire 981 N (220 lb) range.

FIG. 1 Tilt Test
6.1.4 Procedure—Test the sample as follows:
6.1.4.1 With the sample machine (no user load applied) positioned on the tilt surface, verify that the sample does not tip over
with the resistance means in the rest position.
6.1.4.2 Using the aforementioned load apparatus, distribute a vertical load equal to 100 kg (220 lb) 6 5 % in a non-impact
manner to the specimen where the user contacts the machine during normal operation. (If only a portion of the user’s body is
supported by the machine during operation, the 100 kg (220 lb) simulated user weight shall be reduced by the appropriate amount.)
Raise and support the lifting arms and weight stack to simulate the furthest point in the range of travel as encountered during
normal operation of the machine by a user of 1.8 m (74 in.) stature. Verify that the sample does not tip over.
6.1.4.3 Repeat 6.1.4.1 and 6.1.4.2 with the sample oriented in any other directions of potential instability.
6.1.5 Pass/Fail Criteria—In none of the above test conditions shall the sample tip over.
6.1.6 Precision and Bias—No information is presented about either the precision or bias of test 6.1 for measuring stability since
the test result is non-quantitative.
6.2 Weight Stack Travel:
6.2.1 This test is a visual inspection of the sample to ensure that the weight stack travels freely along its guide means and returns
to its initial position after the displacing force has been removed.
6.2.2 Apparatus and Set Up—The sample shall be set up as described in 5.1.
6.2.3 Calibration—No calibration required. Visual inspection only.
6.2.4 Procedure—Move the lifting arm through its range of travel and verify that the weight stack moves along a guide means
in a controlled manner and returns to its initial position as the lifting arm is returned to its initial rest position.
6.2.5 Pass/Fail Criteria—The weight stack must begin and end the test in the same rest position and must not move unless it
is displaced intentionally by a lifting force applied to the lifting arm.
6.2.6 Precision and Bias—No information is presented about either the precision or bias of test in 6.2 for evaluating weight
stack travel since the test result is non-quantitative.
6.3 Weight Stack Selector Pin Retention:
6.3.1 This test is a visual and physical inspection of the weight stack selector pin to ensure that the design features a retention
device and that it functions properly.
F2277 − 17a

of the function of the weight stack selector pin from the manufacturer.
6.3.3 Calibration—No calibration required. Visual and function inspection only.
6.3.4 Procedure—Inspect the weight stack selector pin and ensure that it features a retention device that will not allow the pin
to be removed from the weight stack unless it is intentionally removed. Examples of retention devices include, but are not limited
to, spring activated detent balls or a physical deformation of the pin and comparable retention zone on the weight plate. The
operation of the retention system shall be self-evident. Insert the weight stack selector pin into a weight on the weight stack and
verify that the retention mechanism functions properly.
6.3.5 Pass/Fail Criteria—Weight stack selector pins that do not have a retention means shall fail this test. Retention mechanisms
that do not function according to the instructions provided by the manufacturer shall fail this test.
6.3.6 Precision and Bias—No information is presented about either the precision or bias of test in 6.3 for evaluating weight
stack selector pin design and function since the test result is non-quantitative.
6.4 Entrance/Exit from Machine:
6.4.1 This test is a visual and physical inspection of the machine to determine whether or not an assist means is required and
then ensure that the design functions properly.
6.4.2 Apparatus and Set Up—The sample shall be set up as described in 5.1. Reinstall the upholstered pads for this test. Obtain
instructions or a descriptive explanation of the function of the assist mechanism(s) used on the sample from the manufacturer.
6.4.3 Calibration—No calibration required. Visual and function inspection only.
6.4.4 Procedure—Adjust the machine for the evaluator’s size according to the manufacturer’s instructions. The evaluator shall
enter the machine and attempt to get into the exercise start position as described in the operation instructions provided by the
manufacturer. The evaluator shall be able to get into and back out of the starting position with relative ease. If the lifting or user
means cannot be reached by the evaluator or if the evaluator cannot get into the starting position easily, then further adjustment
of the machine may be required. If this is not the case (the machine is properly adjusted per the operation instructions for the given
body size of the evaluator), then an assist means that moves the lifting or user means into the direction of lifting stroke must be
provided.
6.4.4.1 If an assist means is provided, then operate the mechanism and ensure that it performs as described in the operation
instructions. Upon actuation of the assist means, the lifting or user means shall move into the direction of machine motion allowing
the user to get into the loaded exercise start position. Upon completion of the exercise and return of the lifting or user means to
the rest position, actuation of the assist means shall stop the lifting or user means prior to reaching the unloaded rest position,
thereby allowing the user to exit from the loaded use position.
6.4.5 Pass/Fail Criteria—Machines that do not allow the user to enter or exit the machine easily shall fail the test. Assist
mechanisms that do not function according to the instructions provided by the manufacturer shall fail test. Assist mechanisms that
do not stop the lifting or user means far enough into the lifting stroke to allow the user to control and/or stop the final return travel
of the lifting or user means shall fail the test.
6.4.6 Precision and Bias—No information is presented about either the precision or bias of test in 6.4 for evaluating assist
mechanism design and function since the test result is non-quantitative.
6.5 Belt or Rope System Design and Load Testing:
6.5.1 This test is a visual, physical, and functional inspection of the cables, belts, or ropes and their end fittings and attachment
means used on the sample to route the load from the resistance means to the user means to ensure that the design functions as
intended and meets the parameters of Specification F2216.
6.5.2 Apparatus and Set Up—The sample shall be set up as described in 5.1. Obtain instructions or a descriptive explanation
of the function of the specimen from the manufacturer. Three cable, belt, or rope specimens measuring 150 mm (5.9 in.) replicating
the system installed on sample including their attachment means shall be provided for a separate loading test.
6.5.3 Calibration—Calibrate the load measurement apparatus to confirm accuracy to within 650 N (611 lb).
6.5.4 Procedure:
6.5.4.1 Design Evaluation—Select the minimum resistance level for the sample. Cycle the machine through several complete
repetitions while observing the rope or belt attachment points. Ensure that all end fittings and attachments move freely with the
lifting and resistance means and that the rope or belt does not cyclically bend or flex around these components by more than a total
amount of 10°, as shown in Fig. 2.
6.5.4.2 Load Testing—Obtain and record from the manufacturer the maximum load amount that the belt or rope system is
subjected to during operation of the sample machine through its recommended range of motion. This should take into account any
multiplying effects designed into the system to increase the resistance to the user. Secure a 150 mm (5.9 in.) specimen at its end
fittings or attachments points into a tensile loading apparatus capable of loading the specimen with 6 times the aforementioned
maximum load. The apparatus shall be capable of recording the maximum load attained during the test. Apply a load to the system
equal to 6 times the maximum load stated above. Maintain this load for 5 min. If the system fails before attaining the 6 times load,
record the load attained at failure. If the system attains the load but fails before the 5 min test period has expired, record the load
and the amount of time at that load. Repeat the test for each of the remaining specimens.
6.5.5 Pass/Fail Criteria:
F2277 − 17a
FIG. 2 Cable and Fitting Flexure
6.5.5.1 Design—If the end fitting or termination point on a belt or rope cyclically flexes through an arc of more than 10° during
normal or intended use as defined by the manufacturer in either a combined or unidirectional amount then the cable, belt, or rope
system shall fail the test.
6.5.5.2 Load Testing—If the belt or rope system fails to attain 6 times the maximum load and fails to maintain that load for 5
min then the system shall fail the test.
6.5.6 Precision and Bias—No information is presented about either the precision or bias of test in 6.5 for evaluating belt or rope
system design since the test result is non-quantitative.
6.6 Pulley and Pulley Enclosure Design:
6.6.1 This test is a visual, physical, and functional inspection of the pulleys used on the sample to rout the load from the
resistance means to the user means to insure that the design functions as intended and meets the parameters of Specification F2216.
This test also verifies that the pulley enclosures prevent the ropes or belts from being inadvertently disengaged from the pulleys.
6.6.2 Apparatus and Set Up—The sample shall be set up as described in 5.1. Obtain instructions or a descriptive explanation
of the function of the specimen from the manufacturer. A method of applying a force of 20 N (4.5 lb) perpendicularly to the rope
or belt shall be provided.
6.6.3 Calibration—Calibrate the load measurement apparatus to confirm accuracy to within 60.5 N (0.1 lb). Verify that the
measuring device is accurate to 1 mm (0.04 in.).
6.6.4 Procedure—Inspect and measure the pulley and verify that it falls within the parameters specified in Specification F2216
for the size wire rope being used on the machine. If the machine is belt driven, verify that the pulley is designed to prevent
disengagement. Appropriate means would include convex or concave profile or retainment edges on each side of the pulley.
6.6.4.1 Examine the enclosures for the pulleys. Grasp the rope or belt as it exits/enters the enclosure and apply a pulling force
of 20 N (4.5 lb) 90° to the direction of travel. The cable or belt shall not come off of the pulley. Repeat this process at other pulley
locations on the machine.
6.6.4.2 Select the full resistance level of the sample and move the lifting means through one or more cycles at a slow and
controlled rate of motion. The pulleys shall rotate as the lifting means is cycled.
6.6.5 Pass/Fail Criteria—Pulleys with dimensions falling outside of those specified in Specification F2216 shall fail test. Belt
pulleys failing to feature a retention design shall fail the test. Enclosures that allow for disengagement of the cable or belt shall
fail the test. Pulleys that do not rotate under full loading shall fail this test.
6.6.6 Precision and Bias—No information is presented about either the precision or bias of test in 6.6 for evaluating pulley and
pulley enclosure design and function since the test result is non-quantitative.

FIG. 3 Probe Specifications
6.7 Entrapment Testing:
6.7.1 This test is to evaluate the risk of injury to the user or to a third party due to inadvertent contact with a moving mechanical
part and a fixed component of the machine. The results of this test determine the adequacy of spacing between components.
Methodology entails insertion of a sized probe into the entrapment areas discussed in Specification F2216. It has been assumed
that contact in these areas is inadvertent and therefore the test will be perpendicular and through the area in question and not
articulated into all possible areas around the potential hazard.
6.7.2 Apparatus and Set Up—The sample shall be set up as described in 5.1 with the upholstered pads reinstalled. This test
requires a probe as specified in Fig. 3.
6.7.3 This test also requires sized probes of 9.5 mm (0.38 in.) and 25 mm (0.98 in.) for areas most susceptible to finger injury
and 60 mm (2.36 in.) for all other areas. Verify that all guards are properly positioned and secured. An apparatus capable of
measuring 4.4 N (1 lb) of pulling force shall be provided.
6.7.4 Calibration—Calibrate the load measurement apparatus to confirm accuracy to within 60.5 N (0.1 lb). Verify that the
probe conforms to the dimensions shown in Fig. 3. Verify that the 9.5 mm (0.37 in.) sized probe is no less than the stated size and
that the other sized probes are no greater than their stated sizes.
6.7.5 Procedure—Refer to Specification F2216 while conducting this test. The evaluator shall place himself/herself on the
sample in the operational position and determine and note regions of the sample that are to be evaluated. Areas of concern that
are 1800 mm (71 in.) or more above the floor are exempt from this requirement and do not need to be examined further. Areas
that are blocked by the user of the equipment throughout the range of motion are also exempt from further examination. The
evaluator shall pay attention to areas outside their field of view and areas outside their reach as discussed in Specification F2216.
The evaluator shall determine, for the area of concern, the portion of the body most likely to be injured and then use the appropriate
probe. Insert the probe perpendicular to this area and cycle the machine through one stroke with the minimum resistance selected
to verify probe entrapment. Repeat with the full amount of resistance for the area of concern. Pay close attention to the deflection
of the machine and its components as this deflection may create new areas of concern. If the probe becomes entrapped, apply a
pulling force to remove the probe. Record the force required to remove the probe.
6.7.6 Pass/Fail Criteria—The probe shall not become entrapped in any mechanical hazard. Entrapment is defined to have
occurred if the force to pull out the probe is greater than 4.4 N (1 lb).
6.7.7 Precision and Bias—No information is presented about either the precision or bias of test in 6.7 for evaluating entrapment
points outside of the field of view of the user since the test result is non-quantitative.
6.8 Pull-In Point Testing:
6.8.1 This test is to evaluate the risk of injury to the user or to a third party due to inadvertent contact between either rotating
and fixed components of the sample or between the belts/ropes/chains of the sample and their respective cams, pulleys, or
sprockets. The results of this test determine the adequacy of spacing between components or the adequacy of the guarding of those
components, or both. Methodology entails insertion of a sized probe into the pull in areas discussed in Specification F2216. It has
been assumed that contact in these areas is inadvertent and therefore the test will be perpendicular and through the area in question
and not articulated into all possible areas around the potential hazard.
6.8.2 Apparatus and Set Up—The sample shall be set up as described in 5.1 with the upholstered pads reinstalled. This test
requires a probe as specified in Fig. 3. This test also requires a sized probe of 25 mm (0.98 in.). Verify that all guards are properly
positioned and secured. An apparatus capable of measuring 4.4 N (1 lb) of pulling force shall be provided. Pressure measuring film
2 4
capable of measuring 90 N/cm (131 psi) shall be provided.
6.8.3 Calibration—Calibrate the load measurement apparatus to confirm accuracy to within 60.5 N (0.1 lb). Verify that the
probe conforms to the dimensions shown in Fig. 3. Verify that the 9.5 mm (0.37 in.) sized probe is no less than the stated size and
that the other sized probes are no greater than their stated sizes.
6.8.4 Procedure—The evaluator shall place himself/herself on the sample in the operational position and determine and note
regions of the sample that are to be evaluated. Specification F2216 must be referred to in order to determine which areas shall be
evaluated. Areas of concern that are 1800 mm (71 in.) or more above the floor are exempt from this requirement and do not need
to be examined further. Areas that are blocked by the user of the equipment through out throughout the range of motion are also
The sole source of supply of the film (Fuji Prescale Film—single sheet type for high pressure) known to the committee at this time is Fuji Photo Film Co. Ltd, Tokyo,
Japan or their distributors. If you are aware of alternative suppliers, please provide this information to ASTM International Headquarters. Your comments will receive careful
consideration at a meeting of the responsible technical committee, which you may attend.
F2277 − 17a
exempt from further examination. The evaluator shall pay attention to areas outside their field of view and areas outside their reach
as discussed in Specification F2216. The evaluator shall insert the probe perpendicular to the area in question, parallel to the axis
of rotation or plane of motion and cycle the machine through one stroke with the full amount of resistance for the specimen
selected. If the probe becomes entrapped during either the outward or return stroke, apply a pulling force to remove the probe.
Record the force required to remove the probe. For areas requiring more than 4.4 N (1 lb) of removal force apply the pressure
measuring film per the manufacturer’s instructions and cycle the machine again with the full resistance selected. Record the
pressure reading obtained from the film.
6.8.5 Pass/Fail Criteria—The probe shall not become entrapped in any mechanical hazard. Pull-in is defined to have occurred
if the force to pull out the probe is greater than 4.4 N (1 lb). Pull in areas in rope and belt driven machines where the pressure
recorded on the pressure measuring film is 90 N/cm (131 psi) or less shall be exempt from guarding requirements.
6.8.6 Precision and Bias—No information is presented about either the precision or bias of test in 6.8 for evaluating pull in
points since the test results are non-quantitative.
6.9 Weight Stack Enclosure Design:
6.9.1 This test is a visual and physical test to evaluate the design of the weight stack enclosure provided with the sample.
Methodology entails the visual examination of the weight stack enclosure relative to the user’s placement on the machine and the
insertion of a sized probe into the areas between the weights and the enclosure.
6.9.2 Apparatus and Set Up—The sample shall be set up as described in 5.1 with the upholstered pads reinstalled. The sample
shall have the weight stack enclosure installed per the manufacturer’s instructions. This test requires sized probes of 9.5 mm (0.37
in.), 25 mm (0.98 in.), and 60 mm (2.36 in.).
6.9.3 Calibration—Verify that the 9.5 mm (0.37 in.) sized probe is no less than the stated size and that the other sized probes
are no greater than their stated sizes.
6.9.4 Procedure—The evaluator shall place himself/herself on the sample in the operational position and determine and note
where the weight stack is relative to their field of vision while using the machine. Referring to Specification F2216, the evaluator
shall determine the amount of guarding required around the weight stack. Measure and record the spacing provided between the
enclosure halves for insertion of the weight selection pin. Measure and record the extension of the enclosure beyond the furthest
range of travel of the weight stack for a user of 1.8 m (74 in.) stature. With the weights in the rest position, measure and record
the spacing between the weights and the enclosure.
6.9.5 Pass/Fail Criteria—Spacing for insertion of the weight selection pin that exceeds 75 mm (2.95 in.) shall fail the test.
Enclosures that do not extend 60 mm (2.36 in.) past the furthest range of travel of the weight stack fail the test. Enclosures that
are between 9.5 mm (0.37 in.) and 25 mm (0.98 in.) from the edges of the weights shall fail the test.
6.9.6 Precision and Bias—No information is presented about either the precision or bias of test in 6.9 for evaluating weight
stack enclosure design since the test result is non-quantitative.
6.10 Load Testing:
6.10.1 Endurance Cycle Testing—This test is a visual and physical inspection of the specimen to ensure that it shall withstand
endurance cycles set forth in Specification F2216 without failure.
6.10.1.1 Apparatus and Set Up—The sample shall be set up as described in 5.1 with the maximum resistance available for the
product. It is acceptable, for this test, to anchor the machine to the floor to prevent “walking.” Note and record whether the
specimen is intended for consumer or institutional use. Obtain instruction or a descriptive explanation of the function of the sample
machine from the manufacturer. A nonimpact method of cycling the machine through at least 80 % of its normal range of motion,
as defined by the manufacturer, shall be provided. A method of recording the number of cycles shall be provided. A method of
loading the machine with extrinsic loads experienced during the cycling of the machine shall be provided.
6.10.1.2 Calibration—Verify the accuracy of the cycle counting device to 61 cycle.
6.10.1.3 Procedure—Determine from the manufacturer’s specifications the maximum range of travel for the machine. Construct
and attach to the user means of the machine an apparatus capable of moving the user means through 80 % of this range while
loaded with the maximum resistance of the machine. The testing apparatus shall move the user means in the same manner that the
user does. For example, if the user contacts the user means in two locations then the testing apparatus must do so as well. If during
the course of operation the machine receives loading from the user via the user means then this shall be considered and figured
into the design of the testing apparatus. If the user’s body weight is a factor in the loading of the machine during cyclic operation
then 135 kg (300 lb), simulating a user, shall be attached to the user support surface at the point of user contact.
(1) The design of the testing apparatus will be unique and different for each product tested. Careful consideration shall be given
by the testing facility as to how the test apparatus is constructed and they shall communicate with the manufacturer prior to
commencing the test to verify that the apparatus functions in a manner similar to how a user would actually use and interface with
the machine.
(2) Verify that the counter cycles for each repetition of the machine. Verify that after each repetition the load at the user means
returns to zero prior to the execution of the next repetition. This may be done with a load cell or simple visual examination of the
system. If the test apparatus is to run unattended then it shall be outfitted with a means of stopping if failure occurs on the sample.
Begin the test. Periodically make and record observations during the test.
F2277 − 17a

the test on the remaining stations.
(4) Upon completion of the cycles specified in Specification F2216 reinstall the upholstered pads and use the machine
according to the instructions provided by the manufacturer.
6.10.1.4 Pass/Fail Criteria—Machines or components that fail to attain the minimum number of cycles specified in
Specification F2216 shall fail the test. Mac
