Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThe goal of this specification is to promote proper design and manufacturing practices forselectorized strength
3、training equipment. Through these specifications, this specification aims to assistdesigners and manufactures in reducing the possibility of injury when these products are used inaccordance with the operational instructions.The equipment user must recognize, however, that a standard alone will not n
4、ecessarily preventinjuries. Like other physical activities, exercise involving selectorized strength training equipmentinvolves 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 and
5、instruction from the fitnessfacility prior to using this equipment. Certain physical conditions or limitations may preclude somepersons from using this equipment as intended by the manufacturer, and using this equipment mayincrease the risk of injury.1. Scope1.1 This specification establishes parame
6、ters for the design and manufacture of selectorized strength training equipment asdefined in 3.1.1.2 It is intended that these fitness products be used in an indoor setting or environment.1.3 It is the intent of this standard to specify fitness products for use only by individuals age 13 and older.1
7、.4 This standard is to be used in conjunction with Specification F2276, Test Methods F2571, and Test Method F2277.1.5 This standard takes precedence over Specification F2276 and Test Methods F2571 in areas that are specific or unique toselectorized strength training equipment.1.6 This specification2
8、 establishes additional requirements for the design of commercial fitness equipment for use by peoplewith functional limitations or impairments.1.7 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.1.8 This standard does not purport
9、to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety safety, health, and healthenvironmental practices and determine theapplicability of regulatory limitations prior to use.1.9 This international
10、standard was developed in accordance with internationally recognized principles on standardizationestablished in the Decision on Principles for the Development of International Standards, Guides and Recommendations issuedby the World Trade Organization Technical Barriers to Trade (TBT) Committee.2.

Design and Construction Requirements4.1 Construction:4.1.1 WeightsWeights shall move only when displaced intentionally. Weights shall
25、move freely along their guide means andreturn to the resting point. The travel of the weights shall be controlled by the user such that no uncontrolled pendulum swing shalloccur.4.1.2 Weight Selector PinWeight selector pins shall be fitted with a positive retention means.4.1.3 Starting Position Assi
26、stIf the user cannot (after adjusting the machine according to the manufacturers instructions)attain the loaded starting position for the machine, then the machine shall be provided with an assist means.4.1.4 Ropes, Belts, Chains, or Other Load Transmission ComponentsRopes, belts, chains, and other
27、means, including allattachment devices (links, shackles, end fittings, and termination means) shall not fail with a load equal to six times the maximumstatic tension developed by the machine during operation and shall pass the endurance guidelines set forth in 4.4.1. All endterminations shall not be
28、 subjected to cyclic bending under normal machine operation as defined by the manufacturer.4.1.5 PulleysPulleys for rope/belt drive machines shall rotate freely under all extrinsic loads.4.1.5.1 Wire Rope PulleysThe groove radius, r, of the pulley for wire rope driven machines shall meet the wire ro
29、pemanufacturers guidelines and allow for passing of the endurance guidelines set forth in 4.4.1. The dimensions shall lie within therange given:Cd2 15%toCd2 115% (1)F2216 17a2with Cd /2 + 10 % being the optimum. Cd is defined as the nominal wire rope diameter including coating. The tread diameter,d,
30、 of the pulley shall be a minimum of 18 times greater than the bare wire rope diameter (without coating). See Fig. 1.4.1.5.2 Belt PulleysThe diameter of the pulley shall be of sufficient size to yield a belt life meeting the parameters specifiedin 4.4.1. Belt pulleys shall be designed to prevent dis
31、engagement through the use of groove, flanges, or other means.4.1.6 Rope/Belt GuardsDisengagement of ropes/belts shall be prevented by the provision of adequate retention guards orenclosures.4.2 Entrapment Points:4.2.1 General CommentsUnlike other machinery, selectorized strength equipment is fully
32、controlled by the user of theequipment. It is therefore assumed that the user shall take responsibility for his/her actions while using the machine and can preventthe inadvertent contact with machine components within the users field of view by the user or a third party by stopping the exerciseor mo
33、vement of the machine. For this reason, the discussion of entrapment points is broken down into “within” and “outside” thefield of view of the user. Wherever possible, the design of movable components shall avoid catch, shear, or pull-in points.4.2.1.1 In general, the fingers are the body components
34、 most likely to be injured. The primary exception to this is weight stacks,or other frame components, where feet or hands, or both, could also be injured. Weight stacks shall be spaced less than 9.5 mm(0.375 in.) or greater than 25 mm (0.98 in.) from any fixed frame member. This spacing shall remain
35、 constant through the travelrange of the weight stack. Weight stack to frame spacing greater than 60 mm (2.36 in.) is exempt from this requirement. Weightstacks shall be spaced at least 60 mm (2.36 in.) from the base frame of the machine. Strength equipment that includes weight stackenclosures desig
36、ned in accordance with 4.3 as a permanent feature of the machine are exempt from this requirement, provided thatthe enclosure extends past the rest position of the bottom weight plate.4.2.1.2 The user means or other moving components, or both, shall not pass within 60 mm (2.36 in.) of any other fixe
37、d ormoving component, including the moving weight stack, or other frame components, during the stack and frame, during normaloperation of the machine, as defined in the instructions provided by the manufacturer. Mechanical stops are generally provided atone or both extremes of the user means range o
38、f travel. Since the user means will contact the stops at these locations, they areexcluded from the clearance requirements. However, if the stop is physically part of the moving user means, then it shall pass nocloser than 2560 mm (0.98(2.36 in.) to any fixed frame members throughout its range of tr
39、avel.4.2.1.3 If the machine framework or the users body placement, while using the machine in accordance with the manufacturersinstructions, prevents the uncontrolled access of a third party into the area of concern, then guarding is not required. For thisexemption, the users body must prevent acces
40、s throughout the entire exercise range of motion.FIG. 1 Wire Rope Pulley ProfileF2216 17a34.2.2 Outside the Field of ViewTo a height of 1800 mm (70.8 in.), the distance between movable components or between amovable and fixed component shall be at least 60 mm (2.36 in.) when body parts other than th
41、e fingers are at risk. This dimensionmay be reduced to no less than 25 mm (0.98 in.) when only the fingers are at risk. If the spacing between moving componentsor between fixed and moving components remains constant throughout the range of motion of the machine, then the spacing shallbe greater than
42、 25 mm (0.98 in.) or less than 9.5 mm (0.375 in.). Guarding shall be provided if the design does not allow the abovedimensions to be met.4.2.3 Within the Field of View and Within Reach of the UserIf distances do not conform to those specified in 4.2.2, thecomponents shall be guarded or enclosed.4.2.
43、4 Within the Field of View and Outside the Reach of the UserMoving components within the users field of view butaccessible only to a third party shall not be located within 25 mm (0.98 in.) of a stationary any other moving or fixed component.Alternatively, such points can be less than 9.5 mm (0.375
44、in.) from a stationary any other moving or fixed component if the spacingbetween the components remains constant throughout the range of movement of the machine.4.2.5 Pull-In PointsFinger pull-in occurs when the spacing between the fixed and rotating component is less than 25 mm (0.98in.) or when th
45、e angle between the fixed guard and the belt or rope is less than 50, or both (see Fig. 2). For ropes and pulleysor ropes and cams, pull-in will occur during the portion of the exercise stroke that the rope wraps onto the rotating element orpasses into the guard. This can occur on both sides of a pu
46、lley or guard as shown in Fig. 2 and Fig. 3. Fig. 4 illustrates a circularpulley or cam guard. To achieve a pull-in angle greater than 50, the guard radius Gr shall be calculated using the equation shownin Fig. 4.4.2.5.1 Outside the Field of ViewPull-in points up to a height of 1800 mm (70.8 in.) sh
47、all be guarded or spaced greater than25 mm (0.98 in.) apart so that the users or third partys fingers, when extended, cannot be caught between the components (seeFig. 2). Rope, belt, or rope driven machines where the pressure between the rope/belt and the cam or pulley is less than 90 N/cm2(131 psi)
48、 are excluded from this requirement.4.2.5.2 Within the Field of ViewPull-in points within reach of the user when in the exercise position shall be guarded so thatthe users fingers cannot be caught between the components. Pull-in points within the field of view of the user, during the entirerange of
49、motion of the exercise being performed, but accessible only to a third party, need not be guarded because the user cancontrol the motion of the machine and thus prevent any inadvertent contact with a third party. A site specific label shall be presentin the immediate location of the pull-in point, alerting the user or a third party to the potential for injury and to stay clear of thearea. Rope or belt driven machines where the pressure between the rope/belt and the cam or pulley is less than 90 N/cm2 (131 psi)are excluded from the
