1、Designation: F2216 17 An American National StandardStandard Specification forSelectorized Strength Equipment1This standard is issued under the fixed designation F2216; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of las
2、t revision. A number in parentheses indicates the year of last reapproval. 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 training
3、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 necessaril
4、y 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 instructi
5、on 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 parameters for
6、the designand manufacture of selectorized strength training equipment asdefined in 3.1.1.2 It is intended that these fitness products be used in anindoor setting or environment.1.3 It is the intent of this standard to specify fitness productsfor use only by individuals age 13 and older.1.4 This stan
7、dard is to be used in conjunction with Speci-fication F2276, Test Methods F2571, and Test Method F2277.1.5 This standard takes precedence over SpecificationF2276 and Test Methods F2571 in areas that are specific orunique to selectorized strength training equipment.1.6 This specification2establishes
8、additional requirementsfor the design of commercial fitness equipment for use bypeople with functional limitations or impairments.1.7 The values stated in SI units are to be regarded as thestandard. The values in parentheses are for information only.1.8 This standard does not purport to address all
9、of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.1.9 This international standard was developed in accor-dance with
10、 internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade (TBT) Committee.2.

Design and Construction Requirements4.1 Construction:4.1.1 WeightsWeights shall move only when displace
24、dintentionally. Weights shall move freely along their guidemeans and return to the resting point. The travel of the weightsshall be controlled by the user such that no uncontrolledpendulum swing shall occur.4.1.2 Weight Selector PinWeight selector pins shall befitted with a positive retention means.
25、4.1.3 Starting Position AssistIf the user cannot (afteradjusting the machine according to the manufacturers instruc-tions) attain the loaded starting position for the machine, thenthe machine shall be provided with an assist means.4.1.4 Ropes, Belts, Chains, or Other Load TransmissionComponentsRopes
26、, belts, chains, and other means, includingall attachment devices (links, shackles, end fittings, and termi-nation means) shall not fail with a load equal to six times themaximum static tension developed by the machine duringoperation and shall pass the endurance guidelines set forth in4.4.1. All en
27、d terminations shall not be subjected to cyclicbending under normal machine operation as defined by themanufacturer.4.1.5 PulleysPulleys for rope/belt drive machines shallrotate freely under all extrinsic loads.4.1.5.1 Wire Rope PulleysThe groove radius, r,ofthepulley for wire rope driven machines s
28、hall meet the wire ropemanufacturers guidelines and allow for passing of the endur-ance guidelines set forth in 4.4.1. The dimensions shall liewithin the range given:Cd215%toCd2115% (1)with Cd/2 + 10 % being the optimum. Cdis defined as thenominal wire rope diameter including coating. The treaddiame
29、ter, d, of the pulley shall be a minimum of 18 timesgreater than the bare wire rope diameter (without coating). SeeFig. 1.4.1.5.2 Belt PulleysThe diameter of the pulley shall be ofsufficient size to yield a belt life meeting the parametersspecified in 4.4.1. Belt pulleys shall be designed to prevent
30、disengagement through the use of groove, flanges, or othermeans.4.1.6 Rope/Belt GuardsDisengagement of ropes/beltsshall be prevented by the provision of adequate retentionguards or enclosures.4.2 Entrapment Points:4.2.1 General CommentsUnlike other machinery, selec-torized strength equipment is full
31、y controlled by the user of theequipment. It is therefore assumed that the user shall takeresponsibility for his/her actions while using the machine andcan prevent the inadvertent contact with machine componentswithin the users field of view by the user or a third party bystopping the exercise or mo
32、vement of the machine. For thisreason, the discussion of entrapment points is broken downinto “within” and “outside” the field of view of the user.Wherever possible, the design of movable components shallavoid catch, shear, or pull-in points.4.2.1.1 In general, the fingers are the body components mo
33、stlikely to be injured. The primary exception to this is weightstacks, or other frame components, where feet or hands, orboth, could also be injured. Weight stacks shall be spaced lessthan 9.5 mm (0.375 in.) or greater than 25 mm (0.98 in.) fromany fixed frame member. This spacing shall remain const
34、antthrough the travel range of the weight stack. Weight stack toframe spacing greater than 60 mm (2.36 in.) is exempt fromthis requirement. Weight stacks shall be spaced at least 60 mm(2.36 in.) from the base frame of the machine. StrengthF2216 172equipment that includes weight stack enclosures desi
35、gned inaccordance with 4.3 as a permanent feature of the machine areexempt from this requirement, provided that the enclosureextends past the rest position of the bottom weight plate.4.2.1.2 The user means or other moving components, orboth, shall not pass within 60 mm (2.36 in.) of the movingweight
36、 stack, or other frame components, during the normaloperation of the machine, as defined in the instructionsprovided by the manufacturer. Mechanical stops are generallyprovided at one or both extremes of the user means range oftravel. Since the user means will contact the stops at theselocations, th
37、ey are excluded from the clearance requirements.However, if the stop is physically part of the moving usermeans, then it shall pass no closer than 25 mm (0.98 in.) to anyfixed frame members throughout its range of travel.4.2.1.3 If the machine framework or the users bodyplacement, while using the ma
38、chine in accordance with themanufacturers instructions, prevents the uncontrolled accessof a third party into the area of concern, then guarding is notrequired. For this exemption, the users body must preventaccess throughout the entire exercise range of motion.4.2.2 Outside the Field of ViewTo a he
39、ight of 1800 mm(70.8 in.), the distance between movable components orbetween a movable and fixed component shall be at least 60mm (2.36 in.) when body parts other than the fingers are at risk.This dimension may be reduced to no less than 25 mm (0.98in.) when only the fingers are at risk. If the spac
40、ing betweenmoving components or between fixed and moving componentsremains constant throughout the range of motion of themachine, then the spacing shall be greater than 25 mm (0.98in.) or less than 9.5 mm (0.375 in.). Guarding shall be providedif the design does not allow the above dimensions to be
41、met.4.2.3 Within the Field of View and Within Reach of theUserIf distances do not conform to those specified in 4.2.2,the components shall be guarded or enclosed.4.2.4 Within the Field of View and Outside the Reach of theUserMoving components within the users field of view butaccessible only to a th
42、ird party shall not be located within 25mm (0.98 in.) of a stationary component. Alternatively, suchpoints can be less than 9.5 mm (0.375 in.) from a stationarycomponent if the spacing between the components remainsconstant throughout the range of movement of the machine.4.2.5 Pull-In PointsFinger p
43、ull-in occurs when the spac-ing between the fixed and rotating component is less than 25mm (0.98 in.) or when the angle between the fixed guard andthe belt or rope is less than 50, or both (see Fig. 2). For ropesand pulleys or ropes and cams, pull-in will occur during theportion of the exercise stro
44、ke that the rope wraps onto therotating element or passes into the guard. This can occur onboth sides of a pulley or guard as shown in Fig. 2 and Fig. 3.Fig. 4 illustrates a circular pulley or cam guard. To achieve apull-in angle greater than 50, the guard radius Grshall becalculated using the equat
45、ion shown in Fig. 4.4.2.5.1 Outside the Field of ViewPull-in points up to aheight of 1800 mm (70.8 in.) shall be guarded or spaced greaterthan 25 mm (0.98 in.) apart so that the users or third partysFIG. 1 Wire Rope Pulley ProfileF2216 173fingers, when extended, cannot be caught between the compo-ne
46、nts (see Fig. 2). Rope, belt, or rope driven machines wherethe pressure between the rope/belt and the cam or pulley is lessthan 90 N/cm2(131 psi) are excluded from this requirement.4.2.5.2 Within the Field of ViewPull-in points within reachof the user when in the exercise position shall be guarded s
47、othat the users fingers cannot be caught between the compo-nents. Pull-in points within the field of view of the user, duringthe entire range of motion of the exercise being performed, butaccessible only to a third party, need not be guarded becausethe user can control the motion of the machine and
48、thus preventany inadvertent contact with a third party. A site specific labelshall be present in the immediate location of the pull-in point,alerting the user or a third party to the potential for injury andto stay clear of the area. Rope or belt driven machines wherethe pressure between the rope/be
49、lt and the cam or pulley is lessthan 90 N/cm2(131 psi) are excluded from the requirements of4.2.5.1 and 4.2.5.2.4.3 Weight Stack Enclosures:FIG. 2 Guarding of Pull-In PointsUnguardedF2216 1744.3.1 GeneralUnlike other fitness equipment, selectorizedstrength equipment is fully controlled by the user. Stopping theexercise or the machines movement permits the user toprevent inadvertent contact with weight stacks within the fieldof view of the user. Weight stack enclosures may assist inpreventing uncontrolled access by third parties outs
