Significance and Use4.1 The purp

17、ose of these test methods is to provide valid and repeatable test methods for the evaluation of selectorized strengthequipment assembled and maintained according to the manufacturers specifications. Use of these test methods in conjunction withSpecification F2216 is intended to maximize the reliabil

18、ity of selectorized strength equipment design and reduce the risk of seriousinjury resulting from design deficiencies.5. Sample Preparation5.1 Assemble and adjust the selectorized strength equipment according to the manufacturers instructions. Remove upholsteredpads from the sample. On machines that

19、 are fully assembled, verify according to the manufacturers instructions that allcomponents are functioning and that they have been adjusted and aligned properly. Unless otherwise stated, the machine must passthe tests without adjustment from this initial condition. Selectorized strength equipment s

20、hall be provided with the largest weightstack 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 Procedures6.1 Stability:6.1.1 Selectorized strength equipment sh

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-UpRefer to Fig. 1. Place sample on a non-skid surface in

22、clined at 10 in the orientation that is leaststable.The sample shall rest on the supporting surface without anchoring unless the installation instructions for the machine requirethat the sample be anchored to the floor. If this is the case, then anchor the specimen per the manufacturers recommendati

23、ons.Determine how the user is placed on the machine to perform the exercise (that is, seating, standing, or prone) and then determinehow the users body weight is distributed onto the user support surfaces. For the simulated use test, a method of applying a steadystate load equal to 100 kg (220 lb) s

24、imulating the users weight and its distribution in the vertical direction at the point(s) of usercontact 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

25、 be positioned approximately 300 mm (12 in.) above theuser support surface. Possible methods of providing this load include, but are not limited to, pneumatic cylinder(s) or dead weights.6.1.3 CalibrationUsing an angle measuring instrument accurate to within 0.1, verify the non-skid surface is 10 6
