Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 normal operation, nthe operation of the selectorized strength equipment as defined by the manufacturer.4. Significance and Use4.1 The purpose of these test methods is to provide valid and repeat
17、able 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 reliability of selectorized strength equipment design and reduce
18、 the risk of seriousinjury resulting from design deficiencies.5. Certification5.1 These test methods permit self-certification. It is recommended that each manufacturer employ an independent laboratoryto evaluate and validate that their designs and test procedures conform and comply to these test me
19、thods and Specification F2216.6. Units of Measure6.1 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.7. Sample Preparation7.1 Assemble and adjust the selectorized strength equipment according to the manufacturers instructions. Remo
20、ve upholsteredpads from the sample. On machines that 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
21、initial condition. Selectorized strength equipment shall be provided with the largest weightstack offered by the manufacturer for the model to be tested.7.2 The individual test methods will describe any variations or modifications that are required to the test sample.8. Test Methods and Procedures8.
22、1 Stability:8.1.1 Selectorized strength equipment shall be tested with and without the simulated user load in the orientation that is mostobviously unstable.8.1.2 Apparatus and Set-UpRefer to Fig. 1. Place sample on a non-skid surface inclined at 10 in the orientation that is leaststable. The sample
23、 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 recommendations.Determine how the user is placed on the machine to perform
24、 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) simulating the users weight and its distribution in the vertica
25、l 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 position2For referenced ASTM standards, visit the ASTM website, www.astm.org, or contact ASTM Customer Service at serviceastm.org.

27、y 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.8.1.3 CalibrationUsing an angle measuring instrument accurate to within 0.1, verify the non-skid surface is 10 6 0.5.Calibrate the load meas
28、urement apparatus to confirm accuracy to within 620 N (4.5 lb) over entire 981 N (220 lb) range.8.1.4 ProcedureTest the sample as follows:8.1.4.1 With the sample machine (no user load applied) positioned on the tilt surface, verify that the sample does not tip overwith the resistance means in the re
29、st position.8.1.4.2 Using the aforementioned load apparatus, distribute a vertical load equal to 100 kg (220 lb) 6 5 % in a non-impactmanner to the specimen where the user contacts the machine during normal operation. (If only a portion of the users body issupported by the machine during operation,
30、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 duringnormal operation of the machine by a user of 1.8 m (74 in.) stature. Verify that the sa
31、mple does not tip over.8.1.4.3 Repeat 8.1.4.1 and 8.1.4.2 with the sample oriented in any other directions of potential instability.8.1.5 Pass/Fail CriteriaIn none of the above test conditions shall the sample tip over.8.1.6 Precision and BiasNo information is presented about either the precision or
32、 bias of test 8.1 for measuring stability sincethe test result is non-quantitative.8.2Edge Sharpness8.2 Weight Stack Travel:8.2.1The purpose of this test is to verify that there are no edges in the accessible area that would constitute a risk of injury. Wherethere is uncertainty, a sharp-edge tester
33、 as specified by UL 1439 is to be employed.8.2.1 This test is a visual inspection of the sample to ensure that the weight stack travels freely along its guide means and returnsto its initial position after the displacing force has been removed.8.2.2 Apparatus and Set UpThe sample shall be set up as
34、described in 7.1.8.2.3 CalibrationCalibrate sharp-edge tester per UL 1439. No calibration required. Visual inspection only.8.2.4 ProcedureExamine the accessible areas by visual and tactile means to ensure all parts are burr-free, rounded, orotherwise insufficiently sharp to constitute a risk of inju
35、ry. Wherever there may be uncertainty as to the sharpness of an edge, usethe edge tester and conduct the test per UL 1439. Move the lifting arm through its range of travel and verify that the weight stackFIG. 1 Tilt TestF2277 123moves along a guide means in a controlled manner and returns to its ini

The weight stackmust begin and end the test in the same rest position and must not move unless it is displaced intention
