For Annual Book of ASTM Standardsvolume information, refer to the standards Document Summary page on the ASTM website.F2277 1726.1.2 Apparatus and Set-UpRefer to Fig. 1. Place sample on a non-skid surface inclined at 10 in the orientation that is leaststable
26、.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 recommendations.Determine how the user is placed on the machine
27、 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) simulating the users weight and its distribution in
28、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 be positioned approximately 300 mm (12 in.) above
29、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 0.5.Calibrate the load measurement apparatus to con
30、firm accuracy to within 620 N (4.5 lb) over entire 981 N (220 lb) range.6.1.4 ProcedureTest 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 overwith the resistance means in the rest position.6.1.4.2 Usin
31、g 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, the 100 kg (220 lb) simu
32、lated 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 sample does not tip over.6
33、.1.4.3 Repeat 8.1.4.16.1.4.1 and 8.1.4.26.1.4.2 with the sample oriented in any other directions of potential instability.6.1.5 Pass/Fail CriteriaIn none of the above test conditions shall the sample tip over.6.1.6 Precision and BiasNo information is presented about either the precision or bias of t
34、est 8.16.1 for measuring stabilitysince 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 returnsto its initial position after the displacing force has been removed
35、.6.2.2 Apparatus and Set UpThe sample shall be set up as described in 7.15.1.FIG. 1 Tilt TestF2277 1736.2.3 CalibrationNo calibration required. Visual inspection only.6.2.4 ProcedureMove the lifting arm through its range of travel and verify that the weight stack moves along a guide meansin a contro
36、lled manner and returns to its initial position as the lifting arm is returned to its initial rest position.6.2.5 Pass/Fail CriteriaThe weight stack must begin and end the test in the same rest position and must not move unless itis displaced intentionally by a lifting force applied to the lifting a
37、rm.6.2.6 Precision and BiasNo information is presented about either the precision or bias of test in 8.26.2 for evaluating weightstack 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 sele
38、ctor pin to ensure that the design features a retentiondevice and that it functions properly.6.3.2 Apparatus and Set UpThe sample shall be set up as described in 7.15.1. Obtain instructions or a descriptive explanationof the function of the weight stack selector pin from the manufacturer.6.3.3 Calib
39、rationNo calibration required. Visual and function inspection only.6.3.4 ProcedureInspect the weight stack selector pin and ensure that it features a retention device that will not allow the pinto be removed from the weight stack unless it is intentionally removed. Examples of retention devices incl
40、ude, but are not limitedto, spring activated detent balls or a physical deformation of the pin and comparable retention zone on the weight plate. Theoperation of the retention system shall be self-evident. Insert the weight stack selector pin into a weight on the weight stack andverify that the rete
41、ntion mechanism functions properly.6.3.5 Pass/Fail CriteriaWeight stack selector pins that do not have a retention means shall fail this test. Retention mechanismsthat do not function according to the instructions provided by the manufacturer shall fail this test.6.3.6 Precision and BiasNo informati
42、on is presented about either the precision or bias of test in 8.36.3 for evaluating weightstack 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
43、assist means is required andthen ensure that the design functions properly.6.4.2 Apparatus and Set UpThe sample shall be set up as described in 7.15.1. Reinstall the upholstered pads for this test.Obtain instructions or a descriptive explanation of the function of the assist mechanism(s) used on the
44、 sample from themanufacturer.6.4.3 CalibrationNo calibration required. Visual and function inspection only.6.4.4 ProcedureAdjust the machine for the evaluators size according to the manufacturers instructions. The evaluator shallenter the machine and attempt to get into the exercise start position a
45、s described in the operation instructions provided by themanufacturer. The evaluator shall be able to get into and back out of the starting position with relative ease. If the lifting or usermeans cannot be reached by the evaluator or if the evaluator cannot get into the starting position easily, th
46、en further adjustmentof the machine may be required. If this is not the case (the machine is properly adjusted per the operation instructions for the givenbody size of the evaluator), then an assist means that moves the lifting or user means into the direction of lifting stroke must beprovided.6.4.4
47、.1 If an assist means is provided, then operate the mechanism and ensure that it performs as described in the operationinstructions. Upon actuation of the assist means, the lifting or user means shall move into the direction of machine motion allowingthe user to get into the loaded exercise start po
48、sition. Upon completion of the exercise and return of the lifting or user means tothe 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
49、Machines that do not allow the user to enter or exit the machine easily shall fail the test. Assistmechanisms that do not function according to the instructions provided by the manufacturer shall fail test.Assist mechanisms thatdo 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 travelof the lifting or user means shall fail the test.6.4.6 Precision and BiasNo information is presented about either the precision or bias of test in 8.46.4 for evaluating assistmechanis
