29、heelliptical trainer per the manufacturers instructions and observe the orientation of the end portion of the movable handlebars withrespect to the head of the evaluator throughout the range of travel of the movable handlebars.F2811 1526.2.3.4 Pass/Fail CriteriaThe dimension of the end portion of th
30、e movable handlebar shall be at least 50 mm (1.97 in.) indiameter.conform to dimensional requirements of subsection 5.2 of Specification F2810. Alternately, if the end portion of themovable handlebars is always angled away from the user during operation of the elliptical trainer then it shall be con
31、cluded thatthe movable handlebars meet the requirements of the specifications.6.2.3.5 Precision and Bias:(1) PrecisionThe precision of this test method has not been determined.(2) BiasThe bias of this test method includes quantitative estimates of the uncertainties of the measuring devices, thecalib
32、rations of testing equipment and the skill of the operators.At this time, the statements on bias should be limited to documentedperformance of particular laboratories.6.3 EnduranceThe purpose of this test is to confirm the endurance of the main components of the elliptical trainer. Load inputto the
33、elliptical trainer can be accomplished by securing weight to the foot pedals and lifting the weight using pneumatic cylinders,or by pushing down with pneumatic cylinders (with or without weight). Regardless of how the load is input to the elliptical trainerunder test, careful consideration shall be
34、given by the testing facility as to how the test apparatus is constructed. The testing facilityshall communicate with the manufacturer prior to commencing the test and verify that the apparatus functions and loads theelliptical trainer in a manner similar to how a user would actually use and interfa
35、ce with the elliptical trainer. Figs. 1 and 2 illustratepneumatic apparatuses that have been used successfully to conduct endurance testing. The elliptical trainer shown in Fig. 2 isdriven by the two pneumatic cylinders which are attached to the footplates of the device under test. The cylinders can
36、 be pivotedor mounted to linear bearings on the test apparatus frame so that the cylinders are able to follow the horizontal motions of theelliptical pedals. The timing of the cylinder actuations can be such that the pistons are pushing downward generally synchronousto the downward motion of the foo
37、tplate as it follows the elliptical path. By timing the firing of the cylinders correctly, along withvarying the braking resistance, this setup will drive the elliptical trainer. Horizontal loading of the moveable handlebars (ifequipped) can be accomplished by connecting the handlebars to hanging we
38、ights using a cable over a pulley. Other methodsinclude but are not limited to un-powered air cylinders with controlled venting, connection to elastic materials, a clamped weightpositioned so that the peak load in the dynamic direction is 5 % of the maximum specified user weight or a pneumatic cylin
39、derapplying a reversed cyclic load of 5 % of the maximum specified user weight to handlebars that are held static in a test fixture.6.3.1 Apparatus and Set UpThe sample shall be set up as described in 5.1. Obtain instruction or a descriptive explanation ofthe function of the sample equipment from th
40、e manufacturer. A method of recording the number of cycles shall be provided.6.3.2 CalibrationVerify that the load application system is calibrated and is accurate to within 5 % of the applied load. Verifythat the counting device changes the displayed counts by 1 for each full revolution of one foot
41、 pedal for at least 100 cycles.6.3.3 ProcedureConstruct and attach the resistance and cycling means to the elliptical trainer and verify that it functions asintended by the manufacturer. The testing apparatus shall move the foot supports through their complete cycle in the same mannerthat the user d
42、oes. Apply the test load to the pedals. Set the braking resistance to 80 % of the possible resistance capable by thebrake or 300 watts, whichever is less. The speed of the test is dependant on the pedal loading and the brake resistance setting.Therefore, there will not be a stringent requirement for
43、 the speed of this test. It is recommended that speed end up between 30 and60 cycles per minute, (one cycle = one full revolution of the pedal) once the pedal loading and the brake resistance have been set.The duty cycle of the test shall be a minimum of 50 % on and 50 % off, with a minimum on time
44、of 30 min.FIG. 1 Isometric View of a Pivoting Test ApparatusF2811 1536.3.3.1 Verify that the counter cycles for each repetition of the elliptical trainer and then periodically throughout the durationof the test. If the test apparatus is to run unattended, then it shall be outfitted with a means of s
45、topping if failure occurs on thesample. Begin the test. Periodically make and record observations during the test.6.3.4 Pass/Fail CriteriaUpon completion of the cycles specified in Specification F2810, the trainer shall function as per theoperation instructions provided by the manufacturer.manufactu

47、alibrations of testing equipment and the skill of the operators.At this time, the statements on bias should be limited to documentedperformance of particular laboratories.6.4 Static Loading of StructuresThe purpose of this test is to evaluate the static structural integrity of the foot supports, any
48、frame structure and user supports (moveable and static handlebars), as applicable to user safety.6.4.1 HandlebarsThe purpose of this test is to confirm structural integrity of handlebars in the vertical and horizontally loadedconditions.6.4.1.1 Apparatus and Set UpThe sample shall be set up as descr
49、ibed in 5.1. Supply a means of applying a steady state loadin both the vertical and horizontal directions. Possible methods of providing that force include, but are not limited to, pneumaticcylinder(s), or dead weights. If necessary, the elliptical trainer may be restrained from movement as long as that restraint does notaid the structure of the user support means. Determine which direction in the horizontal direction would be structurally the weakest.6.4.1.2 CalibrationVerify the load application system is calibrated and is accurate to withi
