Like other physical activities, exercise involving fitness equipmentinvolves the risk of injury, particularly if the equipment is used improperly or not properly maintained.In addition, use

4、rs with physical limitations should seek medical advice or instruction from the fitnessfacility, or both, prior to using this equipment. Certain physical conditions or limitations may precludesome persons from using this equipment properly and without increasing the risk of serious injury.1. Scope1.

5、1 These test methods specify procedures and equipmentused for testing and evaluating elliptical trainers for compli-ance to Specification F2810. Both design and operationalparameters will be evaluated. Where possible and applicable,accepted test methods from other recognized bodies will beused and r

The evaluator shall also usethe elliptical trainer per the manufacturers instructions andobserve the orientation of the end portion of the movablehandlebars with respect to the head of the evaluator throughoutthe range of travel

24、 of the movable handlebars.6.2.3.4 Pass/Fail CriteriaThe dimension of the end por-tion of the movable handlebar shall be at least 50 mm (1.97 in.)in diameter. Alternately, if the end portion of the movablehandlebars is always angled away from the user duringoperation of the elliptical trainer then i

27、nput to the elliptical trainer can be accomplished bysecuring weight to the foot pedals and lifting the weight usingpneumatic cylinders, or by pushing down with pneumaticcylinders (with or without weight). Regardless of how the loadis input to the elliptical trainer under test, careful consideration

28、shall be given by the testing facility as to how the test apparatusis constructed. The testing facility shall communicate with themanufacturer prior to commencing the test and verify that theapparatus functions and loads the elliptical trainer in a mannersimilar to how a user would actually use and

29、interface with theelliptical trainer. Figs. 1 and 2 illustrate pneumatic apparatusesthat have been used successfully to conduct endurance testing.The elliptical trainer shown in Fig. 2 is driven by the twopneumatic cylinders which are attached to the footplates of thedevice under test. The cylinders

30、 can be pivoted or mounted tolinear bearings on the test apparatus frame so that the cylindersare able to follow the horizontal motions of the ellipticalpedals. The timing of the cylinder actuations can be such thatthe pistons are pushing downward generally synchronous to theFIG. 1 Isometric View of

By timing the firing of the cylinders correctly, along withvarying the braking resistance, this setup will drive theelliptical trainer. Horizontal loading of the moveable handle-bars (if equipped) c

The testing appa-ratus shall move the foot supports through t

36、heir complete cyclein the same manner that the user does.Apply the test load to thepedals. Set the braking resistance to 80 % of the possibleresistance capable by the brake or 300 watts, whichever is less.The speed of the test is dependant on the pedal loading and thebrake resistance setting. Theref

37、ore, there will not be a stringentrequirement for the speed of this test. It is recommended thatspeed end up between 30 and 60 cycles per minute, (one cycle= one full revolution of the pedal) once the pedal loading andthe brake resistance have been set. The duty cycle of the testshall be a minimum o
