12、04, the friction factor of the peWstair surface shall be more than 0,5. The minimum width of the foot pedais and stairs excluding the foot guards shall be 100 nun. 5.6 Endurance test When tested in accordance with 6.6, the trallung equipment shall withstand - 12 000 cycles for class H, and - 100 O00

13、 cycles for class S. After the test the training equipment shall be capable of functioning in accordance with the manufacturers instructions for the correct use and shall not show any signs of damage, e.g. oil leakage. 6.7 Free wheel In the case of air fan or flywheel assisted steppers, the trammisi

16、57-1: 1996 for class S. Approach the test fingers from all sides to all moving Parts. Determine whether the nger is trapped. 6.3 Testing of temperature rise Apparatus: contact thermometer with an accuracy of fl “C. Carry out these tests using (100 5) kg test subjects. Operate the Imhhg equipment at

17、60 stepdmin fl0 % for 20 min. The step height shall be (180 i 5) nun when measured ai the centre of the foot pedal or the maximum possible step height of the equipment if this is not achievable. Page 7 EN 9578:1998 The resistance shall be set at the maximum resistance or reduced until 60 stepdmin ca

18、n be maintained without a pause between steps. Note whether the temperature has exceeded 65 OC. For speeddependent training machines carry out the test using a 100 kg load and a paddling speed producing a mechanical power of 180 W f 10 %. 6.4 Testing of intrinsic loading Set the resistance to a cond

19、ition which subjects the macme to a maximum stress. Apply the required test load F for classes H or S without shock for 5 min in the stop position to one pedal over a surface area of 90 nun X 90 mm. Remove the applied load and measure the deformation. Repeat for the other pedal. When more than one f

20、unction is tested, which involves the use of common components, e.g. ropes, pulleys, these can be replaced before each separate test. In order to test the whole drive system, e.g. linkages and frame, place the foot pedal at the mid-point of its range of movement and lock it at the fixing point of th

21、e resistance mechanism furthest away from the foot pedal (e.g. for a dependent stepper lock the other pedal). Apply the load F without shock in the most onerous position over a surface area of 90 mm X 90 mm of the foot pedal or stair so that the whole system is subjected to stress (see Figure 6). -

Next, apply a force of 500 N horizontally using the belt in the me position as in the vertical test but in the most onerous horizont

24、al direction of the handrails or handlebar for a period of 5 min.

25、the equipment if this is not achievable, using a body mass of 100 kg for each foot pedai or stair. For speed-dependent steppers carry out the test with a step height of (180 5) mm in the centre of the pedal movement or the maximum step height if this is not achievable at a step speed which produces

26、an average of 180 W mechanical power f10 %. Perform the endurance test as follows: a) for class H, 12 O00 cycles working for 15 min and rest time 15 min and continue the same pattern until complete; b) for class S, 100 O00 cycles working for 10 h, cool down to room temperature, then continue for fur

27、ther 10 h and continue this method until the test is complete. Check the training equipment is capable of being used as per the manufacturers instsuctions for use. 6.7 Testing of the additional requirement for class A Compare the mechanical power input to the power display. Determine the mechanical

28、power input by calculating the input force over distance (range of movement) and time. The displayed value shall be within f10 % of this measured value in watts using the test parameters of the manufacturer, see clause 7c). The power input shall be the average of a 10 min test period. The test appar

29、atus for measuring force, distance and time shall be accurate to *I % for each of the three variables. 7 Additional instructions for use In addition to EN 957-1, easy-to-understand htructions for use shall be supplied with each stepper, stairclimber and climber.
