6. Sample Preparation
6.1 Assemble and adjust the fitness equipment according to the manufacturer’s instructions. On machines that are fully assembled, verify according to the manufacturer’s instructions that all components are functioning and that they have been adjusted and aligned properly. Unless otherwise stated, the machine must pass the tests without adjustment from this initial condition. 6.2 The individual test methods will describe any variations or modifications that are allowed or are required to the test sample.
7. Test Methods and Procedures
7.1 Stability: 7.1.1 Fitness equipment that is designed for the user to maintain balance as part of its function is not required to meet the stability test (that is, a balance board is not tested for stability). 7.1.2 Fitness equipment shall be tested with and without the simulated user load in the orientation that is least stable.7.1.3 Apparatus and Set-Up—Refer to Fig. 1. Place sample on a non-skid surface inclined at 10° in the orientation that is least stable. The sample shall rest on the supporting surface without anchoring unless the installation instructions for the machine require that the sample be anchored to the floor. Ifthis is the case, then anchor the specimen per the manufacturer’s recommendations. Determine how the user is placed on the machine to perform the exercise (that is, seated, standing, or prone) and then determine how the user’s body weight is distributed onto the user support surfaces. For the simulated use test, a method of applying a steady state load equal to the maximum specified users weight or 100 kg (220 lb), whichever is greater, simulating the user’s weight and its distribution in the vertical direction at the point(s) of user contact must be provided. As an example, for a seated user, the user support surface shall be adjusted to the uppermost position (if adjust- able) and the center of gravity of the load shall be positioned approximatly 300 mm (12 in.) above the user support surface. Possible methods of providing this load include but are not limited to dead weights. 7.1.4 Calibration—Using 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 confirm accuracy to within 620 N (4.5 lb) at the specified load of the maximum specified user weight or 100 kg (220 lb), whichever is greater.7.1.5 Procedure—Test the sample as follows: 7.1.5.1 If the equipment has a storage position that is different than the use position, place or adjust the machine into that position. With the tilt surface inclined to 10° verify that the sample does not tip over. 7.1.5.2 Reposition the sample into the use position. With the sample machine [no user load applied] positioned on the tilt surface verify that the sample does not tip over with the tilt surface inclined to 10°. 7.1.5.3 Using an appropriate load apparatus such as dead weights, distribute a vertical load equal to the maximum specified user weight or 100 kg (220 lb), whichever is greater (65 %), in a non-impact manner to the specimen where the user contacts the machine during normal operation. [If only a portion of the user’s body is supported by the machine during operation, the simulated user weight shall be decreased by the appropriate amount.] Raise and support any adjustable devices or other user means to simulate the furthest point in the range of travel so that its orientation would cause the least stable condition as encountered during normal operation as shown in Fig. 1. Verify that the sample does not tip over. 7.1.6 Pass/Fail Criteria—In none of the above test condi- tions shall the sample tip over. 7.1.7 Precision and Bias—No information is presented about either the precision or bias of the test for measuring stability since the test result is non-quantitative. 7.2 Edge Sharpness: 7.2.1 The purpose of this test is to verify that there are no edges in the accessible area that would constitute a risk of injury. Where there is uncertainty, a sharp-edge tester as specified by UL 1439 is to be employed.
