5 Safety requirements 5.1 General Depending on the design of the piece of equipment the following additional requirements to EN 957-1 shall apply as appropriate. 5.2 External construction 5.2.1 Squeeze and shear points within the accessible area Elliptical trainers shall be free of squeeze and shear points. Test in accordance with 6.2. 5.2.2 Temperature rise When tested in accordance with 6.3, accessible parts of the elliptical trainer shall not have a temperature greater than 65 °C. 5.3 Intrinsic loading 5.3.1 Class H Each piece of equipment of class H loaded with the user’s body mass shall withstand 2,5 times the body mass (100 kg) without breakage. Test in accordance with 6.4. 5.3.2 Class S The training equipment shall withstand four times the body mass (100 kg) without breakage. Each piece of equipment of class S loaded with the user’s body mass shall withstand two times the body mass (100 kg). When tested according to 6.4, supports (e.g. load-bearing surfaces) shall not be deformed by more than f = 1/100, cantilever supports (cantilever surfaces) by more than f = 1/150 and other dimensions by more than 1 %. A body mass of 100 kg is taken as the nominal load. After the test supports (e.g. load-bearing surfaces) shall not be deformed by more than f = 1/100; cantilever supports (cantilever surfaces) by more than f = 1/150; other dimensions by more than 1/100. 5.4 Handlebars The handlebars shall show no permanent deformation of more than 3 % when tested in accordance with 6.5. To reduce the danger of penetration the section of the tip of the handlebar shall have a minimum diameter of 50 mm. Test in accordance with 6.1.1. 5.5 Footplatforms The footplatforms shall have a non slip surface of at least 300 mm 100 mm and with a friction factor of more than 0,5, when tested in accordance with ISO 5904. The footplatform shall have a guard with at least 30 mm height along the inside edge and the front edge. 5.6 Stability When tested in accordance with 6.6, the training equipment shall not fall over. 5.7 Endurance When tested in accordance with 6.7, the training equipment shall withstand 12 000 cycles for class H and 100 000 cycles for class S. After the test the training equipment shall be capable of functioning according to the manufacturer’s instructions for the correct use and shall not show any signs of damage. 5.8 Additional requirements for class A The variation of the indicated or determined power P from the power input shall not exceed 5 W up to 50 W and 10 % over 50 W. Test in accordance with the manufacturer’s power measurement description. 6.5 Testing of handlebars For non-movable handlebars, apply a test force of 1 000 N vertically in the most onerous position of the handlebar for a period of 5 min. Then apply a force of 500 N using a belt with a width of (80 5) mm in the same position as in the vertical test but in the most onerous horizontal direction of the handlebar for a period of 5 min. For movable handlebars load the footplatform with a nominal load on the same side as the movable handlebar being tested. Apply a test force of 1 000 N in a dynamic direction in the most onerous position for a period of 5 min. Then test the movable handlebar at 90° to the training direction. Apply a test force of 200 N in the most onerous position for a period of 5 min. 6.6 Testing of stability Carry out the test in the most onerous position. A test person weighing (100 5) kg, height (1 750 50) mm shall train on the training equipment in a normal exer- cise position and operate the equipment at 60 cycles min – 1 for 1 min. Tilt the training equipment 10° in both dynamic directions (forwards and backwards) and 5° in all other directions. NOTE The dynamic direction is that direction in which the body parts of the user are moving.BS-EN-957-9  pdf download.
