This part of EN 957 is applicable to stationary training
27、equipment type stationary exercise bicycles and upper body crank training equipment (type 5) as defined in Clause 3 within the classes S, H, I and A, B, C according to EN 957-1. Any attachment provided with the stationary exercise bicycles and upper body crank training equipment for the performance
28、of additional exercises are subject to the requirements of EN 957-1. This part of EN 957 is not applicable to roller stands as they cannot be made safe in a reasonable way. 2 Normative references The following referenced documents are indispensable for the application of this document.

45、the piece of training equipment the following requirements shall apply as appropriate. Unless stated otherwise a tolerance of 5 % applies. 5.2 External construction 5.2.1 Transmission elements and rotating parts When tested in accordance with 6.3.1, the finger probe shall not become entrapped. In ad
46、dition, if the crank extends beyond the protective cover at any point during rotation, then the distance between the crank and the protective cover shall not be less than 10 mm. Test in accordance with 6.1.1. Transmission elements, fans and flywheels shall be protected, so that, when tested accordin
47、g to 6.3.2, the test finger cannot be trapped or touch moving parts which have no smooth surface. 5.2.2 Temperature rise When tested in accordance with 6.2, accessible parts of the equipment shall not have a temperature greater than 65 C. 5.3 Intrinsic loading For classes S, H and I the training equ
48、ipment shall be tested against permanent deformation with 2 times the maximum body mass 5 % specified by the manufacturer or at least 2 000 N whichever is greater. After the test in accordance with 6.4, the permanent deformation shall be not more than 3 %. For class H the training equipment shall not break when tested with a load of 2,5 times the maximum body mass 5 % specified by the manufacturer or at least 2 500 N whichever is greater. For classes S and I the trai
