This Part of EN 9
27、57 is applicable to stationary training equipment, type strength training equipment (type 2) (hereinafter referred to as training equipment) with the classes S and H. Any attachment provided with the training equipment for the performance of additional exercises is subject to the requirements of EN

31、sign of the piece of training equipment, the following requirements shall apply as appropriate. 5.2 Loading 5.2.1 Intrinsic loading Each piece of equipment loaded with the users body mass shall withstand a force F: for class H: 2,5 times the body mass (100 kg) without breakage; for class S:2 times t
32、he body mass (100 kg). When tested according to 6.2, 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 %. The training equipment shall not break when a static load
33、 of 4 times the body mass is applied. 5.2.2 Extrinsic loading 5.2.2.1 Class H When tested according to 6.3 and loaded with the users body mass and/or reaction forces or moments of the user, each piece of equipment shall withstand without breakage a load F according to the following equation: F(N) =
34、Gk+ 1,5G 3 2,5 3 9,81 where Gis the maximum load in kilograms indicated by the manufacturer (see clause 10 of EN 957-1 : 1996); Gkis the force in kilograms determined by the proportional body mass (100 kg); 1,5 is the dynamic coefficient; 2,5 is the safety coefficient. 5.2.2.2 Class S When tested ac
35、cording to 6.3 and loaded with the users body mass and/or reaction forces or moments of the user, each piece of equipment shall withstand a load F according to the following equation: F(N) = Gk+ 1,5G 3 2 3 9,81(1) where Gis the maximum load in kilograms indicated by the manufacturer (see clause 10 o
36、f EN 957-1 : 1996). The torques as specified in table 1 are to be taken as the basis for the calculation of G if they are greater than the manufacturers stated maximum load; Gkis the force in kilograms determined by the proportional body mass (100 kg); 1,5 is the dynamic coefficient; 2is the safety
37、coefficient.

38、e deformed by more than f = 1/150; and other dimensions shall not be deformed by more than 1 %. If greater than manufacturers maximum stated load, the equipment shall be capable of accepting a minimum torque load as specified in table 1, throughout the range of movement of each exercise for which th
39、e equipment is designed. The training equipment shall not break when a static load according to equation (1) with a safety coefficient of 4 is applied. 5.3 Endurance load When tested according to 6.4, the training equipment shall be capable of normal function. When the training equipment consists of
40、 two or more separate functional units, each shall withstand the endurance load test. When more than one function is tested, which involve use of common components, e.g. ropes, pulleys and bearings, these can be replaced before each separate test. 5.4 Stacked weights 5.4.1 Access to squeeze and/or s
41、hear points 5.4.1.1 General The uncontrolled access by third parties to squeeze and/or shear points of stacked weights shall be prevented. Weights that can only be lifted as a whole block shall not come closer than 60 mm, during movement, to any part of the equipment or the ground. 5.4.1.2 Class H T
42、his can be achieved by either: a) surrounding by a casing in conformance with EN 294, with the exception of a maximum 75 mm wide gap for setting of the weights; or b) by locking the machine to prevent moving of the stacked weights when the equipment is not in use. 5.4.1.3 Class S 5.4.1.3.1 Encasing
43、Where stacked weights are behind the user, they shall be encased on all sides except for a 75 mm wide gap to select weights and for the weight pin to operate (see figure 1). Stacked weights that are encased shall fulfil the following requirements: a) up to 1800 mm the encasing shall be at least 60 m
44、m higher than the upper edge of the block of weights in its highest position; or b) up to 1740 mm there shall be a horizontal distance between the encasing and the weights of at least 120 mm. Dimensions in millimetres Figure 1. Weight stack behind the user 5.4.1.3.2 Reduced encasing Where the stacke
45、d weights are at the side of the user, they shall be encased on the three sides furthest from the user. On the side adjacent to the user they need not be encased, provided that they are within the field of vision at all times during the performance of the exercise (see figure 2). Where the stacked w
46、eights are at the side of the user and the side adjacent to the user does not need to be encased, there shall be a horizontal clearance of at least 50 mm between the weight guard and the front edge of the weight, and a diagonal clearance of 120 mm minimum between the weight guard and the front corne
47、r of the weight (see figure 3). A gap of 75 mm maximum is permitted on either side to allow for selection of the weight.

Clearance dimensions Where the user adopts a supine position for the performance of the exercise (e.g. a bench press), the side adjacent to the user does not need to be encased, provided that the clea
49、rance is designed according to figure 3. Multiweight stack machines do not require guarding on the three sides furthest from the user, provided that there is a framework on these sides which prevents uncontrolled access by third parties. On the side adjacent to the user the requirements apply as in 5.4.1.3. 5.4.1.3.3 No encasing Where the stacked weights are always in front of the user and visible throughout the exercise without any important obstruction (see figure 4), weights need not be encased. NOTE. Encasing is not necessary
