29、s.5Safety requirements5.1GeneralDepending on the design of the piece of training equipment the following requirements shall apply as appropriate.Licensed Copy: London South Bank University, London South Bank University, Sun Mar 19 03:03:20 GMT 2006, Uncontrolled Copy, (c) BSI5.2Loading5.2.1Intrinsic
30、 loadingEach piece of equipment loaded with the users bodymass shall withstand a force Ffor class H2,5 times the bodymass (100 kg) without breakage,for class S2 times the bodymass (100 kg) without permanent deformation.When tested according to 6.2, supports (e. g. load bearing surfaces) shall not be
31、 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 of 4 times the bodymass is applied.5.2.2Extrinsic loading5.2.2.1Class HWhen tested according to 6.3 and
32、loaded with the users bodymass and/or reaction forces or moments of the user, each piece of equipment shall withstand without breakage a load F according to equation (1):F(N) = Gk (kg) + 1,5 G (kg) 2,5 9,81m/s(1)whereGis the maximum load in kilograms indicated by the manufacturer (see clause 10 of E

36、ter the test, supports (load bearing surfaces) shall not be deformed by more than f = 1/100, cantilever supports (cantilever surfaces) by not more than f = 1/150and other dimensions by not more than 1 %.If greater than manufacturers maximum stated load, the equipment shall be capable of accepting a
37、minimal torque load as specified in Table 1, throughout the range of movement of each exercise for which the equipment is designed. The training equipment shall not break when a static load according to equation (2) with a safety coefficient of 4 is applied.5.3Endurance loadWhen tested according to
38、6.4, the training equipment shall be capable of normal function.When the training equipment consists of 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,
39、 these can be replaced before each separate test.5.4Stacked weights5.4.1Access to squeeze and/or shear points5.4.1.1GeneralThe 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 cl
40、oser than 60 mm during movement to any part ofthe equipment or the ground.5.4.1.2Class HThis 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; orb)by locking the machine to prevent moving of the s

Stacked weights that are encased shall fulfill the following requirement: up to 1 800 mm the encasing
