The requirements of this specific standard take priority over those in the general standard.1 ScopeThis part of EN 957 specifies safety requirements for stepper, stairclimber and climber machines (hereafter called training equipment) in addition to the general safety requirements of EN 957-1 and should be read in conjunction with it.This part of EN 957 is applicable to stationary training equipment type stepper, stairclimber and climber training equipment (type 8) within classes S and H, and class A for accuracy.2 Normative referencesThis European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard onlywhen incorporated in it by amendment or revision.
