22、nd United Kingdom. EN 14120:2003+A1:2007 (E) 4 Introduction Roller sports are all the pastimes and competitions in which roller sports equipment is used. This equipment includes for example roller skates, inline skates and skateboards. The users range from small children to adults of all ages. The m

23、ain threat to most roller sports equipment users is an impact with the surface and with obstacles which may cause physical injuries. Wrist, palm, knee and elbow protectors for users of roller sports equipment are intended to protect the wearer against abrasion, bruises and fractures. Protectors will

24、 not necessarily prevent all injuries in roller sports accidents. EN 14120:2003+A1:2007 (E) 5 1 Scope This European Standard specifies the requirements and test methods for ergonomics, innocuousness, comfort, restraint, strength, abrasion, impact performance as well as provisions for marking and ins

25、tructions supplied by the manufacturer for wrist, palm, knee and elbow protectors (hereinafter referred to as protectors) for all users of roller sports equipment. It does not apply to protectors used in roller sports hockey. 2 Normative references This European Standard incorporates by dated or und

26、ated 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 only whe
