25、16 EN 397:1995 BSI 03-2001 3 1 Scope This European Standard specifies physical and performance requirements, methods of test and marking requirements for industrial safety helmets. The mandatory requirements apply to helmets for general use in industry. Additional optional performance requirements a
26、re included to apply only where specifically claimed by the helmet manufacturer. Industrial safety helmets are intended primarily to provide protection to the wearer against falling objects and consequential brain injury and skull fracture. 2 Normative references This European Standard incorporates
27、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 Sta

31、ss The complete assembly that provides a means: a) of maintaining the helmet in position on the head; and/or b) of absorbing kinetic energy during an impact. NOTEA harness includes a headband and napestrap and may also include the items defined in 3.5.3 to 3.5.6. 3.5.1 headband the part of the harne
32、ss completely or partly surrounding the head above the eyes at approximately the largest horizontal circumference of the head NOTEThe headband may include a nape strap. 3.5.2 nape strap the adjustable strap that fits behind the head below the plane of the headband NOTEA nape strap may be an integral
