15、from a height including working belts“, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2002, and conflicting national standards shall be withdraw
16、n at the latest by November 2002. This document supersedes EN 355:1992. This new edition contains the old text of the standard and incorporates some urgent amendments that are intended to give additional information and clarify inconsistencies. A comprehensive revision of the standard will follow at
17、 a later stage. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s).

Energy absorbers conforming to this European Stan
20、dard are used as elements or components either integrated in a lanyard, an anchor line or a full body harness or in combination with one of them. Combinations of an energy absorber and a lanyard are sub-systems constituting one of the fall arrest systems covered by EN 363, when combined with a full
21、body harness specified in EN 361. Fall arresters are specified in EN 353-1, EN 353-2 and EN 360. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, a
22、nd the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.
