f toeboards, there could be circumstances where this is insufficient and additional measures, which are beyond the scope of this document, will need to be taken. Classes specified in this standard are intended to cater for the varied requirements appropriate for different uses. It is important that the structure to which temporary edge protection is attached can support the forces that the system is designed for. EN 13374:2020 (E) 5 `,``,``,`,`,`,` 1 Scope This European Standard specifies the requirements and test methods for temporary edge protection systems for use during construction or maintenance of buildings and other structures. This standard applies to edge protection systems for flat and inclined surfaces and specifies the requirements for three classes of temporary edge protection. For edge protection systems with an arrest function (. falling or sliding down a sloping roof) this standard specifies requirements for energy absorption. This standard includes edge protection systems, some of which are fixed to the structure and others, which rely on gravity and friction on flat surfaces. This standard does not provide requirements for edge protection systems intended for:  Protection against impact from vehicles or from other mobile equipment,  Protection from sliding down of bulk loose materials, snow etc.,  Protection of the general public from falling. This standard does not apply to side protection systems on scaffolds. 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 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 when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). prEN 741, Couplers, spigot pins and baseplates for use in falsework and scaffolds — Part 1: Couplers for tubes — Requirements and test methods.
