EN 13331-1:2002 (E)4IntroductionTrench lining systems are intended to ensure the stability of vertical trench walls and to protect workers from theeffects of collapse of the trenches.Part 1 of the series deals with materials and specifications for the manufacture of trench lining systems.Part 2 of the series deals with the evaluation methods using both calculations and tests for trench lining systems.A trench lining system comprises a variety of components, which, when assembled, create trench support. Theinstruction manual provides all the necessary information on the designation and safe use of trench lining systems.1 ScopeThis European Standard specifies requirements for metallic trench lining systems assembled completely frompurpose made prefabricated components. It includes material, constructional and structural requirements.Partial safety factors for design refer to annex A.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision.
