18、Committee CEN/TC 53 “Temporary worksequipment“, 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 orby endorsement, at the latest by February 2003, and conflicting national standards shall be wi
19、thdrawn at the latestby February 2003.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy,
20、Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,Sweden, Switzerland and the United Kingdom.EN 13331, Trench lining systems consists of the following parts:Part 1: Product specifications.Part 2: Assessment by calculation or test.These standards are to be read in conjunction with prEN 12811-2
21、and prEN 12811-3 Temporary works equipment-Scaffolds.BS EN 13331-1:2002EN 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
22、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
23、 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
24、 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 her
25、eafter. 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.
