Clauses of this European Standard addressing essential requirements or other provisions of EU Directives.24
1 Scope !This European Standard specifies the requirements for the homologation of track geometry quality parameters as measured by various measuring devices fitted on track recording vehicles." These measuring devices are described in !Part 2" of the standard. This European Standard applies to all track geometry parameters including track gauge, longitudinal level, alignment, cross level (cant / superelevation) and twist. It defines each parameter and specifies the requirements for measurement, the analysis methods and the presentation of results. !Parts 3 and 4 give a description of measuring devices complying partially with this Part 1 according to the specificities of respectively track construction and maintenance machines, and manual and lightweight devices." 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). !EN 13848-2, Railway applications — Track — Track geometry quality — Part 2: Measuring systems — Track recording vehicles" ENV 13005:1999, Guide to the expression of uncertainty in measurement 3 Terms, definitions, symbols and abbreviated terms 3.1 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply (refer also to the terms and definitions described in clause 4 of this part). 3.1.1 track geometry quality assessment of excursions from the mean or designed geometrical characteristics of specified parameters in the vertical and lateral planes which give rise to safety concerns or have a correlation with ride quality 3.1.2 gauge face inside face of the running rail head 3.1.3 running table upper surface of the head of the rail 3.1.4 running surface curved surface defined by the longitudinal displacement of a straight line perpendicular to the centre-line of the track and tangential to both running tables 3.1.5 running plane plane tangential to the running surface at the point of measurement SIST EN 13848-1:2004+A1:2008
