Licensed copy:PONTYPRIDD COLLEGE, 05/01/2008, Uncontrolled Copy, BSI ? EN 12407:2007 (E) 4 Introduction A petrographic description of natural stone is
16、important not only for the purposes of petrographic classification but also in order to highlight features influencing its chemical, physical and mechanical behaviour. In the same way the determination of the stone s origin could be necessary (e.g. in the case of restoration of historical monuments)
17、. It is therefore essential to characterize the natural stones not only from the point of view of their mineral components and of their fabric and structure but also in terms of any features as: colour, presence of veins, of fossils, of discontinuities, etc. To ensure that the petrographic classific
18、ation is objective, it is essential that the characterization of the material be, as far as possible, quantitative. Licensed copy:PONTYPRIDD COLLEGE, 05/01/2008, Uncontrolled Copy, BSI ? EN 12407:2007 (E) 5 1 Scope This European Standard specifies methods for making technical petrographic descriptio

Although chemical and physical methods of analysis are required for petrographic classification of some stone types, these methods will not be described in this sta
