EN 14617-13:2005

This test method covers the determination of dc insulation resistance, volume resistance and resistivity, as well as surface resistance and resistivity, and the corresponding electrical conductance and conductivity, of specimens of agglomerated stone products conforming to the definition reported in EN 14618. These products are usually made by stone aggregates bound via either resin and filler or cement and water (paste components) or a mixture of polymer/cement and related addition (such as reinforcing fibres, electrically insulating/conducting fillers, etc.). Resistivity/conductivity may be also used as an indirect measure of some properties of agglomerated stones products (see Annex A).
