ÖNORM EN 14617-13

This European Standard covers the determination of DC insulation resistance, 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 also be used as an indirect measure of some properties of agglomerated stone products (see Annex A - informative). Volume resistance and resistivity test method and the corresponding electrical conductance and conductivity of specimens of agglomerated stone products are also included (see Annex C - informative).
