General Information

Overview
EN 14617-13:2013 (CEN) specifies standardized test methods for determining electrical resistivity and related properties of agglomerated stone products. The standard covers DC insulation resistance, surface resistance and surface resistivity, and their reciprocals - surface conductance/conductivity - plus, in an informative annex, volume resistance/volume resistivity and corresponding conductivity. It applies to agglomerated stones made from stone aggregates bound with resin/filler, cement/paste, or polymer/cement blends and containing additives (fibres, conductive/insulating fillers, etc.).
Key topics and technical requirements
- Measurement principle: DC current measurement across specimens; resistivity/conductivity calculated from specimen and electrode dimensions.
- Specimen preparation and sampling: Representative sampling; at least five specimens; surfaces honed or polished; specimen shapes suitable for three‑terminal electrode assemblies.
- Specimen conditioning: Tests may be run on room‑conditioned specimens (23 ± 2 °C, 50 ± 10 % RH) or on dried specimens (oven dry at 50 ± 2 °C to constant mass, cooled in desiccator).
- Electrode system and equipment:
- Preferred three‑terminal (guarded) flat circular electrode configuration for surface measurements; two‑terminal acceptable for simple insulation resistance.
- Effective contact achieved via conducting coatings (graphite, metal spray) or semiconducting sheets; electrometers or voltmeter‑ammeter setups recommended.
- Procedure and parameters: Typical electrification time 60 s and an applied DC voltage of about 100 V (adjustable by resistivity and thickness); measure geometry (electrode diameter, guard gap, specimen thickness) and calculate surface resistivity.
- Results and statistics: Calculate mean values and perform statistical evaluation (Annex B) to report standard deviation and coefficient of variation. Annex C gives informative guidance on volume resistivity testing.
Practical applications and users
EN 14617-13:2013 is used for:
- Quality control and acceptance testing of manufactured agglomerated stone (worktops, tiles, cladding).
- Product development and R&D where resistivity indicates effects of fillers, binders or moisture.
- Safety and functional assessment for antistatic or conductive surface requirements in laboratories, electronics facilities, or public spaces.
- Material specification and procurement by manufacturers, testing laboratories, architects and specifiers who need consistent, comparable electrical-property data.
Typical users include test laboratories, manufacturers of engineered stone, material scientists, façade/fit-out contractors, and compliance officers.

4 Terms and definitions and symbols 4.1 insulation resistance
Ω Ω = ohm insulation resistance between two electrodes that are in electrical contact with an agglomerated stone specimen, calculated as the ratio of the direct voltage applied to the electrodes to the total current flowing between them Note 1 to entry: It is dependent upon the shape and size as well as the volume and surface resistance of the specimen. 4.2 surface resistance
Rs (Ω) surface resistance between two electrodes that are in electrical contact with the surface of an agglomerated stone specimen, calculated as the ratio of the direct voltage applied to the electrodes to that portion of the current between them which is primarily distributed on the specimen surface and a thin material layer beneath the specimen surface
Note 1 to entry: Surface conductivity cannot be accurately known, only conventionally, because more or less volume contribution is usually involved in the measurement, depending on the nature of the specimen and environment. 4.3 surface resistivity
ρs (Ω) surface resistivity of the agglomerated stone material, which is calculated as the ratio of the potential gradient parallel to the current direction along its surface to the current per unit width of the surface SIST EN 14617-13:2013
γs (Ω-1) reciprocal of the surface resistivity 4.5 volume resistance
Rv (Ω) volume resistance between two electrodes that are in electrical contact with a specimen, calculated as the ratio of the direct voltage applied to the electrodes to that portion of the current between them that flows only through the volume of the specimen 4.6 volume resistivity
ρv (Ω·m) volume resistivity of the agglomerated stone material, which is calculated as the ratio of the potential gradient, parallel to the current direction in the material, to the current density
EXAMPLE The charge carriers flow through the specimen, charge flowing in the unit time across the unit surface area normal to the current direction. 4.7 volume conductivity
γv (Ω-1·m-1 = S/m S = siemens) reciprocal of the volume resistivity 5 Sampling and test specimen preparation Sampling is not the responsibility of the test laboratory, unless otherwise agreed. It shall be appropriate to agglomerated stone consignment. Whenever possible, the random sampling method shall be used. Test specimens shall, however, be representative of the agglomerated stone sample and can be directly obtained from laboratory moulding and curing according to a detailed procedure (properly described in the test report) and/or core samples taken "in situ" and cut to proper size for the measuring apparatus. The surfaces shall be honed or polished. The test specimen may have any practical shape allowing the use of a proper three terminal electrodes system, according to the electrode assembly schematically shown in Figure 1 for flat test specimens. Sheet specimens like those illustrated in Figure 1 should exhibit a thickness exceeding by 20 % the largest stone fragments size used in the agglomerated stone, and a diameter of 20 mm to 160 mm according to the resistivity of the tested material. At least five test specimens shall be selected by sampling. 6 Specimen conditioning Measurements shall be made on either room-conditioned (23 ± 2) °C and (50 ± 10) % R.U. or dried specimens. In the first case, specimens shall be measured after proper conditioning (24 h at least) in the measuring environment according to other existing standard conditioning procedures. In the latter case, specimen should be dried to constant weight in a circulating-air oven at (50 ± 2) °C (i.e. difference < 0,1 % mass by consecutive weighing/ 24 h). After removing from the oven, specimens shall be cooled to room temperature in a dessicator under anhydrous atmosphere (anhydrous calcium chloride can be used) or in a vacuum enclosure until testing.
