SIST EN 14617-13:2013

• Abstract:

  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).

SIST EN 14617-13:2013 is the Slovenian edition of EN 14617-13:2013 from CEN. It specifies test methods for measuring DC insulation resistance, surface resistance and resistivity, and the corresponding electrical conductance and conductivity of agglomerated stone specimens. The standard is meant for testing agglomerated stone products defined in EN 14618, including materials made with stone aggregates bound by resin, cement, or mixed polymer/cement systems.

What does SIST EN 14617-13:2013 specify?

SIST EN 14617-13:2013 specifies how to prepare, condition, measure, calculate and report electrical resistivity-related properties of agglomerated stone. It focuses on DC measurements on test specimens and explains the surface method, with an additional informative method for volume measurements.

Annex	What it covers
Annex A	DC electrical conduction and polarisation phenomena in insulating materials
Annex B	Statistical evaluation of test results
Annex C	Determination of DC volume resistance and resistivity, and the corresponding conductance and conductivity

The document is organized into Scope, Normative references, Principle, Terms and definitions and symbols, Sampling and test specimen preparation, Specimen conditioning, Electrode system and measuring equipment, Procedure, Expression of results, Report, and informative Annexes A to C. That structure matters in practice because it tells the reader where to find the specimen rules, the measuring setup, the calculation approach, and the reporting items.

What are the key requirements of SIST EN 14617-13:2013?

SIST EN 14617-13:2013 is mainly a laboratory test method standard. The most important requirements are about representative sampling, controlled conditioning, the electrode arrangement, fixed measurement conditions, and complete reporting.

• Sampling and specimen preparation, Clause 5 - Sampling is normally not the laboratory’s responsibility unless agreed otherwise, but the sample must represent the consignment. At least five test specimens are selected, and surfaces are honed or polished. In practice, this means the result should reflect the product batch, not a single convenient piece.

• Specimen shape and size, Clause 5 - Specimens may be made from laboratory moulding and curing or from in situ core samples cut to size, and the geometry must suit a proper three-terminal electrode system. For flat specimens, the thickness should exceed the largest stone fragment size by 20 %, and the diameter is tied to the material resistivity. This matters because geometry affects the measured resistance.

• Conditioning, Clause 6 - Measurements are made either on room-conditioned specimens at 23 °C and 50 % relative humidity, after at least 24 h conditioning, or on dried specimens. Dried specimens are brought to constant weight, then cooled in a dry environment or vacuum before testing. This matters because moisture changes electrical behavior.

• Electrodes and equipment, Clause 7 - Surface measurements use flat circular electrodes in a three-terminal configuration; the guard electrode may be omitted only when surface leakage is negligible. A two-terminal arrangement is used only for insulation resistance. In practice, the electrode choice controls whether surface leakage influences the result.

• Procedure, Clause 8 - At least five specimens are measured, dimensions are taken, and the electrical measurement is made in a controlled atmosphere. Unless otherwise specified, the electrification time is 60 s and the applied DC voltage is 100 V or higher, depending on thickness and resistivity. This gives comparable results across tests.

• Expression of results, Clause 9 - Surface resistivity and conductivity are calculated from the measured resistance and specimen geometry, and the standard also gives a volume-resistance method in Annex C. The standard asks for mean values and, where appropriate, statistical treatment such as standard deviation and coefficient of variation. That helps users compare batches and assess scatter.

• Reporting, Clause 10 - The test report must identify the standard, the laboratory, the client, the specimen details, conditioning, measuring conditions, equipment, applied voltage, time of voltage application, results, deviations and responsible signatories. This makes the result traceable for quality control, disputes, or product documentation.

What terms does SIST EN 14617-13:2013 define?

• Insulation resistance - The DC resistance measured between two electrodes in contact with the specimen, based on applied voltage divided by total current.
• Surface resistance - The resistance associated mainly with current flowing on the surface and a thin layer beneath it.
• Surface resistivity (ρs) - The material property calculated from surface resistance and specimen geometry.
• Surface conductivity (γs) - The reciprocal of surface resistivity.
• Volume resistance (Rv) - The resistance due to current flowing only through the specimen volume.
• Volume resistivity (ρv) - The material property calculated from volume resistance and specimen geometry.
• Volume conductivity (γv) - The reciprocal of volume resistivity.

Who uses SIST EN 14617-13:2013?

This standard is used by test laboratories, agglomerated stone manufacturers, and quality control teams that need to measure electrical behavior as part of product characterization. It is also relevant to specifiers, buyers, and technical managers who need to compare materials for building and architectural use, especially where moisture, static charge, electrical insulation, or conductive fillers matter. Annex C is particularly relevant when volume properties are of interest, such as for some raised access floor applications.

What changed in SIST EN 14617-13:2013 from the previous edition?

SIST EN 14617-13:2013 supersedes EN 14617-13:2005. The foreword states that Clauses 6, 7, 8, 9 and 10 were modified, and a new informative Annex C was added.

What does the SIST EN 14617-13:2013 document contain?

SIST EN 14617-13:2013 contains a surface-resistance test method based on DC measurement, with figures for the three-terminal electrode arrangement and the voltmeter-ammeter setup. It also includes calculation guidance for flat circular specimens and an informative statistical annex with mean value, standard deviation, coefficient of variation, and a quantile factor table. Annex A explains why time, humidity and voltage matter for insulating materials, while Annex C gives an informative volume-resistance method using the same general specimen preparation and conditioning approach.

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.
