General methods of test for pigments and extenders - Part 14: Determination of resistivity of aqueous extract (ISO 787-14:2019)
This document specifies a general method of test for determining the electric resistivity (specific electric resistance) or the specific electric conductivity, respectively, of the aqueous extract of a pigment. The method is applicable to all pigments and extenders, except pigments that are soluble in water.
The resistivity of the aqueous extract of a pigment is considered as a property independent of the amount of water-soluble matter. If agreed, a cold extraction method can be used.

Méthodes générales d'essai des pigments et matières de charge - Partie 14: Détermination de la résistivité de l'extrait aqueux (ISO 787-14:2019)
Le présent document spécifie une méthode générale d'essai pour déterminer la résistivité électrique (résistance électrique spécifique) ou la conductivité électrique spécifique de l'extrait aqueux d'un pigment. La méthode est applicable à tous les pigments et matières de charge, à l'exception des pigments solubles dans l'eau.
La résistivité de l'extrait aqueux d'un pigment est considérée comme une propriété indépendante de la quantité de matières solubles dans l'eau. Si un accord a été conclu en ce sens, une méthode par extraction à froid peut être utilisée.
Splošne metode preskušanja pigmentov in polnil - 14. del: Določevanje specifične upornosti vodnega ekstrakta (ISO 787-14:2019)
Ta dokument določa splošno metodo preskušanja za določevanje električne upornosti (specifične električne upornosti) oziroma specifične električne prevodnosti vodnega ekstrakta pigmenta. Metoda se uporablja za vse pigmente in polnila, ki so topni v vodi.
Upornost vidnega ekstrakta pigmenta se obravnava kot lastnost, neodvisna od količine v vodi topne snovi. V primeru dogovora se lahko uporablja metoda hladne ekstrakcije.

Overview
SIST EN ISO 787-14:2019 outlines a standardized method for determining the electric resistivity (or specific electric conductivity) of aqueous extracts of pigments and extenders. Developed by the International Organization for Standardization (ISO) and adopted by the Slovenian Institute for Standardization (SIST), this document ensures the uniform testing of electrical properties in pigment samples, except where pigments are water-soluble. The test delivers consistent and reliable results that are crucial for product comparison, quality control, and compliance across the paints, coatings, plastics, and pigment manufacturing industries.
Key Topics
- Scope of Application: The method applies to all pigments and extenders excluding those soluble in water. The test procedure accommodates cold extraction upon agreement between parties.
- Measurement Principles: Focuses on resistivity (specific electric resistance) or its reciprocal, specific electric conductivity, as measured in the aqueous extract of a pigment.
- Independence from Soluble Content: The resistivity measured is considered an intrinsic property of the pigment, not directly linked to the quantity of water-soluble substances.
- Standardized Procedure: Includes steps for sample preparation, wetting with ethanol if required, extraction (by heating or at room temperature), filtration, and measurement using a calibrated conductivity meter.
- Test Reporting: Ensures thorough documentation of test conditions, handling of deviations, and identification of all sample and testing parameters.
Applications
The standardized procedure in ISO 787-14:2019 is widely used in:
- Paints and Coatings Manufacturing: Accurate measurement of pigment resistivity supports the development of high-performance coatings by informing decisions on pigment selection and compatibility.
- Quality Control: Enables manufacturers and laboratories to verify the consistency of pigment batches, supporting stricter quality standards and regulatory compliance.
- Product Development: R&D teams utilize resistivity data to optimize pigment formulations for specific electrical or dispersive properties in end-use applications.
- Pigment and Extender Production: Producers use the method to certify product quality, fulfill client specifications, and benchmark products internationally.
- Comparative Analysis: Provides a consistent basis for comparing pigments and extenders from different sources or production processes.
