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.
