Paints and varnishes - Determination of electrical conductivity and resistance (ISO 15091:2012)
This International Standard specifies a method for determining the electrical conductivity and the electrical resistance of coating materials. The conductivity is usually measured for water-borne paints and varnishes, including electrodeposition coating materials, and the resistance is usually measured for solvent-borne paints and varnishes. If required, the resistivity of the coating material is calculated from either of these measurements. The method is applicable to products having a conductivity less than 5 μS/cm, corresponding to a resistivity greater than 200 kΩ.cm. The conductivity of coating materials influences their processibility in the presence of an electric field. This is particularly important for electrodeposition paints and coating materials which are processed electrostatically.
Beschichtungsstoffe - Bestimmung der elektrischen Leitfähigkeit und des elektrischen Widerstandes (ISO 15091:2012)
Die Norm legt ein Verfahren zum Messen der elektrischen Leitfähigkeit und des elektrischen Widerstandes von Beschichtungsstoffen fest. Das Verfahren ist für Produkte mit einer Leitfähigkeit kleiner als 5 µS/cm, entsprechend einem Widerstand größer als 200 k cm.
Die spezifische elektrische Leitfähigkeit von Beschichtungsstoffen beeinflusst deren Verarbeitbarkeit im elektrischen Feld. Dies ist insbesondere von Bedeutung bei Elektrotauchlacken und Beschichtungsstoffen, die elektrostatisch verarbeitet werden.
Peintures et vernis - Détermination de la conductivité et de la résistance électriques (ISO 15091:2012)
L'ISO 15091:2012 spécifie une méthode de détermination de la conductivité et de la résistance électriques des produits de revêtement. La conductivité est généralement mesurée pour les peintures et vernis en phase aqueuse, y compris les produits de revêtement appliqués par électrodéposition, et la résistance est généralement mesurée pour les peintures et vernis en phase solvant. Si nécessaire, la résistivité du produit de revêtement est calculée à partir de l'un ou l'autre de ces mesurages. La méthode s'applique aux produits ayant une conductivité inférieure à 5 µS/cm, correspondant à une résistivité supérieure à 200 kΩ cm.
Barve in laki - Določanje električne prevodnosti in električne upornosti (ISO 15091:2012)
Ta mednarodni standard določa metodo za določanje električne prevodnosti in električne upornosti za premazna sredstva. Prevodnost se običajno meri pri barvah in lakih na vodni osnovi, vključno s premaznimi sredstvi, nanesenimi s potapljanjem in uporabo električnega toka, upornost pa se običajno meri pri raztopinskih barvah in lakih. Če je potrebno, se upornost premaznih sredstev izračuna iz ene od teh meritev. Metoda se uporablja za izdelke s prevodnostjo, manjšo od 5 μS/cm, kar ustreza upornosti, višji od 200 kΩ.cm. Prevodnost premaznih sredstev vpliva na njihovo primernost za obdelavo v prisotnosti električnega polja. To je zlasti pomembno za barve, nanesene s potapljanjem in uporabo električnega toka, in lake, ki so obdelani elektrostatično.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 15091 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9,

Paints and varnishes — Determination of electrical conductivity
and resistance
1 Scope
This International Standard specifies a method for determining the electrical conductivity and the electrical
resistance of coating materials. The conductivity is usually measured for water-borne paints and varnishes,
including electrodeposition coating materials, and the resistance is usually measured for solvent-borne paints
and varnishes. If required, the resistivity of the coating material is calculated from either of these measurements.
The method is applicable to products having a conductivity less than 5 µS/cm, corresponding to a resistivity
greater than 200 kΩ⋅cm.
The conductivity of coating materials influences their processibility in the presence of an electric field. This is
particularly important for electrodeposition paints and coating materials which are processed electrostatically.
