Paints and varnishes - Determination of electrical conductivity and resistance (ISO 15091:2019)

EN-ISO 15091 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 kO·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 15091:2019)

Dieses Dokument legt ein Verfahren zum Bestimmen der elektrischen Leitfähigkeit und des elektrischen Widerstandes von Beschichtungsstoffen fest. Bei wasserverdünnbaren Beschichtungsstoffen einschließlich Elektrotauchlacken wird üblicherweise die Leitfähigkeit gemessen und bei lösemittelverdünnbaren Be¬schichtungsstoffen üblicherweise der Widerstand. Falls gefordert, wird aus dem jeweiligen Messwert der spezifische elektrische Widerstand des Beschichtungsstoffes berechnet. Das Verfahren ist für Produkte mit einer Leitfähigkeit kleiner als 5 µS/cm, entsprechend einem spezifischen elektrischen Widerstand größer als 200 kΩ ⋅ cm anwendbar.
Die Leitfähigkeit von Beschichtungsstoffen beeinflusst deren Verarbeitbarkeit in einem elek¬trischen 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 15091:2019)

Le présent document 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.
La conductivité des produits de revêtement a un effet sur leur capacité à être mis en œuvre en présence d'un champ électrique. Cela est particulièrement important pour les peintures appliquées par électrodéposition et les produits de revêtement appliqués électrostatiquement.

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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

This document was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee

SC 9, General test methods for paints and varnishes.

This second edition cancels and replaces the first edition (ISO 15091:2012), of which it constitutes a

minor revision. The changes compared to the previous edition are as follows:

— the conductivity of the aqueous potassium chloride solution with a molality of 0,001 mol/kg has

been corrected to 146,71 µS/cm to correct a mistake in conductivity;
— the text has been editorially revised.

Any feedback or questions on this document should be directed to the user’s national standards body. A
