General methods of test for pigments and extenders - Part 5: Determination of oil absorption value (ISO/DIS 787-5:2025)

The oil absorption value is required to be compared with the value determined at the same time on an agreed sample of the product. The principle of the method is based on addition of linseed oil from a burette to the test portion. After each addition, rub the oil into the product until conglomerates are formed. Cease the addition of oil when a paste of smooth consistency has been formed. It should just spread without cracking or crumbling. Read the burette and note the quantity of oil used. The result is expressed in millilitres of oil per 100 g of product or in grams of oil per 100 g of product. - Cancels and replaces Part 5 of ISO/R 787-1968.

Méthodes générales d_essai des pigments et matières de charge — Partie 5: Détermination de la prise d_huile (ISO/DIS 787-5:2024)

La présente partie de l'ISO 787 spécifie une méthode générale d'essai pour la détermination de la prise d'huile d'un pigment ou d'une matière de charge. La prise d'huile est généralement nécessaire pour être comparée avec la valeur déterminée au même moment sur un échantillon agréé de produit.
NOTE -- Chaque fois que cette méthode générale est applicable pour un pigment ou une matière de charge donné(e), il devra simplement y être fait référence dans la Norme internationale relative à ce pigment ou cette matière de charge, et il devra être mentionné, dans une note, toutes les modifications de détail qui peuvent être nécessaires en raison des propriétés spéciales du produit considéré. Ce n'est que dans le cas où une telle méthode générale ne serait pas applicable à un produit particulier, qu'il deviendrait nécessaire de spécifier une méthode spéciale pour la détermination de la prise d'huile.

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).
