Describes two methods of exposure. In method A, the material is exposed under glass to natural light. In method B, the material is exposed to direct artificial light. The test sample and the agreed reference pigment are each dispersed in the same agreed binder. The dispersions are applied to a substrate and dried; they are then exposed to natural daylight with protection from rain (method A) or to artificial light (method B) under specified conditions. The resistance to light is assessed by comparing the change in colour of the test sample to that of the agreed reference pigment. Cancels and replaces the first edition ISO 787/15-1973.
Allgemeine Prüfverfahren für Pigmente und Füllstoffe - Teil 15: Vergleich der Beständigkeit bei Belichtung von Buntpigmenten ähnlichen Typs (ISO 787-15:1986)
Dieser Teil von ISO 787 beschreibt ein allgemeines Prüfverfahren zur Bestimmungder Beständigkeit bei Belichtung von zwei ähnlichen Buntpigment-Proben (vereinbartes Bezugspigment und Probe). Es werden zwei Belichtungsverfahren beschrieben. Bei Verfahren A wird das Material unter Glas mit natürlichem Tageslicht belichtet, bei Verfahren B direkt mit künstlichem Licht.
Méthodes générales d'essai des pigments et matières de charge - Partie 15: Comparaison de la résistance à la lumière des pigments colorés de types semblables (ISO 787-15:1986)
La présente partie de l'ISO 787 décrit une méthode générale d'essai pour la comparaison de la résistance à la lumière de deux échantillons de pigments colorés de types semblables (pigment de référence agréé et échantillon pour essai). Deux méthodes d'exposition sont décrites. Dans la méthode A, le matériau est exposé sous verre à la lumière naturelle. Dans la méthode B, le matériau est exposé directement à une lumière artificielle.
NOTE -- Chaque fois que l'une de ces méthodes générales (A ou B) est applicable pour un pigment donné, il devra simplement être fait référence à la méthode appropriée dans la Norme internationale relative à ce pigment, en indiquant toutes les modifications de détail qui peuvent être nécessaires en raison des propriétés spéciales du produit. 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 différente pour la comparaison de la résistance à la

Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards bodies (IS0 member bodies). The work of preparing International
Standards is normally carried out through IS0 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, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the IS0 Council. They are approved in accordance with IS0 procedures requiring at
least 75 % approval by the member bodies voting.
.
International Standard IS0 787/15 was prepared by Technical Committee ISO/TC 35,
Faints and varnishes.
This second edition cancels and replaces the first edition (IS0 787/XV-19731,
clauses 0, 2, 3, 4, 6, 7 of which have been technically revised.
Users should note that all International Standards undergo revision from time to time
and that any reference made herein to any other International Standard implies its
latest edition, unless otherwise stated.

IS0 787/15-1986 (El
The purpose of this International Standard is to establish a series of general test
methods for pigments and extenders which are suitable for all or many of the individual
pigments and extenders for which specifications might be required. In such cases, a
cross-reference to the general method should be included in the International Standard
relating to that pigment or extender, with a note of any detailed modifications which
might be needed in view of the special properties of the product in question.
Technical Committee ISO/TC 35, Paints and varnishes, decided that all the general
methods should be published as they become available, as parts of a single Inter-
national Standard, in order to emphasize the relationship of each to the whole series.
The Technical Committee also decided that, where two or more procedures were wide-
ly used for determining the same or a similar characteristic of a pigment or extender,
there would be no objection to including more than one of them in the IS0 series. In
such cases it will, however, be essential to state clearly in a specification which method
is to be used and, in the test report, which method has been used.
Parts of the series already published are as follows:
Part 1 : Comparison of colour of pigments
Part 2 : Determination of matter volatile at 105 OC
Part 3 : Determination of matter soluble in water - Hot extraction method
Part 4 : Determination of acidity or alkalinity of the aqueous extract
Part 5 : Determinati
