General methods of test for pigments and extenders - Part 17: Comparison of lightening power of white pigments (ISO 787-17:2019)

This document specifies a general method of test for comparing the lightening (reducing) power of a
white pigment with the lightening power of an agreed sample of the same type.
Two procedures (A and B) are specified. Procedure A is quicker than procedure B and is suitable for
testing one sample of pigment; procedure B is better for testing several samples, and especially if a
pigment of unknown lightening power is being tested.

Allgemeine Prüfverfahren für Pigmente und Füllstoffe - Teil 17: Vergleich des Aufhellvermögens von Weißpigmenten (ISO 787-17:2019)

Dieses Dokument legt ein allgemeines Prüfverfahren zum Vergleichen des Aufhellvermögens eines
Weißpigmentes mit dem Aufhellvermögen einer vereinbarten Probe desselben Typs fest.
Es werden zwei Vorgehensweisen (A und B) festgelegt. Vorgehensweise A ist schneller als Vorgehensweise B
und eignet sich für die Prüfung einer Pigmentprobe; Vorgehensweise B ist besser für die Prüfung mehrerer
Proben, und besonders wenn ein Pigment mit unbekanntem Aufhellvermögen geprüft wird.

Méthodes générales d'essai des pigments et matières de charge - Partie 17: Comparaison du pouvoir éclaircissant des pigments blancs (ISO 787-17:2019)

Le présent document spécifie une méthode générale d'essai pour comparer le pouvoir éclaircissant des pigments blancs au pouvoir éclaircissant d'un échantillon agréé de même type.
Deux modes opératoires (A et B) sont spécifiés. Le mode opératoire A est plus rapide que le mode opératoire B et convient pour essayer un échantillon de pigment. Le mode opératoire B est préférable pour essayer plusieurs échantillons et particulièrement si un pigment de pouvoir éclaircissant inconnu doit être essayé.

Splošne metode preskušanja pigmentov in polnil - 17. del: Primerjava moči posvetlitve belih pigmentov (ISO 787-17:2019)

Ta dokument določa splošno metodo preskušanja za primerjavo moči posvetlitve (reduciranja) belega pigmenta s primerjavo moči posvetlitve dogovorjenega vzorca iste vrste.
Opisana sta dva postopka (A in B). Postopek A je hitrejši od postopka B in je primeren za
preskušanje enega vzorca pigmenta; postopek B je boljši za preskušanje več vzorcev, še posebej
za preskušanje pigmenta neznane moči posvetlitve.

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.

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