This part of IS0 787 specifies a general method of test for
determining the oil absorption value of a sample of pigment or
extender. The oil absorption value is usually required to be
compared with the value determined at the same time on an
agreed sample of the product.
NOTE - When this general method is applicable to a given pigment or
extender, only a cross-reference to it should be included in the International
Standard relating to that pigment or extender, with a note of any
detailed modification which may be needed in view of the special properties
of the material in question. Only when this general method is
not applicable to a particular material should a special method for
determination of oil absorption value be specified.
Diese ÖNORM beschreibt eine allgemeine Prüfmethode zur Bestimmung des Ölabsorptionswertes einer Pigmentprobe oder der Probe eines Füllstoffes. Der Ölabsorptionswert wird üblicherweise benötigt zum Vergleich mit dem zur selben Zeit an einer vereinbarten Probe des Produktes bestimmten Wert.
