General methods of test for pigments and extenders - Part 11: Determination of tamped volume and apparent density after tamping (ISO 787-11:1981)
The test is carried out by the following procedure: drying of the sample in the oven at (105 2) °C, passing the dried sample through the sieve and transferring it of the graduated measuring cylinder, but so that no air pockets are formed. Weighing of the cylinder and of the sample. Placing of the cylinder in the tamping volumeter and tamping it in steps of approximately 1250 revolutions until the difference between two successive steps of tamping is less than 2 ml. Calculation of results. - Cancels and replaces ISO Recommendation ISO/R 787/11-1970.
Allgemeine Prüfverfahren für Pigmente und Füllstoffe - Teil 11: Bestimmung des Stampfvolumens und der Stampfdichte (ISO 787-11:1981)
Dieser Teil von ISO 787 legt ein allgemeines Prüfverfahren zur Bestimmung des Stampfvolumens und der Stampfdichte einer Pigment- oder Füllstoffprobe fest. Anmerkung: Wenn dieses allgemeine Verfahren für ein bestimmte Pigment oder einen Füllstoff anwendbar ist, braucht nur ein Querverweis in die Internationale Norm für dieses Pigment oder den Füllstoff aufgenommen werden, mit einem Hinweis auf jede Abweichung, die im Hinblick auf die speziellen Eigenschaften des Produktes erforderlich ist.
Méthodes générales d'essai des pigments et matieres de charge - Partie 11: Détermination de la masse volumique apparente et de la masse apparente apres tassement (ISO 787-11:1981)
La présente partie de l'ISO 787 spécifie une méthode générale d'essai pour la détermination du volume massique et de la masse volumique apparents après tassement d'un échantillon de pigment ou de matière de charge.
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 du volume massique et de la masse volumique apparents après tassement.

Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards institutes (IS0 member bodies). The work of developing Inter-
national Standards is carried out through IS0 technical committees. Every member
body interested in a subject for which a technical committee has been set up 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.
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.
International Standard IS0 787/11 was developed by Technical Committee
ISO/TC 35, Paints and varnishes, and was circulated to the member bodies in
January 1980.
It has been approved by the member bodies of the following countries :
Australia Ireland Romania
Austria Israel South Africa, Rep. of
Brazil Italy Spain
China Kenya Sweden
Egypt, Arab Rep. of Korea, Rep. of Switzerland
France Netherlands United Kingdom
Germany, F. R. New Zealand USSR
Hungary Norway
India Poland
No member body expressed disapproval of the document.
This International Standard cancels and replaces IS0 Recommendation
R 787/11-1970, of which it constitutes a technical revision.

SIST EN ISO 787-11:1997
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 Interna-
tional 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
widely used for determining the same or a similar characteristic of a pigment or ex-
tender, 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 : Determination of oil absorption value
Part 6 : Determination of residue on sieve - Oil method
Part 7 : Determination of residue on sieve - Water method - Manual procedure
Part 8 : Determination of matter soluble in water - Cold extraction method
Part 9 : Determination of pH value of an aqueous suspension
Part 10 : Determination of density - Pyknometer method
Part 11 : Determination of tamped volume and apparent density after tamping
Part 13 : Determination of water-soluble sulphates, chlorides and nitrates
Part 14 : Determination of resistivity of aqueous extract
Part 15 : Comparison of resistance of coloured pigments of similar types to light
from a specified light source
Part 16 : Comparison of relative tinting strength (or equivalent colouring value) and
colour on reduction in linseed stand oil using the automatic muller
Part 17 : Comparison of lightening power of white pigments
Part 18 : Determination of residue on sieve - Water method - Mechanical
flushing procedure
Part 19 : Determination of water-soluble nitrates - Salicylic acid method
Part 20 : Comparison of ease of dispersion - Oscillatory shaking method
Part 21 : Comparison of heat stability of pigments using a stoving medium
Part 22 : Comparison of resistance to bleeding of pigments
Part 23 : Determination of density (using a centrifuge to remove entrained air)
Part 24 : Determination of relative tinting strength of coloured pigments and
