Beschichtungsstoffe und Kunststoffe - Bestimmung des Gehaltes an nichtflüchtigen Anteilen (ISO 3251:2003)
Diese Internationale Norm legt ein Verfahren zum Bestimmen des Massengehaltes an nichtflüchtigen Anteilen von Beschichtungsstoffen, Bindemitteln für Beschichtungsstoffe, Polymerdispersionen und Kondensationsharzen wie Phenolharze (Resole, Novolak-Lösungen usw.) fest.
Das Verfahren ist auch auf formulierte Polymerdispersionen, die Füllstoffe, Pigmente und sonstige Hilfsstoffe (z. B. Verdickungsmittel, Filmbilde-Hilfsmittel) enthalten, anwendbar. Damit das Verfahren für weichmacherfreie Polymerdispersionen und Kautschuklatices anwendbar ist, muss der nichtflüchtige Rückstand (im Wesentlichen bestehend aus dem Polymermaterial und kleinen Mengen von Hilfsstoffen, wie z. B. Emulgatoren, Schutzkolloiden, Stabilisatoren, Lösemitteln, die als Filmbilde-Hilfsmittel und - insbesondere bei Kautschuklatex-Konzentrat - als Konservierungsmittel zugegeben werden) unter den Prüfbedingungen chemisch stabil sein. Bei weichmacherhaltigen Proben schließt der Rückstand, laut Definition, gewöhnlich den Weichmacher mit ein.
ANMERKUNG 1 Der Gehalt an nichtflüchtigen Anteilen eines Produktes ist keine absolute Größe, sondern hängt von der bei der Prüfung angewendeten Temperatur und der Prüfdauer ab. Bei der Anwendung dieses Verfahrens werden folglich nur relative Werte und nicht die wahren Werte für den Gehalt an nichtflüchtigen Anteilen erhalten, bedingt durch Lösemittelretention, thermische Zersetzung und Verdunstung niedermolekularer Anteile. Das Verfahren ist deshalb in erster Linie für die Prüfung aufeinanderfolgender Lieferungen des gleichen Produktes gedacht.
ANMERKUNG 2 Dieses Verfahren ist geeignet für synthetische Kautschuklatices, wenn die Trocknung während der entsprechenden Zeitspanne als angemessen angesehen wird (ISO 124 schreibt eine Trocknungszeit vor, bei der der Massenverlust einer Probe von 2 g nach aufeinanderfolgenden Trocknungsintervallen weniger als 0,5 mg beträgt).

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 3251 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 10,
Test methods for binders for paints and varnishes, in collaboration with ISO/TC 45, Rubber and rubber
products, as well as ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materials, and Subcommittee
SC 12, Thermosetting materials.
This third edition cancels and replaces the second edition (ISO 3251:1993) and, in addition, ISO 1625:1998
and ISO 8618:1995. During the revision and combination of these International Standards, the procedures
used for determining the non-volatile-matter content of polymer dispersions and liquid phenolic resins were
integrated into the procedure used in ISO 3251. The period of heating, temperature and test-portion mass
used for the various types of product were not changed.

INTERNATIONAL STANDARD ISO 3251:2003(E)
Paints, varnishes and plastics — Determination of non-volatile-
matter content
1 Scope
This International Standard specifies a method for determining the non-volatile-matter content by mass of
paints, varnishes, binders for paints and varnishes, polymer dispersions and condensation resins such as
phenolic resins (resols, novolak solutions, etc.).
The method is also applicable to formulated dispersions containing fillers, pigments and other auxiliaries (e.g.
thickeners and film-forming agents). For the method to be usable for unplasticized polymer dispersions and
rubber latices, the non-volatile residue (which consists essentially of the polymeric material and of small
quantities of auxiliaries such as emulsifiers, protective colloids, stabilizers, solvents added as film-forming
agents and — especially for rubber latex concentrate — preserving agents) has to be chemically stable under
the test conditions. For plasticized samples, the residue, by definition, normally includes the plasticizer.
NOTE 1 The non-volatile-matter content of a product is not an absolute quantity but depends upon the temperature
and period of heating used for the determination. Consequently, when using this method, only relative and not true values
of the non-volatile-matter content are obtained owing to solvent retention, thermal decomposition and evaporation of low-
molecular-mass constituents. The method is therefore primarily intended for testing different batches of the same type of
product.
NOTE 2 This method is suitable for synthetic rubber latices provided heating for a specific period of time is considered
appropriate (ISO 124 specifies heating until the loss in mass of a 2 g test portion following successive periods of heating is
less than 0,5 mg).
NOTE 3 In-house methods for determining non-volatile matter often include drying with infrared or microwave radiation.
