Paints and varnishes - Determination of the percentage volume of non-volatile matter - Part 2: Method using the determination of non-volatile-matter content in accordance with ISO 3251 and determination of dry film density on coated test panels by the Archimedes principle (ISO 3233-2:2019)

This Standard specifies a method for determining the non-volatile matter by volume (NVV) of coating materials by determining the practical dry-film density. This method determines the volume percentage of non-volatile matter in paints, varnishes and related products by measuring the density of a dry coating for any specified temperature range and period of drying or curing. The non-volatile matter content is determined in accordance with ISO 3251. Using the non-volatile matter by volume results obtained in accordance with this document, it is possible to calculate the practical spreading rate of coating materials. This method specifies an additional shape of plate to those described in ISO 3233-1 and is suitable for all products which can be applied by dipping. This document is not applicable to coating materials which exceed the Critical Pigment Volume Concentration (CPVC). Annex A gives an overview of the existing methods for the determination of non-volatile matter content and of non-volatile matter volume.

Beschichtungsstoffe - Bestimmung des Volumens nichtflüchtiger Anteile - Teil 2: Verfahren mit Bestimmung des Gehaltes an nichtflüchtigen Anteilen nach ISO 3251 und Bestimmung der Trockenfilmdichte beschichteter Probenplatten nach dem Archimedes-Prinzip (ISO 3233-2:2019)

Dieses Dokument legt ein Verfahren zum Ermitteln des Volumens der nichtflüchtigen Anteile (VnfA) von Beschichtungsstoffen durch die Bestimmung der praktischen Trockenfilmdichte fest. Bei diesem Verfahren wird das Volumen der nichtflüchtigen Anteile von Beschichtungsstoffen und ähnlichen Produkten durch Messen der Dichte der trockenen Beschichtung bei einer festgelegten Temperatur und für eine bestimmte Trocknungs-/Härtungsdauer bestimmt. Der Gahlt an nichtflüchtigen Anteilen wird nach ISO 3251 bestimmt.
Aus den nach diesem Dokument erhaltenen Ergebnissen des VnfA kann die praktische Ergiebigkeit von Beschichtungsstoffen berechnet werden.
Dieses Verfahren legt im Vergleich mit ISO 3233-1 eine weitere Form der Probenplatte fest und ist für alle Produkte anwendbar, die durch Tauchen aufgetragen werden können.
Dieses Dokument ist nicht anwendbar für Beschichtungsstoffe, die die kritische Pigment¬volumen¬kon¬zen-tration (KPVK) überschreiten.
Anhang A zeigt eine Übersicht über die bestehenden Verfahren zur Bestimmung des Gehaltes an nichtflüchtigen Anteilen und des Volumens nichtflüchtiger Anteile

Le présent document spécifie une méthode permettant de mesurer la teneur en volume de matière non volatile (NVv) de produits de peinture par détermination de la masse volumique pratique du feuil sec. Cette méthode détermine le pourcentage en volume de matière non volatile dans les peintures, vernis et produits assimilés par mesurage de la masse volumique d'un revêtement sec pour toute gamme de température et toute période de séchage ou de polymérisation spécifiées. La teneur en matière non volatile est déterminée conformément à l'ISO 3251.
La teneur en volume de matière non volatile déterminée conformément au présent document permet de calculer le rendement pratique d'application de produits de peinture.
Cette méthode spécifie une forme de plaque supplémentaire à celles décrites dans l'ISO 3233‑1 et elle est utilisable pour tous les produits qui peuvent être appliqués par immersion.
Le présent document ne s'applique pas aux produits de peinture qui dépassent la concentration pigmentaire volumique critique (CPVC).
L'Annexe A donne une vue d'ensemble des méthodes utilisées pour la détermination de la teneur en matière non volatile et du volume de la matière non volatile.

Ta standard določa metodo za določevanje prostorninskega deleža nehlapnih snovi (NVV) premaznih materialov z določevanjem praktične gostote suhe plasti filma. Ta metoda določa prostorninski delež nehlapnih snovi v barvah, lakih in sorodnih izdelkih z merjenjem gostote suhe plasti filma za poljuben temperaturni obseg in obdobje sušenja ali strjevanja. Vsebnost nehlapnih snovi je določena v skladu s standardom ISO 3251. Z rezultati nevnetljive snovi glede na prostornino, ki so pridobljeni v skladu s tem dokumentom, je mogoče izračunati hitrost nanašanja premaznih materialov v praksi. Ta metoda določa dodatno obliko plošče glede na tiste, opisane v standardu ISO 3233-1, in je primerna za vse izdelke, ki jih je mogoče uporabiti s potapljanjem. Ta dokument se ne uporablja za premaze, v katerih je presežena kritična koncentracija prostornine pigmenta (CPVC). V dodatku A je pregled obstoječih metod za določanje vsebnosti in prostornine nehlapnih snovi.

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

This second edition cancels and replaces the first edition (ISO 3233-2:2014), which has been technically
revised. The main changes compared to the previous edition are as follows:
— the definitions and sources in Clause 3 have been updated;
— a minimum mass of 25 mg of the coating on the plate has been added in 7.2.2, because measurements
and simulation calculations demonstrate the need for a minimum mass for the coated panel.

This document specifies a method for determining the non-volatile matter by volume (NV ) of
V
coating materials by determining the practical dry-film density. This method determines the volume
percentage of non-volatile matter in paints, varnishes and related products by measuring the density
of a dry coating for any specified temperature range and period of drying or curing. The non-volatile
matter content is determined in accordance with ISO 3251.
Using the non-volatile matter by volume results obtained in accordance with this document, it is
possible to calculate the practical spreading rate of coating materials.
This method specifies an additional shape of plate to those described in ISO 3233-1 and is suitable for
all products which can be applied by dipping.
This document is not applicable to coating materials which exceed the Critical Pigment Volume
Concentration (CPVC).
Annex A gives an overview of the existing methods for the determination of non-volatile matter content

3.1
non-volatile matter
NV
residue by mass obtained by evaporation under specified conditions
Note 1 to entry: Instead of the term “non-volatile matter” different terms, such as solid, dry residue, dry matter, solid
matter, stoving residue are being used commonly with the respective abbreviations. The term “non-volatile matter”
which is also applied in ISO 3251 should be used together with the abbreviation “NV” instead of these terms.
