Binders for paints and varnishes - Determination of the viscosity of industrial cellulose nitrate solutions and classification of such solutions (ISO 14446:1999)

The document specifies a method for determining the viscosity of industrial cellulose nitrate, usually referred to as nitrocellulose, the nitrogen content of which can vary between 10, 7 % by mass and 12, 6 % by mass, depending on the type. It also gives a classification system for industrial cellulose nitrate solutions which is based on viscosity measurements made using this method. The use of a standard procedure results in "standard" types and avoids classification differences which could be caused by the fact that there are many ways of determining viscosity and a wide variety of solutions available.

Bindemittel für Beschichtungsstoffe - Bestimmung der Viskosität technischer Cellulosenitrat-Lösungen und Einteilung solcher Lösungen (ISO 14446:1999)

Diese Internationale Norm legt ein Prüfverfahren zum Bestimmen der Viskosität von technischen Cellulosenitrat-Lösungen, üblicherweise auch als Collodiumwolle bezeichnet, deren Stickstoffgehalt je nach Type zwischen 10,7 % und 2,6 % (Massenanteil) liegen kann, fest.
Sie beschreibt auch ein System zur Einteilung von technischem Cellulosenitrat (siehe Anhang A), welches auf der Viskositätsmessung nach diesem Verfahren beruht. Die Verwendung eines genormten Verfahrens führt zu Normtypen und verhindert unterschiedliche Einteilungen, bedingt durch vielfältige Arten von Viskositäts-messungen und eine Vielzahl von möglichen Lösemitteln.

Liants pour peintures et vernis - Détermination de la viscosité des solutions de nitrate de cellulose industrielles et classification de ces solutions (ISO 14446:1999)

La présente Norme internationale spécifie une méthode pour la détermination de la viscosité du nitrate de cellulose
industriel, habituellement désigné sous le nom de nitrocellulose, dont la teneur en azote peut varier entre 10,7 % en
masse et 12,6 % en masse, en fonction du type.
Elle établit également un système de classification des solutions de nitrate de cellulose industrielles (voir annexe A)
qui est fondé sur des mesurages de viscosité effectués à l'aide de cette méthode. L'emploi d'un mode opératoire
normalisé conduit à des types «normalisés» et évite des différences dans la classification qui pourraient être dues
au fait qu'il existe plusieurs manières de déterminer la viscosité et une large variété de solvants disponibles.

Določa metodo za ugotavljanje viskoznosti industrijskega celuloznega nitrata, po navadi imenovanega nitroceluloza, v katerem vsebnost dušika lahko variira med 10,7 % in 12,6 % mase, odvisno od tipa.

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 3.
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.
International Standard ISO 14446 was prepared by Technical Committee ISO/TC 35, Paints and varnishes,
Subcommittee SC 10, Test methods for binders for paints and varnishes.
