Plastics - Determination of viscosity using a falling-ball viscometer - Part 1: Inclined-tube method (ISO 12058-1:2018)
This document specifies the general principles of a method, using an inclined‑tube falling‑ball
viscometer, for determining the viscosity of polymers and resins in the liquid emulsified or dispersed
state. It is intended for application to liquids over a viscosity measurement range of 0,6 mPa·s to
250 000 mPa·s (temperature range −20 °C to +120 °C) for which the shear stress and shear rate are
proportional, i.e. the viscosity is independent of the shear rate. This ideal behaviour is commonly
known as Newtonian behaviour. If a liquid differs significantly from this behaviour, different results
can be obtained with the different balls of a falling‑ball viscometer or from viscometers with different
geometries, such as capillary and rotational viscometers.

Plastiques - Détermination de la viscosité au moyen d'un viscosimètre à chute de bille - Partie 1: Méthode du tube incliné (ISO 12058-1:2018)
Le présent document spécifie les principes généraux d'une méthode utilisant un viscosimètre à chute de bille dans un tube incliné pour la détermination de la viscosité des polymères et des résines à l'état liquide en émulsion ou en dispersion. Il est applicable, dans une plage de mesurage de la viscosité de 0,6 mPa·s à 250 000 mPa·s (plage de température de −20 °C à +120 °C), aux liquides dont la contrainte de cisaillement et la vitesse de cisaillement sont proportionnelles, ce qui signifie que la viscosité de ces liquides est indépendante de la vitesse de cisaillement. Ce comportement idéal est couramment dénommé «visco-élasticité newtonienne». Lorsque les caractéristiques d'un liquide donné ne correspondent pas à ce comportement, il arrive que l'on obtienne des résultats différents quand on utilise des billes différentes ou des viscosimètres de géométries différentes, tels que les viscosimètres capillaires et rotatifs.
Polimerni materiali - Določanje viskoznosti z uporabo viskozimetra s padajočo kroglico - 1. del: Metoda z nagnjeno cevjo (ISO 12058-1:2018)
Ta dokument določa splošna načela metode z uporabo viskozimetra s padajočo kroglico po nagnjeni cevi za določanje viskoznosti polimerov in smol v tekočem emulgiranem ali dispergiranem stanju. Uporablja se za tekočine v merilnem območju viskoznosti od 0,6 mPa s do 250.000 mPa s (temperaturno območje od –20 °C do 120 °C) s sorazmerno strižno napetostjo in strižno hitrostjo, tj. viskoznost je neodvisna od strižne hitrosti. Te idealne lastnosti so splošno znane kot Newtonove lastnosti. Če so lastnosti tekočine bistveno drugačne od teh, lahko pride do različnih rezultatov z različnimi kroglicami viskozimetra s padajočo kroglico ali z viskozimetri različnih geometrij, kot so kapilarni in rotacijski viskozimetri.

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.

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
