Plastics - Determination of melting behaviour (melting temperature or melting range) of semi-crystalline polymers by capillary tube and polarizing-microscope methods (ISO 3146:2022)

This document specifies two methods for evaluating the melting behaviour of semi-crystalline polymers.
a) Method A: Capillary tube
This method is based on the changes in shape of the polymer. It is applicable to all semi-crystalline polymers and their compounds.
NOTE 1   Method A can also be useful for the evaluation of the softening of non-crystalline solids.
b) Method B: Polarizing microscope
This method is based on changes in the optical properties of the polymer. It is applicable to polymers containing a birefringent crystalline phase. It might not be suitable for plastics compounds containing pigments and/or other additives which can interfere with the birefringence of the polymeric crystalline zone.
NOTE 2   Another method applicable to semi-crystalline polymers is described in ISO 11357‑3.

Kunststoffe - Bestimmung des Schmelzverhaltens (Schmelztemperatur oder Schmelzbereich) von teilkristallinen Polymeren im Kapillarrohr- und Polarisationsmikroskop-Verfahren (ISO 3146:2022)

Dieses Dokument legt zwei Verfahren zur Ermittlung des Schmelzverhaltens von teilkristallinen Polymeren fest.
a)   Verfahren A: Kapillarrohr
Dieses Verfahren beruht auf den Veränderungen der Form des Polymers. Es ist auf alle teilkristallinen Polymere und ihre Formmassen anwendbar.
ANMERKUNG 1   Verfahren A kann auch zur Bestimmung der Erweichung nichtkristalliner Feststoffe angewendet werden.
b)   Verfahren B: Polarisationsmikroskop
Dieses Verfahren beruht auf den Veränderungen der optischen Eigenschaften des Polymers. Es ist auf Polymere mit doppelbrechender kristalliner Phase anwendbar. Für Kunststoff-Formmassen, die Pigmente und/oder andere Zusätze enthalten, die die Doppelbrechung der polymeren, kristallinen Zone stören können, könnte es möglicherweise ungeeignet sein.
ANMERKUNG 2   Ein weiteres, für teilkristalline Polymere anwendbares Verfahren ist in ISO 11357 3 beschrieben.

Plastiques - Détermination du comportement à la fusion (température de fusion ou plage de températures de fusion) des polymères semi-cristallins par méthodes du tube capillaire et du microscope polarisant (ISO 3146:2022)

Le présent document spécifie deux méthodes d’évaluation du comportement à la fusion des polymères semi-cristallins.
a) Méthode A : Tube capillaire
Cette méthode repose sur l’évaluation des changements de forme du polymère. Elle est applicable à tous les polymères semi-cristallins ainsi qu’à leurs compositions.
NOTE 1   La méthode A peut également être utile pour évaluer le ramollissement des solides non cristallins.
b) Méthode B : Microscope polarisant
Cette méthode repose sur l’évaluation des variations des propriétés optiques du polymère. Elle est applicable aux polymères comportant une phase cristalline biréfringente. Elle peut ne pas convenir pour les compositions de plastiques contenant des pigments et/ou d’autres additifs qui pourraient interférer avec la biréfringence de la zone cristalline polymérique.
NOTE 2   Une autre méthode applicable aux polymères semi-cristallins est décrite dans l’ISO 11357‑3.

Polimerni materiali - Ugotavljanje temperature ali območja taljenja kristaliničnih polimerov s kapilarno cevko in polarizacijskim mikroskopom (ISO 3146:2021)

Ta dokument določa dve metodi za vrednotenje lastnosti kristaliničnih polimerov pri taljenju.
a) Metoda A: kapilarna cevka
Ta metoda temelji na spremembah oblike polimera. Uporablja se za vse kristalinične
polimere in njihove zmesi.
OPOMBA 1: Metoda A je lahko uporabna tudi za vrednotenje mehčanja nekristaliničnih trdnih snovi.
b) Metoda B: polarizacijski mikroskop
Ta metoda temelji na spremembah optičnih lastnosti polimera. Uporablja se za polimere
z dvolomno kristalinično fazo. Metoda morda ni primerna za zmesi polimernih materialov, ki vsebujejo
pigmente in/ali druge dodatke, ki lahko vplivajo na dvolomnost polimernega kristaliničnega
območja.
OPOMBA 2: Druga metoda, ki se uporablja za kristalinične polimere, je opisana v standardu ISO 11357-3.
