Plastics - Thermoplastic materials - Determination of Vicat softening temperature (VST) (ISO 306:2022)
This document specifies four methods for the determination of the Vicat softening temperature (VST) of thermoplastic materials:
— Method A50 using a force of 10 N and a heating rate of 50 °C/h;
— Method B50 using a force of 50 N and a heating rate of 50 °C/h;
— Method A120 using a force of 10 N and a heating rate of 120 °C/h;
— Method B120 using a force of 50 N and a heating rate of 120 °C/h.
The methods specified are applicable only to thermoplastics, for which they give a measure of the temperature at which the thermoplastics start to soften rapidly.
Kunststoffe - Thermoplaste - Bestimmung der Vicat-Erweichungstemperatur (VST) (ISO 306:2022)
1.1 Dieses Dokument legt vier Verfahren zur Bestimmung der Vicat-Erweichungstemperatur (VST) von Thermoplasten fest:
Verfahren A50 mit einer Kraft von 10 N und einer Heizrate von 50 °C/h;
Verfahren B50 mit einer Kraft von 50 N und einer Heizrate von 50 °C/h;
Verfahren A120 mit einer Kraft von 10 N und einer Heizrate von 120 °C/h;
Verfahren B120 mit einer Kraft von 50 N und einer Heizrate von 120 °C/h.
1.2 Die festgelegten Verfahren sind nur auf Thermoplaste anwendbar, für die sie eine Kennzahl der Temperatur liefern, bei der die Thermoplaste beginnen schnell zu erweichen.
Plastiques - Matières thermoplastiques - Détermination de la température de ramollissement Vicat (VST) (ISO 306:2022)
Le présent document spécifie quatre méthodes de détermination de la température de ramollissement Vicat (VST) des matières thermoplastiques:
— méthode A50 utilisant une force de 10 N et une vitesse d’élévation de la température de 50 °C/h;
— méthode B50 utilisant une force de 50 N et une vitesse d’élévation de la température de 50 °C/h;
— méthode A120 utilisant une force de 10 N et une vitesse d’élévation de la température de 120 °C/h;
— méthode B120 utilisant une force de 50 N et une vitesse d’élévation de la température de 120 °C/h.
Les méthodes spécifiées sont uniquement applicables aux thermoplastiques. Elles permettent de mesurer la température à laquelle le ramollissement de ces matières devient rapide.
Polimerni materiali - Plastomeri - Ugotavljanje temperature zmehčišča po Vicatu (VST) (ISO 306:2022)
Ta dokument določa štiri metode za ugotavljanje temperature zmehčišča plastomerov po Vicatu (VST):
– metoda A50 z uporabo sile 10 N in hitrosti segrevanja 50 °C/h;
– metoda B50 z uporabo sile 50 N in hitrosti segrevanja 50 °C/h;
– metoda A120 z uporabo sile 10 N in hitrosti segrevanja 120 °C/h;
– metoda B120 z uporabo sile 50 N in hitrosti segrevanja 120 °C/h.
Opisane metode se uporabljajo za polimerne materiale, za katere podajajo temperaturno meritev, pri kateri se plastomeri začnejo hitro mehčati.
