Plastics piping and ducting systems - Thermoplastics pipes and fittings - Determination of Vicat softening temperature (VST)

This standard specifies a method for determining the Vicat softening temperature (VST) of pipes and fittings (see note) of thermoplastics materials, based on method B of ISO 306:1987, i.e. using a force of (50-1) N and a rate of temperature increase of 50°C/h. A measure of the temperature is obtainable only for those thermoplastics for which the softening becomes rapid.

Kunststoff-Rohrleitungs- und Schutzrohrsysteme - Rohre und Formstücke aus Thermoplasten - Bestimmung der Vicat-Erweichungstemperatur (VST)

Diese Norm legt ein Verfahren zur Bestimmung der Vicat-Erweichungstemperatur (VST: Vicat softening temperature) von Rohren und Formstücken aus Thermoplasten fest. Das Verfahren basiert auf ISO 306:1987, Verfahren B, d.h. es wird eine Belastung von (50-1) N und eine Temperatursteigerungsrate von 50°C/h angewendet. Ein Messergebnis für die Temperatur ist nur bei den Thermoplasten zu erhalten, bei denen die Erweichung schnell eintritt.

Systemes de canalisations et de gaines plastiques - Tubes et raccords thermoplastiques - Détermination de la température de ramollissement Vicat (VST)

Cette norme spécifie une méthode d'essai pour déterminer la température de ramollissement Vicat (VST: Vicat softening temperature) des tubes et raccords thermoplastiques (voir note), adaptée a partir de la méthode B de l'ISO 306: 1987, c'est-a-dire utilisant une force de (50-1) N et un taux d'élévation de la température de 50°C/h. Une mesure de la température n'est réalisable qu'avec les seules matieres thermoplastiques dont le ramollissement est rapide.
