Plastics - Determination of temperature of deflection under load - Part 3: High-strength thermosetting laminates (ISO 75-3:2004)
ISO 75-3:2004 specifies a method for the determination of the temperature of deflection under load of high-strength thermosetting laminates and compression-moulded long-fibre-reinforced plastics in which the fibre length is greater than 7,5 mm. The flexural stress used is not fixed, as in ISO 75-2, but is a fraction (1/1000) of the initial (room-temperature) flexural modulus of the material under test. This allows the method to be applied to materials with a wide range of flexural moduli.
Kunststoffe - Bestimmung der Wärmeformbeständigkeitstemperatur - Teil 3: Hochbeständige härtbare Schichtstoffe und langfaserverstärkte Kunststoffe (ISO 75-3:2004)
Dieser Teil von ISO 75 beschreibt ein Verfahren zur Bestimmung der Wärmeformbeständigkeitstemperatur unter Last (Biegespannung) von hochbeständig härtbaren Schichtstoffen. Die Biegespannung ist nicht fest vorgeschrieben, wie in Teil 2 dieser Internationalen Norm, sondern sie ist eine Funktion (1/1000) des Anfangs- (Raumtemperatur) Biegemoduls des geprüften Werkstoffs. Dadurch ist es möglich, das Verfahren auf Werkstoffe mit einem großen Bereich von Biegemoduln anzuwenden.

Plastiques - Détermination de la température de fléchissement sous charge - Partie 3: Stratifiés thermodurcissables à haute résistance (ISO 75-3:2004)
L'ISO 75-3:2004 spécifie une méthode permettant de déterminer la température de fléchissement sous charge de stratifiés thermodurcissables à haute résistance et de plastiques renforcés de fibres longues moulés par compression dans lesquels la longueur de fibre est supérieure à 7,5 mm. La contrainte de flexion utilisée n'est pas fixée, comme dans l'ISO 75-2, mais représente une fraction (1/1 000) du module initial de flexion (à température ambiante) du matériau soumis à essai. La méthode peut ainsi être appliquée à des matériaux caractérisés par une large gamme de modules de flexion.
