EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 75-1 testing. This standard gives a general test method for determining the deflection temperature of plastics under load (bending stress under three-point loading).
Different test specimen types and different constant loads are defined to suit different material types. ISO 75-2 specifies special requirements for plastics (including filled plastics and fiber-reinforced plastics with a fiber length of up to 7,5 mm before processing) and ebonite, while ISO 75-3 gives special requirements for high.
Strength thermosetting laminates and long fiber reinforced plastics with a fiber length of more than 7,5 mm before processing.
The specified methods are suitable for evaluating the relative behavior of different types of materials at high temperature under load at a given rate of temperature rise.
The results obtained do not represent the maximum applicable temperatures because in practice fundamental factors such as time, loading conditions and nominal surface tension may differ from the test conditions. True comparability of data can only be obtained for materials with the same room temperature flexural modulus.
Data obtained using the test methods described are not used to estimate actual end-use performance. The data are not intended for design analysis or estimation of the durability of materials at elevated temperatures.
This method is commonly known as heat deflection temperature or heat distortion temperature (HDT) testing, although there is no official document using this nomenclature.
