1 Scope 1.1 GB/T 1634 specifies methods for the determination of the temperature of deflection under load (flexural stress under three-point loading) of plastics. Different types of test specimen and different constant loads are defined to suit different types of material. 1.2 This Part of GB/T 1634 gives a general test method; Part 2 gives specific requirements for plastics, ebonite and long-fibre-reinforced composites, while Part 3 gives specific requirements for high-strength thermosetting laminates. 1.3 The methods specified are suitable for assessing the relative behavior of different types of material at elevated temperature under load at a specified rate of temperature increase. The results obtained do not necessarily represent maximum applicable temperatures, because in practice essential factors such as time, loading conditions and nominal surface stress may differ from the test conditions. True comparability of data can only be achieved for materials having the same room-temperature flexural modulus. 1.4 The methods specify preferred dimensions for the test specimens. Tests which are carried out on specimens of different dimensions, or on specimens which are prepared under different conditions, may produce different results. Consequently, when repeatable data are required, sample preparation conditions and test variables should be carefully controlled and recorded. 1.5 Data obtained using the test methods described may not be used to predict actual end-use performance. The data are not intended for design analysis or predicting the endurance of materials at elevated temperatures. 1.6 For Part 2 of GB/T 1634, two test specimen positions are allowed. However, the flatwise position is the preferred and recommended one, while testing in the edgewise position is described as optional only. It is intended to remove this specimen position altogether on occasion of the next revision of this standard. 1.7 This method is commonly known as the HDT test (heat deflection test or heat distortion test), although there is no official document using this designation. 2 Normative References The following documents contain provisions which, through reference in this standard, constitute provisions of this standard.
