Test device for execution of hdt - and - vicat tests on test specimens made of plastic or synthetic material, comprising:– a support structure (48, 50) for mounting of at least strive test specimens (12),– at least one member for the application of a load (56) which, with respect to the support structure (48, 50) can be moved and has a head (60) which for the application of a force on the test specimens (12) serves,– Means (64) for measuring the movement of the organ to the application of force (56) based on the support structure (48, 50) and– a container (18), which a means for transfer of heat (26), in which the at least one test specimens (12) can be embedded, wherein the container (18) with heating means (24) is connected, which serve the purpose of the temperature of the heat transmission by means (26) to increase gradually,characterized in that– the heat transfer medium, a bed of powder (26), which is fluidized with compressed air; and– the test apparatus includes a..
