The Gehman Stiffness Tester evaluates the torsional stiffness of rubber at low temperature according to ISO 1432. The testing operation is automatic and specimens are twisted by means of torsion wires having nominal torsional constants at programmed test temperature. The angle of twist produced at this time is detected and is sent to the PC.
The Low Temperature Retraction Tester evaluates the temperature at which a specimen reaches a certain specified contraction ratio while the temmperature of the specimen, which has been stretched to a certain level and frozen at a low temperature, is raised at a certain constant rate. The TR test is mainly used to determine the elastic recovery characteristics at a low temperature of the materials of which sealing performance is required, such as rubber seal components, hose etc.
Safety standards with regards to flammability of interior materials of automobiles are prescribed. The MVSS Flammability Tester is used to test flammability of such materials.
The Brittleness Temperature Tester evaluates specimens immersed in liquid at low temperature. Impact is applied by hammer at constant speed and evaluation is made from generation of cracks. Specimen Clamps OPTIONS
High temperature HDT Tester is designed for HDT and Vicat testing at temperatures exceeding 300°C. Temperature distribution is dramatically improved by controlling the placement of test specimens and the air flow in the chamber.
The Triple Parallel Plate Plastometer is used for conducting heat deformation test of electric wires, etc.
The Candle Type Flammability Tester evaluates the flammability of polymeric materials such as rubber, plastic, and fiber using the oxygen index method. The test method evaluates the relative flammability of materials by measuring the limiting oxygen concentration (oxygen index) at which a test specimen can barely continue to burn like a candle flame in a slowly rising mixture of oxygen and nitrogen gas.
The Cone Calorimeter measures heat release rate, oxygen consumed, heat release, etc. which predict degree of fire hazard of materials.
The Cable Flammability Tester evaluates burning resilience of an electric cable. It conforms to UL 1581.
The Thermal Conductivity Tester measures thermal conduvtivity of plastic materials during the transition from melted state to solid state. The tester is also capable of measuring the conductivity during the change of state from solid state to melted state.
The metal bath used for fogging test, etc. *Testing tubes are not provided.
The HDT/Vicat Tester uses a 2 steps split loading system to ensure simultaneous application of the load on the specimens, applying a consistent fixed stress to the specimens. Using their patented design of the stirring and circular flow, Toyoseiki HDT Tester is able to ensure the temperature uniformity of the oil bath. Equipped with high precision LVDT, and Pt100 temperature sensors at each station, Toyoseiki’s HDT Tester is able to provide consistent, stable results when measuring the temperature as the limiting distortion is reached.
