Thermal Stability Test Apparatus is used to measure/ check thermal stability of pvc insulation & sheath of electric cables as per is 5831. Measures thermal stability time in minutes required to change the ph value of 5 to 3 of a universal indicating ph paper placed in a glass tube containing sample and heated in a thermostatically controlled heating chamber at specified temp. Of 200 °c ± 0.5 °c. New model incorporates a specially designed heating block which eliminated use of expensive silicone oil as in a conventional model.
We are offering Ageing Oven Cables which are subjected to many types of physical and chemical changes. The severity of exposures, both in temp & time, determines the extend & type of change that takes place. This test makes an assessment of change in tensile strength and elongation of materials on subjecting them to accelerated ageing in air. These oven designed to provide 8-20 changes of air per hour, at controlled temperature and extended duration up to 72 hours or longer. Hydraulic thermostat for an accuracy better than ±2°c.
