Thermoplastic and elastomeric insulation & sheath exposed to heat are subjected to many type of physical & chemical changes. The severity of exposures, both in temp. & time, determines the extent & type of change that takes place. This test makes an assessment of change in tensile strength and elongation of materials on subjection them to accelerated ageing in air. Oven designed to provide 8-20 changes of air per hour, at controlled temp.And extended duration up to 72 hours of longer.
