This part of GB/T 11026 specifies the minimum requirements for ventilated, electrically heated single-chamber ovens (with or without forced air circulation) for the evaluation of electrical insulation heat resistance, and also specifies the acceptance test and operation of aging ovens. Control experiments in . This standard applies to ovens operating within the entire temperature range or part of the range from 20 °C to 500 °C higher than the ambient temperature.
