The ASTM D2436 standard specifies the requirements for forced convection laboratory ovens for electrical insulation. It specifies the design, construction, performance and other requirements of such ovens, with detailed regulations on key indicators such as Temperature uniformity and air circulation rate. The standard is designed to provide a reliable basis for relevant practitioners in the field of electrical insulation to ensure that laboratory ovens can accurately simulate the working environment of electrical insulation materials, help to accurately detect material performance, and improve the detection mass of electrical product insulation performance and the overall industry standard.
