ASTM's insulating material standards are instrumental in specifying, evaluating, and testing the electrical and physical properties of materials used primarily as electrical insulation in devices and related equipments. These properties include dielectric breakdown voltage, dielectric strength, AC loss, permittivity (dielectric constant), DC resistance and conductance, dissipation factor, ion exchange capacity, ionic resistivity, and other physical properties. These electrical insulating material standards allow manufacturers, particularly those in the semiconductor industry, to examine and asses such materials and equipments to ensure their qualification for safe use.
