Sample Holder for Thin-Sheet-Insulation Dielectric Measurements up to 600 C

A sample holder is described in which thin-sheet-insulation materials may be placed for determining the dielectric properties from room temperature to 600 C (degrees centigrade). The type of electrode system is given along with the reasons for changing the method of measurement. The accuracy of the system is given along with the dielectric properties of two high temperature insulation materials.
