Two cylindrical (2.27Kg) 5 Pound metal electrodes shall have a
diameter of 63.5mm (2.5Inches) each having contacts of electrically
conductive materials with a shore-A (IRHD) durometer hardness of
70 (ASTM method D2240-1986). The resistance between the
electrodes shall be less than 1-Kilo ohms when measured at
10Volts or less on metallic surface. These electrodes confirm to ANSI/EOS/ESD-S4.1-1990 Standards.
