reference electrode. Two commonly used reference
electrodes are listed below along with their voltage
equivalent (at 25°C [77°F]) to -850 mV referred to a
saturated copper/copper sulfate reference electrode:
6.4.1.1 Saturated KCl calomel reference
electrode: -780 mV; and
6.4.1.2 Saturated silver/silver chloride reference
electrode used in 25 ohm-cm seawater: -800 mV.
6.4.2 In addition to these standard reference
electrodes, an alternative metallic material or structure
may be used in place of the saturated copper/copper
sulfate reference electrode if the stability of its
electrode potential is ensured and if its voltage
equivalent referred to a saturated copper/copper
sulfate reference electrode is established.
