TM0211-2011-SG “Durability Test for Copper/Copper Sulfate Permanent Reference Electrodes for Direct Burial Applications”

Test method to measure properties and stability of Cu/CuSO4 permanent reference electrodes (PREs) under environmental stress.  Specifically measures migration of CuSO4 from - and chloride into - the PRE.

This standard describes a test method to measure specific physical properties and the relative stability of Cu/CuSO4 permanent reference electrodes (PREs) when they are subjected to specific environmental stresses. These reference electrodes, while “permanent” in the physical sense (they are not commonly removed), do exhibit a finite service life. This test method is intended to provide a measure of the relative durability that may be expected. The test method specifically focuses on the ability of the Cu/CuSO4 PRE to (1) resist migration of CuSO4 from within the PRE into its surrounding environment and (2) to resist the migration of chloride from its surrounding environment into the PRE. Key words: permanent reference electrode, PRE, copper/copper sulfate, CuSO4
