NACE TM02111-2011

This standard describes a test method to measure specific physical properties and the relative stability of Cu/CuSO4 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. This standard is maintained by Task Group 256.
