Table 1
Criteria for corrosion risk levels with referring to ASTM C876 [
4].
| | No | Reference Electrode (mV) | Corrosion risk level | | Cu/CuSO4 | Ag/AgCl | Standard Hydrogen | Calomel |
| | 1 | > (-200) | > (-100) | > (+120) | > (-80) | Low (10% risk of corrosion) |
| | 2 | (-200)– (-350) | (-100)– (-250) | (+120) – (-30) | (-80) – (-230) | Intermediate corrosion risk |
| | 3 | < (-350) | < (-250) | < (-30) | < (-230) | High ( >90% risk of corrosion) |
| | 4 | < (-500) | < (-400) | < (-180) | < (-380) | Severe corrosion |
