New Test Method for Measuring Corrosion Rate of Uncoated Reinforcing Steel in Concrete

1. Scope

The scope of the Committee shall be the promotion of knowledge, the stimulation of research, the collection of engineering data, and the development of standard test methods, practices, guides, classifications, specifications and terminology relating to corrosion and methods for corrosion-protection of metals. The work of this Committee will be coordinated with other ASTM Committees and other organization having mutual interest.


Concrete reinforcement corrosion; electrochemical corrosion monitoring; polarization resistance; concrete durability; concrete inspection and evaluation


Reinforcing steel corrosion monitoring and inspection is done frequently for concrete structures susceptible to corrosion. The results are typically used to locate areas with corrosion activity, project future damage to concrete, differentiate areas suffering distress due to corrosion from these suffering other degradation mechanisms and plan for repair and rehabilitation strategies. Due to wide interest in corrosion monitoring, several commercial devices are already available. The user typically follows manufacturers' recommendations when performing the measurements. However, these recommendations can vary from one device to another (e.g. different scan rates, surface preparation methods, IR correction techniques, etc.) Therefore, there is a need to standardize these methods and provide guidance to the user in order to ensure the results are comparable.

The title and scope are in draft form and are under development within this ASTM Committee.
