APPENDIX A (continued)
Get additional IR drop and voltage readings to establish circuit.
Current requirement test (for cathodic protection). At least cursory
current requirement tests should usually be conducted if there is any
chance of using cathodic protection at the site.
Test using an artificial ground bed for both magnesium anode and
impressed current designs.
Extent of testing is determined by the scope of work laid out by
the client. (Is all design data to be included with this
For existing cathodic protection:
Visually inspect all equipment.
Test to determine protection being given and possible
Get operating record.
Find out when installed and turned on.
Miscellaneous - Note any other corrosion problems (chemical, water,
atmospheric, etc.) that could use further detailed study.
Consulting Work To Be Accomplished:
Contact all plant personnel who have knowledge of structures being
studied and get all possible information from them.
Contact corrosion and maintenance engineers or operators in the area,
Oil transmission pipelines.
Gas transmission pipelines.
Gas distribution company.
Electrical power company.
Manufacturing plants in the area.
Corrosion Coordinating Committee.
Railroad (Do nearby railroads have signal systems?
propulsion - AC or DC?)
