Cathodic Protection  Procedures - Diagnostic Testing

حفاظت کاتدی - آزمون دیاگنوستیک (ملزومات جریان)

ABSTRACT

The purpose of  diagnostic testing (DT)  is to outline a process to test for deficiencies  in a cathodic protection (CP) system, to identify  the cause(s)  of  such deficiencies, and to determine the requirements  to enhance the level of CP  to the structure. In an existing CP system, the DT is to first determine  if  the cause of  low CP levels can be eliminated and, if  not, what additional current is required, in addition  to how and where it can be applied. The CP Technician must have a good understanding of  the criteria as well as  the special conditions and precautionary notes that apply  to  these  criteria.
