GALVANIC PROTECTION

protected member　　        
auxiliary body　　　     

PROTECTION STATUS　　UNVERIFIED

The auxiliary surface had already
taken the visible loss
before continuity was established.

The specification records
both designations in one field.
No conductive path
can be recovered from the record.

OPEN CIRCUIT

A more negative body
protects another only through
one electrolyte
and an unbroken path.

Here, preferential loss
cannot be assigned.
The auxiliary surface may be
marked, weathered, exhausted;
the protected member receives
none of the resulting current.

The only completed transfer
is the one written
onto the auxiliary surface.
