Standard Practice for
Inspecting the Coating System of a Ship
This standard is issued under the fixed designation F 1130; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

authorizes the inspections to develop the ship diagram, logical
inspection areas, and inspection area codes and to make certain
that this same coding system is used during all subsequent
inspections.

requires more than one day, enter the date the inspection is
completed.

ship (for example, Nassco No. 1182).

name.
