ASTM F1130-99(2014)
(Practice)Standard Practice for Inspecting the Coating System of a Ship
Standard Practice for Inspecting the Coating System of a Ship
SIGNIFICANCE AND USE
3.1 This practice establishes the procedure for the inspection of coating systems on board ships. It contains a series of diagrams to be used to report the extent of damage to coatings.
SCOPE
1.1 This practice covers a standard procedure for inspecting the coating system of a ship's topside and superstructure, tanks and voids, decks and deck machinery, and underwater hull and boottop during drydocking. Included are a standard inspection form to be used for reporting the inspection data, a diagram that divides topside and superstructure individual inspection areas, and a series of diagrams that are used to report the extent of damage to the coating system.
1.2 This practice is intended for use only by an experienced marine coating inspector.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

the superstructure forward; “SO” for other superstructure, that

hull starboard; and “HP” for hull port.)

Fig. 15. Enter the code for the area being inspected. (For
example, enter “B” for the bottom of tank inspection, “A” for
the aft bulkhead, and so forth.) A complete list of tank
segments and their codes is shown in Fig. 15.
7.1.2 The underwater hull and boottop are segmented into
twelve distinct inspection areas. Enter the code for the area
being inspected. (For example, enter “P1” for the port bow
inspection, “S1” for the starboard bow inspection, and so

shown in Fig. 16.
7.1.3 Decks and deck machinery vary so greatly between
ship types that the development of a general diagram with
logical inspection areas and inspection area codes is not
feasible. It should be the responsibility of the organization that
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).
