ASTM F1130-99

Standard Practice for Inspecting the Coating System of a Ship

SCOPE
1.1 This practice describes 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 the standard. The values given in parentheses are for information only.
1.4 This standard does not purport to address all of the safety problems, 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.

inspection areas, and inspection area codes and to make certain
that this same coding system is used during all subsequent
inspections.
